Abstract

Abstract: Punched by needle, spinneret is a critical component of chemical fiber production equipment. Increasing order and short lifetime of punching needle seriously drags the production schedule of enterprise. W-DLC (wolfram-doped diamond-like carbon) film was deposited on the needle in a magnetron sputtering system, and the doping content of wolfram was controlled by adjusting the ratio of Ar to C2 H2 . A systematic investigation was conducted on the structural and punching performances of the coated needle. The results show that, (1) W-DLC film has a dense structure, and W element exists in phase of W1-X C. (2) W-DLC film plays an important role of the needle protection, and can prolong its lifetime in evidence. (3) W-DLC film coated punching needles can punch up to 6000 times per needle, and its lifetime can be increased to about 200% in the production line.
