Effect of Oiliness Agent on Lubricity of DLC Coating

Diamond-like carbon (DLC) is used as a superior material in various fields because of its several excellent properties, such as high hardness, low friction coefficient and so on. DLC coating has good lubricity without lubricant, but it could show better lubricity by using lubricant. Therefore, we in...
