CoNiCrMo alloy
CoCrMo alloy is a kind of cobalt base alloy, is a kind of wear resistance and corrosion resistance cobalt base alloy. The original cobalt base alloy was cobalt-chromium binary alloy, later developed into cobalt-chrome-tungsten ternary, and then cobalt-chrome-molybdenum alloy was developed later. Cobalt-chrome-molybdenum alloy is based on cobalt as the main component, containing considerable amounts of chromium, molybdenum and a small amount of nickel, carbon and other alloying elements, occasionally also contains a class of alloy iron. Depending on the composition of the alloy, they can be made into welding wire, powder for hard surfacing, thermal spraying, spray welding and other processes, can also be made into casting and forging parts and powder metallurgy parts.
CoNiCrMo alloy, formerly known as MP35N, is one of the promising forged cobalt-based alloys. It is highly resistant to corrosion in seawater (containing chloride ions) under stress. Cold working can increase the strength of the alloy. However, cold working has considerable difficulties, especially in the manufacture of large devices, such as hip handles, where hot forging is suitable.
The forged CoNiCrMo alloy is similar to the cast CoCrMo alloy in terms of wear resistance and high tensile strength, so it is suitable for use in areas that require long life without fracture or stress fatigue, such as artificial joints at the hip, for the difficult and expensive operation of embedding implants deep into the femoral bone marrow catheter. This advantage is very important.
From high-end environmental protection CoCrMo(dental, human body support and other medical biological materials)C gold, compared with gold and silver and other traditional jewelry materials more environmental protection and health; Its color is infinitely close to platinum; So around 2010, "bright platinum" jewelry is popular in Europe and the United States, with the label of "fashion", "health" and "environmental protection". 2, # bright platinum jewelry # known as "public platinum" "affordable platinum" # bright platinum jewelry #, the use of modern technology advantages, combined with the experience of traditional jewelry, in metallurgical quality, production process and other aspects of the innovation, inherited the advantages of platinum luster, make up for the platinum easy to deform, black, away from the lack of public, is the public affordable platinum, Hence the name "Volkswagen Platinum".

The elastic modulus of cobalt-based alloy does not change with the change of maximum tensile strength, and is in the range of 220 to 234 GPa, which is higher than that of other materials such as stainless steel.
CoCrMo alloys are particularly susceptible to work hardening and cannot be manufactured in the same way as other metals. Instead, vacuum precision casting is used. The mold temperature control can control the grain size of the castings. The coarse grains are formed at higher temperature, which will reduce the strength, but the larger carbide separated from each other will be precipitated and the brittleness of the materials will be reduced.
Due to the limited Co resources and the difficulty of production and preparation, this series of alloys has not been widely used as nickel-based alloys.
