The excellent properties of cobalt-based alloy powder are due to its special chemical composition and microstructure. It is made of a variety of metal elements mixed in accordance with a certain proportion after high temperature melting, of which the content of cobalt is higher, so it has good hardness and corrosion resistance. At the same time, the alloy also contains an appropriate amount of iron, chromium and other elements, so that it has better wear resistance. In the manufacturing process, cobalt-based alloy powder is produced using an advanced powder metallurgy process. First, the metal elements are mixed according to a certain proportion, and then through high temperature melting, rapid cooling and other process steps, and finally get a fine, uniform alloy powder. This powder has a high degree of fluidity, filling and sintering properties, and can be processed into a variety of complex shapes of parts.
Cobalt-based alloys have high strength, good resistance to thermal fatigue, thermal corrosion and abrasion, and good weldability at temperatures above 980℃. Suitable for aviation jet engine, industrial gas turbine, ship gas turbine guide vane and nozzle guide vane and diesel nozzle etc.
