AbstractIn this study, the surface of EN 10130 steel used in deep drawing processes in industry is coated with CMT technique. Al2O3 powder with different ratios of Al, Zn, Sn and Ni metal powders were used as coating material. Nano-sized metal powders and ceramic powders were used. This coating has been made to improve wear and corrosion resistance after deep drawing of EN 10130 steel. However, due to the lack of sufficient time for the operation and the failure of the wear device, only SEM and EDX studies were applied. In SEM studies, it was observed that the Al2O3 + Ni composition and the coating interface were not smooth. Other coating surfaces are in good condition. Although the average coating thickness varies regionally, it is 20-60 µm thick.
