Abstarct: Copper mextal has a high heat transfer coefficient, which is why it is used in the manufacture of copper molds in continuous steel casting line and ESR molds. Due to the contact of the melt with high temperature as well as the frozen steel with the surface of the copper mold, the mold must have good corrosion and abrasion resistance. But due to their low hardness, copper alloys show low wear resistance. Due to their high hardness, high abrasion resistance, good corrosion resistance and acceptable toughness, mextal-ceramic composite coatings are often applied to the surface by one of the methods of plating, thermal spraying and laser to improve tribological and corrosion properties. In this project, the tribological behavior of NiCrBSi-Cr3C2 thermal spray coatings on copper substrate was investigated. The results showed that the different coatings created on the copper substrate were completely dense, uniform and almost free of porosity, pores and oxide particles. By adding and increasing the amount of chromium carbide in the NiCrBSi coating, the porosity decreased and the hardness significantly increased. On the other hand, with the addition of chromium carbide to the NiCrBSi coating, the surface hardness increased significantly more. By adding 10, 20 and 30% chromium carbide to the baxse coat, the surface roughness and fracture toughness increased. The results of the abrasion test showed that the weight loss of the samples during the abrasion test was significantly reduced by adding chromium carbide to the NiCrBSi coating at all distances. Also, the wear rate for samples with chromium carbide reinforcing particles was significantly lower than NiCrBSi coating, and on the other hand, the amount of friction decreased with increasing the amount of chromium carbide in the coating. By applying the coating on the copper substrate, the oxidation resistance of the samples increased and also by adding chromium carbide reinforcing particles to the NiCrBSi coating, the coating oxidation resistance increased. So that the copper substrate was severely damaged and the coating laxyer of the samples was not damaged much. Also, with increasing the percentage of chromium carbide in the coating, the amount of coating degradation almost decreased and at all temperatures, the amount of coating degradation was very small compared to the copper substrate.
