一、金属涂镀技术在国外的发展涂镀工艺是在电镀、刷镀、接触镀,修理镀等老工艺的基础上,进一步试验研究发展起来的新工艺。这种新技术的工艺方法原理与电镀相似,但取消了电镀槽,实现了“无槽电镀”。它在老的电镀工艺上,三方面有较大的突破,即溶液、电源及涂镀工具。 First, the development of metal coating technology in foreign countries Tu coating process is electroplating, brush plating, contact plating, plating and other old repair process, based on further experimental research and development of new technology. The technology of this new technology is similar in principle to electroplating process, but the electroplating bath is canceled and the “slotless electroplating” is realized. It is in the old plating process, there are three major breakthroughs, namely, solution, power and coating tools.
