Effect of Coating Time on the Property of TiN-Coated Layer on High Speed Steel by Arc Ion Plating

AIP 코팅법에서 코팅 시간이 고속도강의 TiN 코팅층 성질에 미치는 영향

The effect of coating time on surface properties of the TiN-coated high speed steel(SKH51) by arc ion plating is and presented in this paper. Surface roughness, micro-hardness, coated thickness, atomic distribution of TiN and adhesion strength are measured for various coating times. It has been shown that the coating time has a deep influence more than 60 minites on the micro-hardness, coated thickness, atomic distribution of Ti and adhesion strength of the SKH51 steels, but that the coating time has little influence on the surface roughness.
