【摘要】：研究了熱浸鋅鋼板的硅酸鹽體系無鉻鈍化工藝。通過硫酸銅點(diǎn)滴試驗(yàn)及電化學(xué)工作站測(cè)試鈍化膜的耐蝕性。結(jié)果表明:在pH=12、θ=70℃,t=15 min的條件下所得鈍化膜的耐蝕性較好。
[Abstract]:The chromium-free passivation process of hot dip galvanized steel plate in silicate system was studied. The corrosion resistance of the passivated film was tested by copper sulfate drop test and electrochemical workstation. The results show that the passivation film has good corrosion resistance at pH 12, 胃 ~ (70 鈩，
