Abstract: In order to prepare wear-resistant coating on the surface of carbon steels and make
the expansion coefficient of coating close to that of substrate and reduce stress in coating,
mechanically mixed powders of 80%Fe, 13%P and 7%C were used to prepare iron-based
wear-resistant coating by plasma spraying. The bonding strength was tested using binder dual
tensile test method. The hardness in the coating was analyzed by surface microhardness method.
And the wear resistance test of coating was carried out by MMW-2 (high temperature) friction
and wear testing machine using 40Cr cemented carbide as grinding materials. The results show
that the average bonding strength of the coating was 29 MPa, and the average microhardness
was 805 HV50, higher than that of ceramic coating. The coating had better wear resistance, and
the coating abrasion loss was around 36 mg which was about 1/13 of the grinding material. And
the wear mechanism of the coating was mainly abrasive wear.
