Cobalt alloy resistant to abrasion and corrosion in aqueous solution

These alloys are all composed of 5%-13% Mo and thus resist corrosion in aqueous solutions. The brand is Ultimet,UNS R31233,(5% MO); stellite21,UNS R30021,(6%Mo); MP159, UNS R30159, Mo (7%); MP35N, UNS R30035, Mo (10%); Stellite703 (containing 12% Mo).

The advantages of forging method on wear resistance and corrosion resistance:

Forging technology is beneficial to corrosion resistance and wear resistance mechanism

Forging improves chemical homogeneity, which is of great importance for corrosion resistance. Commonly speaking, chemical homogeneity is "the army and the people unite as one, who can test the world". This unity (chemical homogeneity) maximizes the ability to resist corrosion.

Forging process improves toughness, elongation > 2% (casting, powder metallurgy or GTA wear resistant cobalt alloy elongation < 1%), improve the geometric structure of cobalt alloy internal strengthening phase precipitates, that is, block tungsten carbide in the microstructure to enhance the wear resistance. The grain size is refined and the grain boundary strength is enhanced. The resilience of this organizational structure has enhanced the ability to "defend the country".
