4.Moreover, it was feasible to reduce the oxidation of the alkynol brighter by choosing active nickel as the anode in the bright nickel electroplating.
选择活性镍作为光亮镍阳极,可以减少炔醇类光亮剂的氧化。
5.At present, trivalent chromium electroplating process has became one of the mostimportant techniques to taking place of the seriously pollutional hexvalent chromiumelectroplating process.
目前,三工艺已经成为取代重污染六的最重要技术之一。
6.The results show that the failure is mainly attributed to the inappropriate heat-treatment technology of the locking nut and the hydrogen brittlement from electroplating of the stopping pad.
