OBJECTIVE
The aim of this study was to establish sol-gel technique of coating titanium on the surface of Ni-Cr alloy (PFM) in order to enhance corrosion resistance and reduce corrosive rate in oral cavity.
METHODS
The sol-gel technique included four steps: (1) pre-treatment; (2) preparation of sol; (3) coating; (4) heat treatment. Elements on the surface of Ni-Cr alloy were analyzed with X-ray photoelectron spectroscopy.
RESULTS
After coating Ti, the surface of Ni-Cr alloy looked light golden without particles, blisters and fragments. Besides Ni and Cr, titanium was found on surface of Ni-Cr alloy after coating. With Ar(+) ion carving-corrosion figure, the thickness of titanium was about 20 - 80 microm.
CONCLUSION
With sol-gel technique, titanium could be coated on the surface of Ni-Cr alloy.
目的
本研究旨在建立在镍铬合金（烤瓷熔附金属）表面涂覆钛的溶胶 - 凝胶技术，以增强其耐腐蚀性并降低在口腔中的腐蚀速率。
方法
溶胶 - 凝胶技术包括四个步骤：（1）预处理；（2）溶胶制备；（3）涂覆；（4）热处理。用X射线光电子能谱分析镍铬合金表面的元素。
结果
涂覆钛后，镍铬合金表面呈浅金色，无颗粒、水泡和碎片。涂覆后，在镍铬合金表面除了发现镍和铬外，还发现了钛。通过氩（+）离子刻蚀 - 腐蚀图像，钛的厚度约为20 - 80微米。
结论
采用溶胶 - 凝胶技术可在镍铬合金表面涂覆钛。
