Tribological properties of DLC coatings and comparison with test results: Development of a database

Deposition and properties of Al-containing diamond-like carbon films by a hybrid ion beam sources

“…Diamond-like carbon (DLC) films have potential widespread applications in many industrial fields of cutting tools and dies, magnetic data storage, micro-electromechanical devices (MEMS) due to their outstanding properties, such as high hardness, low friction coefficient, good corrosion-resistance, and smooth surface [1][2][3]. However, the existence of the high internal stress in the films leads to poor adhesion to the substrate, and limits the extended utilization of DLC films [4][5][6][7].…”

Gross slip fretting wear performance of a layered thin W-DLC coating: Damage mechanisms and life modelling

“…The doping of DLC coatings with a wide range of different metals has been shown to lead to changes in their mechanical properties (lower internal stress and hardness, improved adhesion) as well as in their tribological properties [7,8]. However, the inability of DLC coatings to follow the elastic and/or plastic deformation of substrates without failing (brittle fracture) has been a major disadvantage.…”

The Effect of Nitriding/DLC Coating on the High Cycle Fatigue Properties of Fe-3.0Ni-0.7Cr-1.4Mn-X Steel

“…우수한 제품을 생산하기 위해서 경 면성과 내마모성을 동시에 만족시키는 금형 표면처 리 및 코팅 기술의 개발이 필요하다. 따라서 금형 의 내마모성 향상을 위해 침탄 및 질화와 같은 표 면 경화 처리나 TiN, CrN, WC, DLC와 같은 경질 코팅 방법이 있으며 [3][4][5][6][7][8], 최근에는 TiAlN, TiCN, TiAlCN, CrN, WC/C 등 다양한 경질 박막과 복합 코팅을 이용한 접착력과 내마모특성 향상에 관한 연구가 활발히 진행되고 있다 [9][10][11][12][13]. Avelar-Batista 와 동료들의 연구 [14]에서는 TiN, CrN과 DLC 코 팅을 증착한 Ti-6Al-4V합금의 내마모성이 향상되었 다고 보고하였고, Silva와 동료들은 TiAlSiN과 CrN/ CrCN/DLC 복합 코팅이 금형의 내마모성을 향상시 켰다는 연구를 보고한 바 있다 [15].…”
