How to Improve Thermal Spray Coating Properties by Chemical Heat Treatment

       In order to improve the wear resistance of ordinary flame sprayed NI-based self-fluxing alloy coatings, plasma carburizing is carried out on the coating in the range of its melting treatment to generate carbides containing a small amount of Cr3C2 containing Mo and Fe near the coating. The wear test proves that its wear-resistant particle wear performance is comparable to that of the Cr3C2 coating prepared by high-speed gas flame spraying.

     How to use the combination of electroplating and thermal spray process technology to improve the performance of the spray coating?

     Use electroplating technology to seal the pores of the thermal spray coating to improve the wear resistance of the coating, or spray the same electroplating material on the electroplated layer, followed by heat treatment to diffuse the metal into the coating to improve the bonding strength of the sprayed layer etc. technology.
