Mechanism of Diamond-Like Carbon (DLC) Delamination under Rolling Contact Condition

Diamond-like carbon (DLC) is being advanced as an excellent surface modification technology for a growing number of applications because of its low friction coefficient and excellent wear resistance. Due to the excellent characteristics of certain mechanical elements, such as a bearing, high levels...
