Abstract: In this study investigated the influences of coating parameters on the mechanical properties of coatings. This study was an experimental. The AlMg3 alloy has been selected as a coated material. The Cr2O3 and Al2O3 material was selected as the coating material. Coating process was performed using the method of wire flame spray. In this process, the spray distance and thickness of the coating, the process parameters chosen (10, 12, 15 cm spray distance and 100, 200, 300 μm coating thickness). Microstructure characterization of coating structures was obtained. Images of the microstructure of the samples and micro-hardness analysis were examined. Micro-hardness results are displayed graphically. The highest hardness values for samples were obtained in 12 cm spray distance and 100 μm coating thickness.
