Properties and application characteristics of self-bonding tungsten carbide composite powder

       Self-adhesive tungsten carbide composite powder is agglomerated and compounded by cobalt-coated tungsten carbide powder (or cobalt sintered tungsten carbide fine powder) and self-adhesive NiAl composite powder, or by adding NiCrBSi self-fluxing alloy powder for mixing. become. This composite coating is not suitable for wear and corrosion resistant coatings in liquid medium.



     The self-bonding tungsten carbide composite powder should be sprayed by gas-stabilized plasma. In order to reduce the burning loss of carbide, powder flame spraying is not used as much as possible.

     The coating has excellent resistance to fretting wear, sliding wear and hard surface wear, and prepares thin coatings that do not require machining or a small amount of machining, such as journals, bushings, piston pins, piston rods, face seals, balance discs Wait.
