本研究的目的是研究氧化铝喷砂和酸蚀的实验表面处理对两种树脂复合材料与商业纯钛之间的结合强度的影响。钛表面用氧化铝喷砂，然后用45wt% h2so4和15wt% HCl （H2SO4-HCl）蚀刻。光固化和热固化树脂复合材料（Estenia）和光固化树脂复合材料（Ceramage）与辅助金属底漆一起使用。贴面试件在4 ~ 60℃范围内进行5万次热循环，并测定剪切粘结强度。爆破/H2SO4‐HCl/Estenia的粘结强度最高（30.2±4.5 MPa），爆破/Etching/Ceramage的粘结强度最高（26.0±4.5 MPa），爆破/No Etching/ Estenia的粘结强度次之（20.4±2.4 MPa），爆破/No Etching/Ceramage的粘结强度为0.8±0.3 MPa。扫描电镜观察显示，氧化铝爆破和H2SO4-HCl蚀刻在钛表面产生了许多微纳米级的空腔，这有助于粘接。
The purpose of this study was to investigate the effect of an experimental surface treatment with alumina blasting and acid etching on the bond strengths between each of two resin composites and commercially pure titanium. The titanium surface was blasted with alumina and then etched with 45wt% H2SO4and 15wt% HCl (H2SO4–HCl). A light‐ and heat‐curing resin composite (Estenia) and a light‐curing resin composite (Ceramage) were used with adjunctive metal primers. Veneered specimens were subjected to thermal cycling between 4 and 60°C for 50,000 cycles, and the shear bond strengths were determined. The highest bond strengths were obtained for Blasting/H2SO4‐HCl/Estenia (30.2 ± 4.5 MPa) and Blasting/Etching/Ceramage (26.0 ± 4.5 MPa), the values of which were not statistically different, followed by Blasting/No etching/Estenia (20.4 ± 2.4 MPa) and Blasting/No etching/Ceramage (0.8 ± 0.3 MPa). Scanning electron microscopy observations revealed that alumina blasting and H2SO4–HCl etching creates a number of micro‐ and nanoscale cavities on the titanium surface, which contribute to adhesive bonding.
