| Abstract: | The effects of process conditions on the deposition rate,appearance,adhesion strength,anti-tarnish property and surface morphology of the silver coating obtained from a nicotinic acid bath by pulse reverse plating were studied.Under optimal conditions,the above-mentioned process was compared with the butanediimide silver plating process.The results showed that bright deposit with good anti-tarnish property can be obtained by the given pulse reverse process at a current density of 0.25 A/dm~2, frequency 1 00... |
