3성분계 $Ti-C_x-N_{1-x}$ 코팅막은 AIP(Arc Ion Plating)법에 의해 -25V의 바이어스와 $300^{\circ}C$의 분위기에서 스테인리스 스틸 기판 위에 증착시켰다. $Ti-C_x-N_{1-x}$ 코팅막 안의 탄소(carbon)는 유입가스 비 $CH_4/(CH_4+N_2)$를 변화시키며 합성하였다. 탄소(carbon)가 증가함으로써, $Ti-C_x-N_{1-x}$ 코팅막의 미세경도는 TiN 코팅막의 20 GPa로부터 x=0.52에서 최대 약 32 GPa로 측정되었다. 또한, 미세구조는 잔류응력과 관련 있으며 탄소 함량에 따라 평균마찰계수가 크게 감소하였다.

최근 기계가공기술의 발달에 따라 내마모용 TiN 박막의 수요가 증가하였고, TiN박막은 내마모용으로 높은 경도 및 밀착력을 필요로 한다. TiN박막을 증착시키는 방법은 PVD, CVD 등 여러 가지가 있으나 본 연구에서 공구강 SKD 61기판 표면과 Radical Nitriding(RN) 처리된 SKD 61 기판에 arc ion plating(AIP)를 이용하여 TiN 박막을 증착시켜 표면경도를 향상시키고, 이 코팅층의 미세구조가 기계적 특성에 미치는 영향을 연구하였다. 그 결과 RN처리된 SKD61에서 코팅 두께가 많이 나왔고, 스크래치테스트 결과 접착력이 향상되었음을 알 수 있었다.

With different working pressures and substrate biases, Cr-Al-N coatings were deposited by hybrid physical vapor deposition (PVD) method, consisting of unbalanced magnetron (UBM) sputtering and arc ion plating (AIP) processes. Cr and Al targets were used for the arc ion plating and the sputtering process, respectively. Phase analysis, and composition, binding energy, and microstructural analyses were performed using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and field emission scanning electron microscopy (FESEM), respectively. Surface droplet size of Cr-Al-N coatings was found to decrease with increasing substrate bias. A decrease of the deposition rate of Cr-Al-N films was expected due to the increase of substrate bias. The coatings were grown with textured CrN phase and (111), (200), and (220) planes. X-ray diffraction data show that all Cr-Al-N coatings shifted to lower diffraction angles due to the addition of Al. The XPS results were used to determine the $Cr_2N$, CrN, and (Cr,Al)N binding energies. The compositions of the Cr-Al-N films were measured by XPS to be Cr 23.2~36.9 at%, Al 30.1~40.3 at%, and N 31.3~38.6 at%.

MgO thin films were deposited on glass and (100) Si substrates by an Arc Ion Plating (AIP) equipment using a magnesium metal target at various oxygen gas flow. In this work, we investigated the relationship between the structural properties and the discharge characteristics of MgO coating layers. X-ray diffraction and AFM have been used to study behaviors of the structure and surface morphology. The optical transmittance and the ion induced secondary electron emission coefficient of the MgO films have been also measured. The resistivity of the deposited MgO films was gradually increased from 0.17 G ohm/${\square}$ to 0.35 G ohm/${\square}$ with the oxygen gas flow. The growth rate of the MgO coating layer was decreased with increasing the oxygen gas flow, while the optical transmittance was improved.
