CoCrMo alloys are known for their high wear resistance and corrosion resistance

Overview of 3D metal printing CoCrMo powder

CoCrMo alloy (cobalt-chromium molybdenum) is one of the cobalt-base alloys, is also commonly known as a Stellite alloy, is a kind of wear and corrosion resistance of the cobalt-base alloy.CoCrMo alloys are particularly susceptible to work hardening and therefore cannot be manufactured in the same way as other metals, requiring vacuum precision casting instead. Controlling the mold temperature can control the grain size of the casting. The formation of coarse grains at higher temperatures will reduce the strength, but it will also precipitate large and far apart carbides and reduce the brittleness of the material.CoCrMo alloys are known for their high wear resistance and corrosion resistance. Because of their good biocompatibility, they are widely used in surgical prostheses. The microstructure and properties of CoCrMo alloys, such as wear-resistance and hardness, are mainly determined by the carbon content and the heat treatment method adopted. Cobalt-Cr-Mo (CoCrMo) metal-on-metal hip prosthesis has been revived due to its excellent wear properties. However, particle wear fragments and metal ions released from CoCrMo alloys may cause carcinogenesis, hypersensitivity, local and general tissue toxicity, genotoxicity, and inflammatory properties.

The original cobalt base alloy is a cobalt-chromium binary alloy, later developed into a cobalt-chromium tungsten ternary component, and then later the development of cobalt-chromium molybdenum alloy.The cobalt-chromium molybdenum alloy is mainly composed of cobalt and contains a considerable amount of chromium, molybdenum and a small amount of nickel, carbon and other alloying elements, and occasionally also contains alloys such as iron. Cobalt and chromium are two basic elements of cobalt-based alloys while adding molybdenum can produce finer grains and higher strength after casting or forging. Cobalt-Cr-Mo alloys are basically divided into two classes: one is CoCrMo alloys, which are usually cast products, and the other is ConicrMo alloys, which are usually (hot) forged and precision machined. Cast CoCrMo alloys have been used in dentistry for decades and are currently used to make artificial joints, while forged ConicrMo alloys are used to make heavy joints that can withstand heavy loads such as knees and hips. However, as a joint implant material, CoCrMo alloy will release harmful ions such as Co, Cr and Ni after implantation in the human body. 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, as well as cast and forged parts and powder metallurgy parts.

Application of 3D metal printing CoCrMo powder

Cobalt-chrome alloys or ceramic materials (alumina or zirconia) are used to make orthopedic implants. These biomedical materials are biocompatible, resistant to corrosion, degradation and wear, and they have the mechanical properties to replicate the structures they are intended to replace.

CoCrMo alloys can be highly resistant to corrosion in seawater (containing chloride ions) when subjected to stress. Cold processing can increase the strength of the alloy, but it is quite difficult to cold processing, especially for large devices such as hip handles, only hot forging is suitable.

Cast CoCrMo alloys have the advantages of good fatigue resistance and high tensile strength, so they are suitable for use in artificial joints that require a long life without fracture or stress fatigue, such as the hip joint. This advantage is important for the difficult and expensive operation of inserting the implant deep into the femoral marrow catheter.

The elastic modulus of cobalt-based alloys does not change with the maximum tensile strength, which ranges from 220 to 234 GPa and is higher than that of other materials such as stainless steel.

Due to limited Co resources and difficulty in production and preparation, this series of alloys have not been widely used as nickel-based alloys.

CoCrMo (CoCrMo) powder can also be used in laser/electron beam additive manufacturing (SLM/EBM), powder metallurgy (PM), spraying, welding and other processes. It is also used for 3D printing of biomedical materials such as teeth, human scaffolds and artificial joints.
