ABSTRACT

This paper presents a study on the effect of the Cr3C2 carbide content on the adhesion and micro-hardness of the Cr3C2-NiCr coatings coated on 16Mn alloy steel surface by using a plasma spraying technique. The results show that when the carbide content increases from 50% up to 80% by mass, the adhesion of the coating to the steel substrate is decreased about 3 times, from 43.58 MPa to 16.32 MPa. On the contrary, the micro-hardness of the coatings is increased about 1.7 times, from 411 HV to 701 HV. The results of the study are the basis for technologists to choose the suitable proportion of Cr3C2 and NiCr of the coatings to apply in manufacturing as well as recovering mechanical parts.
