Paper Title:
Microstructure and Properties of Carbonitride Alloying Self-Shielded Wear-Resistant Coatings by HVAS
  Abstract

A kind of self-shielded carbonitride alloying flux-cored wire was developed. Wear resistant coatings was prepared on the surface of the Q235 low-carbon steel by HAVS using the wire. Detection and analysis on the microstructure and properties of the coatings were done by the equipments such as scanning electron microscope, microhardness tester and wear tester. The forming, the wear resistance and its mechanism of the coating were studied. The results show that the coating has good forming property, uniformity of microstructure and compact structure, but the coating also has large oxidate and porosity, this may due to gasforming and slagforming constituents in the wire; the coatings has high hardness, the average microhardness value reachs 510 HV0.1, and the highest value up to about 560 HV0.1; the coatings has good abrasive wear performance and bonding strength.
