Abstract:In order to enhance the surface performance of some key parts, the technology of thermal spraying is often used in practice. By spraying super alloy powder on the surface, the parts can get good resistance to wear, corrosion and high temperature, but how to machine these parts has become a difficult problem in production. In this paper, the cutting performance of two kinds of super alloy with thermal sprayed coatings (FZNCr-60A and BKHA) is systematically studied through some turning experiment. According to the comparison of cutting force in using different kinds of blades in the turning experiment, it is found that the better effect can be got by using the blade with bigger rake angle to turn the relative coating materials. On the basis of orthogonal turning experiment, the cutting force under the different cutting parameters has been measured, the changing rule of cutting force has been analyzed, and the empirical formula of cutting force has been presented. By summarizing the effect of cutting parameters and other factors to the turning performance of these materials, it will provides useful reference for cutting these kinds of super alloy with thermal sprayed coatings in production.
