Cobalt-based alloy powder has good wettability and lower melting point than carbides, mainly used on steel-based alloy substrates for parts requiring corrosion and thermal fatigue resistance. It features high hardness at high temperatures, wear & corrosion resistance, suits laser cladding, thermal spraying, plasma surfacing-applied in surface strengthening/reconditioning of engine valves, turbine blades, metallurgical equipment.
Cobalt-based alloy powder with moderate tungsten content.
