Abstract. Thermal Spray coatings are used in the automotive industry, with multiple applications, offering effective protection solutions in the suspension system, transmission and engine components. Plasma jet deposition may be a solution to classical methods of enhancing wear resistance by chemical or thermochemical treatments in main and crankpin journals. Through this study the deposition of layers on the surface of a C45 steel was analyzed, using the following powders: Cr3C2- (Ni20Cr), Al2O3-13TiO2, Cr2O3-SiO2-TiO2. Powders were deposited with the 9MCE Spraywizard at atmospheric pressure. Microstructural and morphological analyzes were performed by means of optical, electronic and X-ray diffraction microscopy. Microstretch and indentation tests were performed to determine the adhesion of the deposited layer to the base material. As a result of the tests, the layer deposited using the Al2O3 13TiO2 powder has higher hardness characteristics than the layers of Cr3C2- (Ni20Cr) and Cr2O3-SiO2-TiO2 powders and that of the base material. This study confirms that plasma jet deposition is an effective solution to classic methods used to increase crankshaft wear resistance, at least in limited production series.
