Composition of Cobalt-Based Alloys

Cobalt-based alloys usually use cobalt (Co) as the matrix element, combined with other elements to enhance specific properties. Common alloying elements include:
Chromium (Cr): Improves corrosion resistance and oxidation resistance, usually 20-30%.
Nickel (Ni): Enhances high temperature strength and ductility, and the nickel content in some alloys can reach 20%.
Tungsten (W): Improves high temperature strength and wear resistance, usually 5-15%.
Molybdenum (Mo): Improves corrosion resistance and strength.
Carbon (C): Used to form carbides (such as Cr23C6 or WC), enhance wear resistance and hardness.
Other elements: such as iron (Fe), manganese (Mn), silicon (Si), etc., used to fine-tune performance.
Cobalt-based alloys can be divided into the following categories according to their use:
Wear-resistant alloys: such as the Stellite series, with a high carbide content, suitable for high wear environments.
High temperature resistant alloys: such as Haynes alloys, emphasizing high temperature strength and oxidation resistance.
Corrosion-resistant alloys: such as Vitallium, used in the biomedical field.
