Performance Evaluation of Thermal Spraying Coatings Based on Microstructure

Abstract:

At present, the performance evaluation of thermal spraying coating mainly depends on experimental test and numerical calculation, but due to the limitation of error and algorithm, neither of the two algorithms can effectively satisfy the effective evaluation of thermal spraying performance. In this paper, taking WC/Co coating as an example, a new method for calculating the performance parameters of thermal spraying coatings is proposed, that is, the finite element model and the analysis model of coating parameters are established for the microstructure of the coatings under different magnification, respectively. By calculating the basic performance parameters of the coatings, the macro performance parameters of the thermal spraying coatings are obtained, so that the performance of the coatings can be evaluated.
