Study on Performances of Plasma Sprayed Ceramic Coatings on Die Wear Surface

Abstract:

Microscopic observation and testing were carried out on the structure & texture, bonding form and performances of different plasma-sprayed ceramic coatings on the wear surface of Cr12MoV dies by KYKY-2800B SEM. The result indicates that the bonding between the coating and the die matrix surface is mainly of mechanical form, the bonding strength of coating is higher than that of the matrix material, the coating has a low structural porosity and the hardness and friction performance of the die surface are somewhat improved. Compared with the original dies, not only their dimensional accuracy and quality standard are no lower but also their performance such as wear resistance and corrosion resistance are better, fully satisfying the requirements of die repair & remanufacture.
