tarnish resistance

基本解釋

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.
光亮鎳打底后再脈沖無(wú)氰鍍銀，可獲得更加光亮、結(jié)晶細(xì)致的鍍銀層，且抗變色性能及耐蝕性均增強(qiáng)。
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.
試驗(yàn)結(jié)果表明，該材料具有優(yōu)良的高溫耐磨性、熱強(qiáng)性、熱穩(wěn)定性及抗氧化性能，是適用于制作優(yōu)質(zhì)導(dǎo)衛(wèi)板的材料。
