Plasma Spraying and Other Deposition Methods

• CoCrMo powder can be deposited onto a substrate using plasma spraying. A plasma torch is used to heat the powder particles to a high temperature, causing them to melt and bond to the substrate. Plasma spraying is often used to create coatings or thick layers of CoCrMo.
• Other deposition methods, such as laser cladding and electron beam physical vapor deposition, can also be used to produce CoCrMo coatings or components.

Additive Manufacturing

• CoCrMo powder can be used in additive manufacturing processes, such as powder bed fusion and directed energy deposition. These processes allow for the creation of complex shapes and structures that would be difficult or impossible to produce using traditional manufacturing methods.
