生产摩托车启动臂，在表面电镀后出现脱皮现象--[请教]
<P>各位好！</P><P>我公司生产摩托车启动臂（脚启动时蹬的那个件），现在我遇到一难题，在表面电镀（三镍铬，且加入纳米技术）后出现附着力不好的情况，用锉刀检验时出现脱皮现象，严重的出现整块整块的脱落。后来进行了一个补救措施：用300度的温度进行烘烤3小时后，脱皮现象明显好转，附着力OK了，我多次到电镀厂（我公司的外协单位）查看，但我又不是专业搞表面处理的，我也分析不也来具体问题出在哪里。反正电镀在前处理（<FONT size=1><SPAN style="FONT-SIZE: 14pt; FONT-FAMILY: 宋体; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'">“三碱</SPAN><SPAN lang=EN-US style="FONT-SIZE: 14pt; FONT-FAMILY: 'Times New Roman'; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-fareast-font-family: 宋体">”,</SPAN><SPAN style="FONT-SIZE: 14pt; FONT-FAMILY: 宋体; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'">（磷酸三钠</SPAN><SPAN lang=EN-US style="FONT-SIZE: 14pt; FONT-FAMILY: 'Times New Roman'; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-fareast-font-family: 宋体">-Na3PO4</SPAN><SPAN style="FONT-SIZE: 14pt; FONT-FAMILY: 宋体; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'">、片碱</SPAN><SPAN lang=EN-US style="FONT-SIZE: 14pt; FONT-FAMILY: 'Times New Roman'; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-fareast-font-family: 宋体">-NaHO</SPAN><SPAN style="FONT-SIZE: 14pt; FONT-FAMILY: 宋体; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'">、纯碱</SPAN><SPAN lang=EN-US style="FONT-SIZE: 14pt; FONT-FAMILY: 'Times New Roman'; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-fareast-font-family: 宋体">-Na2CO3</SPAN><SPAN style="FONT-SIZE: 14pt; FONT-FAMILY: 宋体; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'">），比例为</SPAN><SPAN lang=EN-US style="FONT-SIZE: 14pt; FONT-FAMILY: 'Times New Roman'; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-fareast-font-family: 宋体">1</SPAN><SPAN style="FONT-SIZE: 14pt; FONT-FAMILY: 宋体; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'">：</SPAN><SPAN lang=EN-US style="FONT-SIZE: 14pt; FONT-FAMILY: 'Times New Roman'; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-fareast-font-family: 宋体">1</SPAN><SPAN style="FONT-SIZE: 14pt; FONT-FAMILY: 宋体; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'">：</SPAN><SPAN lang=EN-US style="FONT-SIZE: 14pt; FONT-FAMILY: 'Times New Roman'; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-fareast-font-family: 宋体">1</SPAN></FONT>）、光亮剂、PH（<SPAN lang=EN-US style="FONT-SIZE: 14pt; FONT-FAMILY: 'Times New Roman'; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-fareast-font-family: 宋体">3.5</SPAN><SPAN style="FONT-SIZE: 14pt; FONT-FAMILY: 宋体; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'">～</SPAN><SPAN lang=EN-US style="FONT-SIZE: 14pt; FONT-FAMILY: 'Times New Roman'; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-fareast-font-family: 宋体">3.8</SPAN>）值等方面都想了办法，还是没有明显的改善。望各位高手帮忙！谢谢！</P>

这种现象在常规电镀中也是常有的事，一二句话难说清楚。其中某一道工序出现问题就有此现象。比如前处理，电解液的成份，温度，电流密度，清洗等。问题出现最多的是光亮剂。Re: 生产摩托车启动臂，在表面电镀后出现脱皮现象--[请教]
我们在生产中也遇到类似的问题．只能和外协单位多协调沟通，看有什么好方法．质量也不是很稳定．Re: 生产摩托车启动臂，在表面电镀后出现脱皮现象--[请教]
电镀前没处理好 一电镀前清洗不干净二电镀工艺问题(电镀厂解决)
三,打底电镀素材太薄,表面电镀素材太厚.(打底素材太薄会影响到附着力)
