Study on Alloyed Surface Layer of Wear Resistant Castings by Evaporable Pattern Castings Infiltration Process

Abstract:

Wear-resistant casting was made by V-EPC infiltration process. This paper puts forward and analyses the mechanical properties and forming mechanism of the layer. The matrix material was high boron steel casting. By partial casting alloyed, the surface composite materials layer was ceramic particles, such as WC, Ferrochromium, and Borax, etc. High boron molten metal was infiltrated into the composite layer and a good cast-infiltration layer may be formed by the interaction of vacuum and high temperature. The test result shows that using this process we can get the casting surface which is special abrasion-resistance with the remarkable characteristics such as simple process and low cost. It is a new process that wear-resistant casting will be made of.
