Cobalt alloy is one of the most famous cobalt-based wear-resistant alloys, both excellent wear resistance and toughness, can adapt to most conditions, widely used, hardness 37-45HRC; mainly used for chemical wear plates, wear-resistant rods , Steam chemical valve seat, turbine blade protection, erosion-resistant sleeve, hot-dip galvanized sink roll and other parts. Compared with WR6, WR6B has better high temperature wear resistance.
The general cobalt-base superalloy lacks a coherent reinforcing phase. Although the mid-temperature strength is low (only 50-75% of the nickel-based alloy), it has higher strength at temperatures above 980 ° C, good thermal fatigue resistance, hot corrosion resistance And abrasion resistance, and has good weldability. Suitable for making aviation jet engines, industrial gas turbines, guide vanes and nozzle guide vanes for marine gas turbines, and diesel engine nozzles.
The size and distribution of carbide particles and the grain size of cobalt plate are sensitive to the casting process and the casting process parameters must be controlled in order to achieve the required long-term strength and thermal fatigue properties of the cast cobalt plate. Cobalt plate needs heat treatment, mainly to control the precipitation of carbides. For the cast Cobalt Plate, the first high-temperature solution treatment, the temperature is usually about 1150 ℃, so that all the primary carbides, including some MC-type carbide dissolved in solid solution; and then at 870-980 ℃ for aging treatment, so that Carbide (most commonly M23C6) re-precipitation.
Cobalt plate has a flat fracture stress-temperature relationship, but shows superior resistance to hot corrosion at temperatures above 1000 ° C compared to other high temperatures, probably because of the higher chromium content of the alloy, which is one of these alloys feature. The general cobalt-base superalloy lacks a coherent reinforcing phase. Although the mid-temperature strength is low (only 50-75% of the nickel-based alloy), it has higher strength at temperatures above 980 ° C, good thermal fatigue resistance, hot corrosion resistance And abrasion resistance, and has good weldability.
