Purpose: Plasma spraying is one of the basic methods of coating deposition used in many branches of industry, especially in aviation and power industry. The process is applied in the aircraft engineering for obtaining the sealing coats, anti-abrasive coatings and, above all, metallic layers, ceramic layers as well as thermal barrier coatings. The comprehensive characterisation of the plasma spraying process requires taking into consideration 50-60 parameters, which confirms its complexity. The purpose of this article is to describe the functioning of the program, presentation of its simulation capabilities, including the parameters of the plasma spraying process, which can be controlled in the program. Design/methodology/approach: The authors present in the article the model of plasma spraying process and describe the simulation of the process with a use of Jets&Poudres software. It is based on the GENMIX code (GENral MIXing) developed by B. Spalding and S. Patankar for analysis of the two-dimensional, parabolic flows characterized by large values of Reynolds and Péclet number. Findings: Jets&Poudres enables tracking the current position, velocity and the fusion process of powder particles as well as conducting the basic analysis of obtained coating formed during the plasma spraying process. Practical implications: Jets&Poudres enables determination of parameters of plasma spraying process in order to obtain better coating thickness distribution and improve the coating efficiency - ratio between the weight of the spray pattern deposited on a big flat plate and the weight of powder injected. Originality/value: Jets&Poudres is one of few available tools based on comprehensive model of plasma spraying under atmospheric pressure which makes possible to perform simulation of the whole process.
