在钢铁制品上应用化学方法镀镍,不少的资料曾有过详细介绍,但是对于在铜件上应用化学镀镍,还没有找到很具体的资料。我厂产品有不少铜制零件要求镀镍,如应用电镀镍,则由于零件不大,而且形状复杂;譬如有一种铜制零件要求内孔镀镍,内径只有4～5公厘,而长度有50公厘,其中有一段还有螺纹,镀镍后的尺寸要求很嚴格(要正好与另一个零件滑合),用电镀镍达到上述要求是很困难的。另外,电镀镍的操作技术也很难控制。如我厂有一个铜零件镀镍后,在装配时要反复弯折数
The application of chemical nickel plating on steel products, many of the data have been described in detail, but for the application of electroless nickel plating on copper, have not found very specific information. I plant a lot of copper products require nickel plating, such as the use of nickel plating, the parts are not large, but the shape is complex; for example, a copper parts require nickel-plated hole, the inner diameter of only 4 to 5 mm, while the length There are 50 mm, of which there are still some thread, the size of the nickel plating is very strict (to just slip with another part), with nickel plating to achieve the above requirements is very difficult. In addition, the operation of nickel plating is also very difficult to control. If I plant a copper parts after nickel plating, the number of bending in the assembly to be repeated
