Thermophysics and Aeromechanics Aims and scope

Abstract

An approach to the modeling of the process of the formation of a lamellar structure of thermal coatings, including plasma coatings, at the spraying of metal powders is proposed. The results are presented, which concern the development of the computational algorithm and the program complex for modeling the process of laying the splats in the coating with regard for the topology of its surface, which varies dynamically at the spraying, as well as the formation of a lamellar structure and porosity of the coating. The experimentally verified theoretical solutions are used to predict the scenarios of the formation of splats and rapid prediction of their thicknesses and diameters. The results of computational experiments illustrating the performance of the developed computational technology are presented.
