Abstract
In order to improve wear resistance of microextrusion dies with numerous imperceptible holes, DLC film was deposited on the inner wall surface of model dies with holes of 2 mm, 0.9 mm in diameter and 20 mm in depth by using pulse plasma-enhanced CVD method. It was clearly shown that depth of the DLC film deposited on the inner wall surface of the dies was increased with the increasing of deposition pressure from 3 Pa to 10 Pa.
