基本解释

With bright nickel strike plating before pulse non-cyanide silver plating, brighter and finer silver coatings with stronger anti-tarnish property and corrosion resistance can be obtained.
光亮镍打底后再脉冲无氰镀银，可获得更加光亮、结晶细致的镀银层，且抗变色性能及耐蚀性均增强。
Test results show that the material hase excellent wear - resistance for high temperature, hot hardness, thermal stability and tarnish resistance. It is applied to produce high quality guide.
