铝件上镀什么可导电并防止氧化?---[请教]
请教各位,铝件上面镀什么东西即可以导电又可防止氧化?谢谢!!Re: 铝件上镀什么可导电并防止氧化?---[请教]
没怎么听说铝可以电镀的一般情况下是氧化处理的

我听说铝上可以镀铜或银,不知哪位有这方面资料,请帮忙!!Re: 铝件上镀什么可导电并防止氧化?---[请教]
铝可以电镀,但在镀前要使表面产生一中间层。一般用锌置换法。流程如下:弱碱除油/水洗/阴极电解除油/水洗/锌置换/水洗/闪镀铜。。。

我们这一般都是铝本色氧化,或者是镀锌Re: 铝件上镀什么可导电并防止氧化?---[请教]
谢谢4楼5楼,再问5楼铝氧化后还导电吗?Re: 铝件上镀什么可导电并防止氧化?---[请教]
铝氧化后,有的可以导电,有的不导电。看你要求了。化学氧化,阳极氧化工艺都不一样的。

可先镀铜,再镀银.可有较好的导电性,温升不高Re: 铝件上镀什么可导电并防止氧化?---[请教]
我一般都是镀镍的Re: 铝件上镀什么可导电并防止氧化?---[请教]
