Abstract In this research Nickel Aluminum Silicon Carbide powder was produced using ballmill for thermal spray process For this 1 Kg of mixture of powder was mixed with20 Kg steel ball and milled For determining the optimum conditions of powder forthermal spray process X Ray Diffraction XRD and Scanning Electron Microscopy SEM were employed These powders were coated on CK45 substrate by plasmaspray process in different distances and current intensities With microstructure andmorphology study of coating the optimum conditions of coating were determined Results showed that Nickel Aluminum obtained from ball mill reacted during plasmaspraying and Ni2Al3 intermetallic compound and Ni solid solution were formed Formore studies in microstructure transformation the samples were heat treated Cohesive strength of coating on substrate evaluated with Interfacial IndentationTest and then the results were compared with Cr3C2 NiCr coating Results ofmicrohardness tests showed that existing phases in plasma spray coatings Had highhardnesses
