The atomic weight is 58.9332, hexagonal crystals are densely arranged, and the common valence is 2. Cobalt is a shiny steel-gray metal, hard and brittle. Ferromagnetic heating to 1150℃ When the magnetism is lost, it is not affected by water at room temperature and is also very stable in humid air. Cobalt-based alloy is a germplasm alloy that can withstand various wear, corrosion and high temperature oxidation. That is commonly referred to as cobalt-chromium-tungsten (molybdenum) alloy or Stelli (cobalt-based alloy with cobalt as the main component, containing a considerable amount of nickel, chromium, tungsten and a small amount of molybdenum, niobium, tantalum, titanium, haze. 2, What is the most significant feature of cobalt chromium molybdenum alloy? Cobalt-chromium-molybdenum alloy (CoCrMo) It is one of the cobalt-based alloys, often referred to as Stellite, an alloy that is wear-resistant and corrosion-resistant to cobalt. The initial cobalt-based alloy was a cobalt-chromium binary alloy, and then developed into a cobalt-chromium-tungsten ternary, and then developed into a cobalt-chromium-molybdenum alloy. Cobalt-chromium-molybdenum alloy is a cobalt as the main component, containing a considerable amount of chromium, molybdenum and a small amount of nickel, carbon and other alloying elements, occasionally containing iron alloys. Depending on the different components in the alloy, they can be made into welding wires and hard-faced surfacing powders. Casting and forging parts and powder metallurgy parts can also be made into casting and forging parts and powder metallurgy parts. 3, cobalt chromium alloy and titanium alloy which is good?

In order to improve and enhance some properties of steel and make it obtain some special properties and the elements intentionally added in the smelting process are called alloying elements. Common alloying elements are chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, silicon, manganese, aluminum, copper, boron, rare earth and so on. Phosphorus, sulfur, nitrogen, etc., also act as alloys in some cases. 1 Cr 24 Chromium can increase the hardenability of steel and has a secondary hardening effect, which can improve the hardness and wear resistance of carbon steel without making the steel brittle. When the content exceeds 12%, the steel has good high-temperature oxidation resistance and oxidation corrosion resistance, and also increases the thermal strength of the steel. Chromium is the main alloying element of stainless steel acid-resistant steel and heat-resistant steel. Chromium can improve the strength and hardness of carbon steel in rolling state, and reduce the elongation and shrinkage of section. When the chromium content exceeds 15%, the strength and hardness will decrease, and the elongation and section shrinkage will increase accordingly. The parts containing chromium steel are easy to obtain higher surface machining quality by grinding. The main role of chromium in the tempered structure is to improve the hardenability, so that the steel after quenching and tempering has better comprehensive mechanical properties, in the carburized steel can also form chromium carbide, so as to improve the wear resistance of the material surface. Spring steels containing chromium are not easy to decarburize during heat treatment. Chromium can improve the wear resistance, hardness and red hardness of tool steel, and has good tempering stability. In electrothermal alloys, chromium can improve the oxidation resistance, resistance and strength of the alloy. 2 Ni 28 Nickel strengthens ferrite and refines pearlite in steel, the overall effect is to …

Nickel-based alloy is the most widely used superalloy with the highest high temperature strength.  The main reasons are:  More alloying elements can be dissolved in the nickel-based alloy, and the structure stability can be maintained.  The coherent ordered A3B intermetallic compound γ'[Ni3(Al, Ti)] phase can be formed as the strengthening phase, so that the alloy can be effectively strengthened, and the high temperature strength is higher than that of iron and cobalt based superalloys.  3. The chromium-containing nickel-based alloy has better oxidation resistance and gas corrosion resistance than the iron-based superalloy. Nickel-based alloys contain more than ten elements, of which Cr mainly plays an anti-oxidation and anti-corrosion role, and other elements mainly play a strengthening role. According to their strengthening mode of action can be divided into: solid solution strengthening elements, such as tungsten, molybdenum, cobalt, chromium and vanadium;  Precipitation strengthened elements such as aluminum, titanium, niobium and tantalum; Grain boundary strengthening elements such as boron, zirconium, magnesium and rare earth elements. Nickel-based superalloys have solid solution strengthened alloy and precipitation strengthened alloy according to the strengthening method. » Solid solution strengthened alloy It has certain high temperature strength, good oxidation resistance, thermal corrosion resistance, cold resistance, thermal fatigue performance, and good plasticity and weldability, and can be used to manufacture parts with high working temperature and little stress, such as the combustion chamber of gas turbines. » Precipitation-strengthened alloy Generally, three strengthening methods of solid solution strengthening, precipitation strengthening and grain boundary strengthening are integrated, so it has good high temperature creep strength, fatigue resistance, oxidation resistance and thermal corrosion resistance, and can be used to make components with high stress under high temperature, such as turbine blades and turbine disks of gas turbines. Nickel-based alloy has high strength and oxidation resistance at 650~1000℃. According to the main properties, it …

Hardenability and hardenability are two performance indexes to characterize the capacity of steel to accept quenching, and they are also important basis for material selection and use 1.Concept Of Hardenability And Hardenability Hardening is the ability of steel to achieve the highest hardness after hardening to martensite under ideal conditions. The main factor that determines the hardness of steel is the carbon content of the steel, more specifically the carbon content of the steel that is solidly dissolved in austenite during quenching heating. The higher the carbon content, the higher the hardness of the steel. The alloying elements in steel have little effect on hardenability, but have great effect on hardenability.   Hardenability means steel under certain conditions quenching to obtain the ability to quench the depth of the layer, mainly affected by the carbon content and alloying elements in austenite, refers to under specified conditions, determine the steel hardening depth and hardness and hardness distribution characteristics, steel hardenability is good and bad, commonly used to express the depth of the quench layer, the greater the depth of the quench layer, the better the hardenability of steel, The hardenability of steel mainly depends on its chemical composition. Good hardenability of steel can make the whole section of steel obtain uniform mechanical properties and the quenching medium with small quenching stress can be selected to reduce deformation and cracking   In addition, because hardenability and hardenability are two concepts, so after quenching hardness of steel, not necessarily high hardenability; Steels with low hardness may also have high hardenability. 2. Hardenability Evaluation Method The current universally accepted method in the heat treatment industry is HP-IVF method of Swedish IVF Company, which was pioneered by Dr.Soren Segerberg of Swedish IVF   2.1 Calculation formula for ISO9950 quenching oil hardening:   HP – IVF …

KOVAR, also known as ASTM F 15 alloy, is a controlled expansion alloy commonly used in metal seals, LIDS, lead frames, and electronic package bases for high integrity glass and ceramics. Kovar is made of nickel, cobalt and iron. This alloy is designed to accommodate the technological needs of computers, microwaves, hydrides, semiconductors and the space age, and as such, it is an important resource for the defense, aerospace and telecommunications industries.   The F15 undergoes a rigorous vacuum melting process to produce the highest level of cleanliness and a more uniform alloy. The ASTM F15 alloy (Kovar) is very stable, passing the standard phase transition test at -80℃ and remaining stable at -196℃. kovar is a nickel-cobalt-ferro alloy designed to be compatible with the thermal expansion characteristics of borosilicate glass (~5×10-6 /K between 30 and 200°C and ~10×10-6 /K up to 800°C) in order to achieve direct mechanical connection over a range of temperatures. It is used in electroplating conductors, into glass jackets of electronic components such as vacuum tubes (valves), X-ray and microwave tubes, and some light bulbs The name Kovar is often used as a general term for FeNi alloys with these particular thermal expansion properties. Note the related special Fe-Ni alloy Invar, which exhibits minimal thermal expansion. F15 nickel alloys usually harden fairly quickly, and the high pressures created by processing can cause hardening and slow progress, as well as cause warping in some materials. Make sure you have a rigid setting to work at a low speed, and try using sulphide mineral oil. When working Kovar (ASTM F15 alloy), it tends to be quite colloidal. The knife tends to go straight through the metal rather than cutting it. Complete control of heating is important when working F15, as excessive heat build-up can cause the alloy …
