摘要： 目的探讨用磁控溅射涂层作为钛与瓷间的中间层,增强钛／瓷结合强度的可行性。方法对钛试件表面采用4种不同方法(磨光、磨光后磁控溅射CrTiAlN梯度涂层、喷砂、喷砂后磁控溅射CrTiAlN复合涂层)处理后,测试钛试件表面硬度及涂层厚度,对表面进行Duceratin瓷粉烧结。根据ISO9693标准,对钛／瓷间的三点弯曲结合强度进行测试,并对钛／瓷结合界面和瓷剥脱面进行SEM／EDS观察与分析。结果磨光组和喷砂组涂层处理厚度一致,涂层处理可使钛表面硬度显著提高;磨光涂层组钛／Duceratin瓷结合强度显著大于磨光空白组(P<0．01),喷砂涂层组钛／瓷结合强度和喷砂空白组无统计学差异(P>0．05)。喷砂空白组、喷砂涂层组钛／瓷结合强度显著大于磨光涂层组(P<0．05)。磨光空白组钛瓷界面可见连续且较宽的裂隙;磨光涂层组可见钛瓷结合较好,界面散在不连续的点块状裂隙;喷砂空白组钛瓷界面结合较好,无明显裂隙;喷砂涂层组钛瓷结合良好,钛表面凸凹不平,与瓷相互嵌合。结论钛表面磁控溅射CrTiAlN梯度涂层在光滑钛表面可有效地提高钛／瓷结合强度,磁控溅射涂层是一种有前景的钛瓷界面中间层

Abstract: Objective To study the feasibility of magnetron sputtering Cr-Ti-Al-N complex coating as an interlayer on titanium to enhance the titanium-ceramic binding strength. Methods With a three-point bending test according to ISO 9693, the binding strength of Duceratin (Degussa) to titanium substrate prepared with 4 different surface treatments (polishing, polishing and megnetron sputtering Cr, Ti, Al, and N complex coating, sandblasting, sandblasting and coating) was evaluated. Ti/porcelain interface and fractured Ti surface were examined using scanning electron microscopy with energy-dispersive spectrometry (EDS). Results The binding strength of polished and coated titanium/Duceratin was significantly higher than polished titanium group (P<0.05). The binding strength of sandblasted and coated titanium/Duceratin did not differ significantly from that of sandblasted titanium group (P>0.05), and the strength in the two sandblasted titanium groups was significantly higher than that in polished and coated titanium group (P<0.05). Conclusion Megnetron sputtering Cr-Ti-Al-N complex on polished titanium can increase the titanium/porcelain binding strength. Megnetron sputtering coating is a promising Ti/porcelain interlayer.
