摘要: Abstract A study of the effects penetration treatments on plasma sprayed SUS316L stainless steel coatings was performed. The were sealed using multi-component oxides introduced at conditions 1273 K for 20 min, 45 min and 1373 K 45 min. effectiveness determined an electron probe microanalyzer (EPMA). results indicated that molten could seal open pores near coating surface quickly effortlessly due to good wettability. pass through oxide path connected inter micro-pores smoothly infiltrated into when period impregnation prolonged became more effective with increasing temperature because reactions between original occurred in around pores. a salt spray test treatment significantly improve corrosion resistance coating.
