Reparation of Paper Dryer by Arc-sprayed 1Cr18Ni9Ti Stainless Steel

A wear-corroded paper dryer was repaired with arc-sprayed 1Cr18Ni9Ti stainless steel.The coating performance of the repaired paper dryer was studied.An optimum arc-spraying technology for repairing paper dryer was obtained through orthogonal experiment as follows:arc current 230 A,spraying distance 220 mm,arc voltage 35 V and air pressure 0.8 MPa.
