测试金瓷结合强度。
目的：研究非贵金属合金在上瓷前经过不同的阳极钝化条件处理及除气、预氧化对金瓷结合强度的影响。
Objective: This study is to determine the effect of different surface anodizing and degassing-preoxidation on bonding strength of porcelain to Ni-Cr alloy.
在相同的预氧化时间的条件下，金-瓷结合强度随除气时间延长也呈递减趋势。
When the time of preoxidation was same, the combining intensity of alloy-porcelain decreased with the time prolonging of degassing.
目的：金瓷修复体成功的关键是金属与瓷之间要获得良好的结合强度。
Objective: The key of the success of porcelain-fused-to-metal restoration(PFM) is to obtain better bond strength between metal and porcelain.
结论自制镍铬钛烤瓷合金的金瓷结合良好，剪切结合强度可以达到临床应用的要求。
ConclusionThe shear bond strength of the self-made Ni-Cr-Ti porcelain alloys all can satisfy the clinical requirements.
