快速选择性电镀(简称快速电镀),又称刷镀。其特点是,被镀零部件尺寸不受限制,维修工件不要拆卸搬运就可以进行修复处理。并且金属沉积速度很快,比一般槽镀要快10～20倍,电流效率比一般槽镀高3倍左右。由于这种镀法获得的镀层的孔隙率少,氢脆小,结合力牢固,结晶细微,因而被广泛地应用于各行各业。国外快速电镀的单一金属和合金的种类较多,可以进行槽电镀的金属几乎都可进行快速电镀。目前国内主要的快速镀液是铜
Rapid selective plating (referred to as rapid plating), also known as brush plating. It is characterized by the size of the parts to be plated unrestricted maintenance of the workpiece without removal can be carried out repair treatment. And the metal deposition rate is very fast, 10 to 20 times faster than normal plating, and current efficiency is about 3 times higher than normal plating. Because of this plating method obtained coating porosity, hydrogen embrittlement, strong binding, crystal subtle, it has been widely used in all walks of life. Foreign rapid plating of a single type of metal and alloy more can be slot plating of metal almost all can be rapid plating. At present, the main domestic rapid plating solution is copper
