Powder characteristics:

Cobalt-based alloy is a kind of hard alloy that can resist various types of wear and corrosion as well as high temperature oxidation. It is commonly known as cobalt-chrome-tungsten (molybdenum) or Stellite( an alloy invented by Elwood Hayness in 1907). Cobalt-based alloys are alloys in which cobalt is the principal component and contains significant amounts of nickel, chromium, tungsten and small amounts of molybdenum, niobium, tantalum, titanium, lanthanum, and occasionally 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, as well as cast and forged parts and powder metallurgy parts.

Applicable processes: 

According to its application, cobalt base alloy can be divided into cobalt base wear resistant alloy, cobalt base high temperature resistant alloy and cobalt base wear resistance and aqueous solution corrosion alloy. General working conditions, in fact, are both wear resistance and high temperature resistance or wear resistance and corrosion resistance, some working conditions may also require high temperature resistance and wear resistance and corrosion resistance, and the more complex working conditions, the more can reflect the advantages of cobalt-based alloy.

Powder application: 

General cobalt-based superalloys lack a uniform strengthening phase. Although the strength at medium temperature is low (only 50-75% of that of nickel-based alloys), they have high strength, good thermal fatigue resistance, thermal corrosion resistance and abrasion resistance at higher than 980, and good weldability. It is suitable for the production of guide vane and nozzle guide vane of aviation jet engine, industrial gas turbine, naval gas turbine and diesel nozzle, etc.
