In order to determine the wear properties of AIP (Arc Ion Plating) deposition, wear process was evaluated by using a Falex test machine. Also, in order to determine the effects of coating material on the wear process, TiC, TiN, and TiCN coatings of thickness about 5 $\mu\textrm{m}$∼6 $\mu\textrm{m}$ coated by Arc ion plating deposition method were tested. The wear property was determined under a dry sliding condition as a function of the applied load, sliding distance, sliding velocity and temperature. The results show that when wear of the coating-layer occurred, specific wear amount increased with the wear rate. At initial state, the wear rate rapidly increased, but it gradually reduced as the velocity increased. Also, when raising the temperature, the wear rate increased in the order of TiCN, TiN and TiC due to the frictional heat.

Al films on cold-rolled steel sheet have been prepared by vacuum evaporation and arc-induced ion plating, respectively, and the evaporation rate and vapor distribution (thickness distribution over the substrate) have been investigated according to deposition conditions. The arc-induced ion plating (AIIP) method have been employed, which makes use of arc-like discharge current induced by ionization electrode located near the evaporation source. The AIIP takes advantage of high ionization rate compared with conventional ion plating, and can be carried out at low pressure of less than $10^{-4}$ torr. Very high evaporation rate of more than 2.0 mu\textrm{m}$/min could be achieved for Al evaporation using alumina liner by electron beam evaporation. The geometry factor n for the $cos^{n/\phi}$ vapor distribution, which affects the thickness distribution of films at the substrate turned out to be around 1 for vacuum evaporation, while it features around 2 or higher for ion plating. For the ion plated films, it has been found that the ionization condition and substrate bias are the main parameters to affect the thickness distribution of the films.

The effect of coating time in arc ion plating on surface properties of the TiN-coated high speed steel(SKH51) is 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 on the micro-hardness, the coated thickness, the atomic distribution of Ti and the adhesion strength of the SKH51 steels but that it has little influence on the surface roughness.

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.

The effect of deposition time in arc ion plating on surface properties of the TiN-coated SM45C steel is presented in this paper. The surface roughness, micro-particle, micro-hardness, coated thickness, atomic distribution of TiN, and adhesion strength are measured for various deposition times. It has been shown that the deposition time has a considerable effect on the micro-hardness, the coated thickness, and the atomic distribution of TiN of the SM45C steels but that it has little influence on the surface roughness and adhesion strength.

Compositional gradient CrNx coatings were fabricated using arc ion plating in Ar/$N_2$ gaseous mixture by gradually increasing $N_2$ flux rate from 0 to 120 SCCM. The effect of negative substrate bias on the film microstructure and mechanical properties were systematically investigated with XRD, GDOES, and SEM. The results show that substrate bias has an important influence on film growth and microstructure of gradient CrNx coatings. The coatings mainly crystallized in the mixture of hexagonal $Cr_{2}N$ and fcc CrN phases. By increasing substrate bias, film microstructure evolved from an apparent columnar structure to an equiaxed one. With increasing substrate bias, deposition rate first increased, and then decreased. The maximum of deposition rate was 15 nm/min obtained at a bias of -50V.

CrN 코팅막은 고온에서 치밀한 Cr2O3 확산방지막을 형성함으로 $800^{\circ}C$까지 기계적성질을 유지할 수 있다. 본 실험에서는 Ar, N2, 그리고 $O_2$ 가스 분위기에서 AIP(Arc Ion Plating) 기법에 의해 다양한 조성의 Cr-O-N 박막을 Si(200)과 AISI 304 기판 위에 증착되었다. Cr-O-N 코팅막은 47.4at% 미만의 산소함량을 포함 할 때까지 B1구조를 유지하였고 코팅막 내 산소함량 24.6at%에서는 강한 XRD peak intensification을 나타내었다. 47.4at%에서는 결정상을 전혀 찾아볼 수 없는 전이구조를 나타내었고, 그 이상의 산소함량에서는 Cr22O3 결정상을 나타내었다. Cr-O(17at%)-N 조성의 코팅막에서는 (200)배향의 Grain 크기 증가 및 압축잔류응력이 증가하였으나, 그 이상의 산소함량에서는 점차 감소하였다. Cr-O(24.6at%)-N 조성의 코팅막이 가장 높은 경도를 나타내었고, 산소함량이 증가할수록 점차 향상된 마찰특성을 보였다.

In this paper, effect of temperature in TiN-coating by arc ion plating on surface characteristics of a TiN coated high speed steel is investigated by experiments. Hardness, surface roughness, TiN-coating thickness and adsorption force are measured in order to evaluate the effects. For evaluation of the experimental data, one-way ANOVA method is used. It is concluded that the furnace temperature in the range $400^[\circ}C\~500^{\circ}C$ in AIP processing has a little influence on the TiN coating of the SKH51 steels.
