PRODUCTION OF SPINDLE DISK FOR SPINNERET USING PLASMA SPRAYING

摘要

PURPOSE: A process for preparing a spindle disk for spinneret by manufacturing a spindle disk after the CNC processing using aluminium and forming a ceramic coating on an outer circular surface using plasma spraying is provided, thereby improving quality of a spindle disk and reducing the cost of production by recycling ceramic coating. CONSTITUTION: A spindle disk is prepared by forming a ceramic coating on an outer circular surface of the spindle disk using plasma spraying after the production of a spindle disk by computer numerical control processing using aluminium under conditions of an amount of argon gas of 80 SCHF, an amount of hydrogen of 10 to 25 SCHF, a power output of 30 to 40kW, 50A and a spraying distance of 60 to 90mm.
