AIP-TiN 코팅에서 증착시간이 SKH51과 SKD11 강의 표면특성에 미치는 영향에 관한 비교 연구

Comparative Study on Effect of the Surface Characteristics of the SKH51 and SKD11 Steels with Deposition Times by AIP-TiN Coating

In this paper, the surface characteristics of the AIP-TiN coated of the SKH51 and SKD11 steels under various deposition times are presented with emphasis on the comparison of the two materials. The micro-particle, the surface roughness, the micro-hardness, the coated layer thickness, the atomic distribution of Ti, N and Fe elements and the adhesion are measured for various deposition times. It has been shown that the micro-particle, the surface roughness, the coated layer thickness and the atomic distribution of Ti, N and Fe elements are similar for the two cases regardless of the test deposition time from 10 to 180 minutes. However, it has been shown that the micro-hardness and the adhesion of the SKH51 steel are higher than the SKD11 steel, indicating that they are much affected by the hardness of the material to be coated.
