style="text-indent:25px">鍍鋅層因在潮濕環(huán)境中易發(fā)生白銹腐蝕而必須進行表面防腐處理。為提高鍍鋅層的耐蝕性能,工業(yè)上常采用傳統(tǒng)的鉻酸鹽轉化技術進行處理。但鉻酸鹽具有劇毒致*性,嚴重危害人類健康和生態(tài)環(huán)境而被全世界禁止使用。因此,鍍鋅鋼表面無鉻轉化技術的研究已成為當今世界科學研究的熱點。本文采用由主鹽氟鋯酸鹽、鋅的有機緩蝕劑和輔助成膜劑組成的轉化液,在鍍鋅鋼表面開展無鉻轉化膜的制備研究。單因素試驗對轉化液組成(K_2Zr F_6、C_9H_6IO_4S、H_3BO_3)及成膜條件(p H、溫度、成膜時間)的研究結果表明,比較好成膜條件為:4g/L氟鋯酸鉀,0.06g/L7-碘-8-羥基喹啉-5-磺酸,3g/L硼酸,溫度35℃,p H=3.6,反應時間為30min。測試結果表明,轉化膜為均勻、致密的無定形結構,厚度約為8μm。由0.02%C,10.10%O,4.83%F,73.98%Zn,10.89%Zr的元素及磺酸鋅配合物組成的轉化膜使得轉化處理后的腐蝕電位從-1.252V增至-1.181V,腐蝕電位增加了71m V,腐蝕電流從1.37×10~(-5)A·cm~(-2)降至1.981×10~(-6)A·cm~(-2),腐蝕電流降低了85.5%,中性鹽霧從空白樣品的10h提高到處理后的120h,鍍鋅鋼的耐腐蝕性能**增強。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:
