Özet

In 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.
