Fine-tuning of these …
WebJul 31, 2000 · In sliding friction of hard coating such as diamond or DLC against softer material of metal or ceramic, friction coefficient tends to be high since asperities on the coating surface work as abrasive ones. It varies from 0.4 to 0.05, in the cases of diamond and DLC coatings depending on their roughness [15]. Webcoefficient of friction, ratio of the frictional force resisting the motion of two surfaces in contact to the normal force pressing the two surfaces together. It is usually symbolized by the Greek letter mu (μ). Mathematically, μ = F / N, where F …
