    摘要:

    為提高口腔醫(yī)學(xué)領(lǐng)域用純鈦鑄件的表面性能，改善其美觀效果，用輝光等離子氮化、脈沖電弧離子鍍涂層復(fù)合處理純鈦鑄件，使用掃描電鏡、接觸角測量系統(tǒng)及X射線衍射分析儀評價其表面性能及晶相結(jié)構(gòu)組成，再用分光測色計分析其色彩學(xué)特征。結(jié)果表明，純鈦鑄件等離子氮化、鍍氮化鈦涂層復(fù)合處理后表面形成均勻穩(wěn)定的TiN復(fù)合梯度涂層；人工唾液在復(fù)合處理試件表面的接觸角 (60.29±2.00)°明顯小于純鈦 (73.12±3.29)°；顏色均勻美觀，在CIE表色系中L*：61.22±0.455、a*：1.84±0.055、b*：25.66±0.219，呈金黃色，表面晶相結(jié)構(gòu)以耐磨性較好的TiN、Ti2N為主。

    Abstract:

    Plasma nitriding combined with pulsed bias arc ion plating was employed to treat cast pure titanium (PT) used as a kind of medical and dental materials in order to improve the surface properties and to obtain better the color stability. The morphology and phase structure of the modified layer were analyzed using XRD and SEM. The contact angle and color of the samples were studied after ion nitriding/TiN-coated compound treatment (compound nitriding, CN) by Easy Drop Standard and spectraphotometer, respectively. The results show that a composite gradient TiN coating, which is uniform, stable and dense, is formed after CN. The contact angle of the artificial saliva on samples treated by CN (60.29±2.00)° is obviously lower than that of the untreated PT samples (73.12±3.29)°. And the color of CN samples with L*: 61.22±0.455, a*: 1.84±0.055, b*: 25.66±0.219 in CIE-1976- L*, a*, b* colorrange system is bright and golden. The main phases on the specimen surface are TiN and Ti2N with good wear resistance.
