Improved-quality needles with a diamond-like coating (DLC) for stitching machines and their production technology

摘要

It has been shown that diamond-like coatings (DLCs) can be used to improve the service and consumer properties of steel stitching needles. The DLCs were found to give the greatest improvement of the service characteristics of the needles when theroughnesses of both the outer surface of the needle and the inner surface of the needle eye were small.
