自润滑热镀锌汽车板的性能分析

Analysis on properties of self-lubricating hot-dip galvanized steel sheet applied to automobile

在热镀锌汽车板表面涂覆无机自润滑涂层后对材料的成型性能、焊接性能、胶接性能、耐蚀性能等进行分析。结果显示,自润滑膜能够在冲压过程中对锌层提供较好的保护,从而有效提升热镀锌板的成型性能。自润滑热镀锌汽车板的耐蚀性能、连接性能等均能够满足汽车主机厂的相关认证要求。

The formability, weldability, adhesive bondability and corrosion resistance of hot-dip galvanized steel sheet ~br automobile covered by inorganic self-lubricating film were analyzed. It is indicated that the self-lubricating film offers an efficient protection for zinc coating during the stamping process, improving the formability of hot-dip galvanized steel sheet. The corrosion resistance as well as the weldability, bondability and other properties of the self-lubricating hot-dip galvanized steel sheet for automobile meet the corresponding certification requirements of automobile manufacturers.
