摘要
目的:探讨镍铬合金表面不同涂镀层的抗腐蚀性能。方法:将4种涂镀层镍铬合金试件,分别浸泡在中性人工唾液2个月、酸性人工唾液20d。结果:在中性和酸性人工唾液中,镍铬合金表面涂镀的氮化钛膜、电镀金膜、金泥涂层及金瓷涂层,都表现出良好的耐腐蚀性能。结论:在相同的人工唾液环境中,不含铍镍铬合金比含铍镍铬合金具有更佳的耐腐蚀性能。
Objective： Doing contrastive research on corrosion resistance of Ni-Cr alloy with different coatings. Method： The corrosion resistance of the Ni-Cr alloy with the four coatings were qualitatively and quantitatively studied by immersing into the natural artificial saliva two months and acidic artificial saliva twenty days. Result： Titanium nitride （TIN） film, gold electroplating layer, gold paste and gold-ceramic compound showed good corrosion resistance.Conclusion：The corrosion resistance of Ni-Cr alloy Ⅰ is more than Ni-Cr alloy Ⅱ in the natura and acidic artificial saliva.
