Abstract The main objectives of this research is to study the wear properties of 6061 substrate before and after Plasma treatment. Atmospheric plasma spray technique with two types of powder is used METCO 81 VS-NS (Cr-based) and METCO 447 NS (Ni-based)The aim of this work towards to investigate the quality of coating by thermal spray powder, so the following tests were performed: Microstructure and porosity. Micro hardness. Wear.Surface roughness |
