膜厚对自润滑合金化板性能的影响研究

摘要

对不同膜厚自润滑合金化板的润滑性能、成形性能、焊接性能、脱脂性能进行了研究。结果表明：随着膜厚增加，自润滑合金化板的润滑性能、成形性能提高，焊接性能、脱脂性能变差；膜厚小于300mg／m2时，成形性能提高的不明显；膜厚大于500mg／m2时，焊接性能及脱脂性能受到不良影响。为保证自润滑合金化板的性能，生产时应将自润滑膜厚控制在300mg／m2～500mg／m2。%The lubricating property ,formability ,weldability and degreasing performance of the self-lu-bricated galvannealed steel sheet with different thickness of self-lubricated coatings were studied in this pa-per .The results showed that as thickness of self-lubricated coating increased ,the lubricating property and formability of the self-lubricated galvannealed steel sheet was better ,while the weldability and degreasing performance was worse .When the thickness of self-lubricated coating was less than 300mg/m2 ,the im-provement of formability was not obvious .While it's greater than 500mg/m2 ,the weldability and degrea-sing performance started to turn bad .T he thickness of self-lubricated coating should be controlled in 300~500mg/m2 to ensure the properties of the self-lubricated steel sheet .
