Abstract:In order to improve the quality of spinneret used in chemical fiber spinning，the advantages and disadvantages of three kinds of spinnerets made of gold-platinum alloy， tantalum and stainless steel are introduced.Taking PY35-2050-0.075 spinneret made of SUS316L stainless steel  as an example，the properties，quality and surface morphology of the spinnerets before and after DLC film coating are compared by salt spray test and acid solution immersion test.It is pointed out that the bonding strength between DLC film by vapor deposition and stainless steel spinneret matrix can be improved by using Cr+WC as the intermediate transition layer.For DLC film coated stainless steel spinneret，the hardness is up to 2000 HV，the strength and acid and alkali corrosion resistance are better than ordinary stainless steel spinneret.DLC film coated stainless steel spinneret has long service life，and is more suitable for high temperature，high pressure and acid and alkali corrosion spinning environment.
Key Words:spinning；spinneret；stainless steel；DLC film；vapor deposition；hardness；corrosion resistance
