Change of the substrate surface after removal multiple plasma spraying layers

Abstract

The paper deals with the change of the surface properties of the substrate after the application of multiple plasma spraying NiCr. The influence of selected technological factors (substrate material, surface angle of the substrate and degreasing of the surface) on topography and surface quality of the substrates. Presented procedures and experimental results demonstrate surface resistance of individual materials from effect multiple plasma coatings. The best results of surface resistance have samples from chromium steel. In addition, the results of these experiments indicate which parameters are key in selecting the substrate material for the masking process in serial production of coatings by plasma spraying.
