Abstract: Diamond-Like Carbon (DLC) can be slippery with a frictional coefficient on par with Teflon (e.g., 0.1). Hydrogen-terminated DLC may be more slippery than pure carbon DLC, but fluorinated DLC can be superslippery with frictional coefficient less than engine oil (0.01). The fluorinated diamond is actually superhard Teflon that may be named dialon. Dialon is not only virtually frictionless, but it is also superhydrophobic, more so than even lotus leaves. In fact, if dialon is coated onto heart valves, it will not accumulate platelets as other artificially made part will do.
Keywords: diamond-like carbon; fluorinated DLC; frictional coefficient; lotus effect; microdrills; tribology; superhard Teflon; coatings; slipperiness; dry lubricant; PCB microdrilling; PCB drilling.
