Tribological and dry drilling performance of WS2/Cr-AlCrN coatings
Dry drilling gives a higher request to the anti-friction property of cutting tools. However, most tool coatings commonly have less lubricant effect. In present paper, WS2/Cr layer was deposited on AlCrN layer by a radio frequency magnetron sputtering ...
