The purpose of this work is to investigate the effectiveness of PVD and CVD process of TiCN film coating on SKH51 JIS tool steel on reducing wear in piercing operation. Both processes of PVD and CVD were carried out under commercial conditions. It was found that the amount of wear found for TiCN-PVD coated punch is lower than that of CVD coated punch. Adhesive strength of film coated by CVD technique is found lower which is related to photograph taken from SEM show major adhesive wear.
