Defining efficient modes range for plasma spraying coatings

The article outlines an approach for ensuring the quality of wear-resistant plasma coatings of high-chromium powder material. Based on the results of theoretical and empirical research, the authors received a plasma coating process model, which takes into account the influence of spraying modes on the main indicators of quality: adhesive strength, porosity, and the level of residual stresses. The authors recommend relevant functional dependencies, which enable determining the combination of the process mode parameters to ensure efficient indicators of the plasma coating quality. (paper)
