Abstract

The present study investigated the influence of surface treatments of composite materials using 6% hydrofluoric acid or 2% acidulated phosphate fluoride, the influence of the application of a bonding agent to the surface, and the influence of incremental curing of composite materials on the shear bonding strength between composite materials and resin cements. These results were studied statistically by analyzing variances in three-way classification and by their contributory ratios. The effects of hydrofluoric acids or acidulated phosphate fluorides on the treated surfaces of composite materials, and also the interfaces between composite materials and resin cements were further examined by mean of scanning electron microscopy (SEM). Unlike the controls, surfaces of all specimens treated with hydrofluoric acid or fluoride revealed micro-porous surfaces, but the effect of the surface treatment on the bonding strength was not equal for all the composite materials tested. The application of a bonding agent influenced some composite material, but the incremental curing of composite materials had no influence on bonding with resin cements.

不同处理对复合材料与树脂胶结物粘结的影响。

本研究考察了6%氢氟酸和2%酸化氟化磷酸对复合材料表面处理的影响、表面粘结剂的应用以及复合材料增量养护对复合材料与树脂水泥剪切粘结强度的影响。通过分析三向分类的方差及其贡献率，对这些结果进行了统计研究。采用扫描电子显微镜(SEM)进一步研究了氢氟酸或酸化的磷酸氟对复合材料处理后表面的影响，以及复合材料与树脂胶结物之间的界面。与对照不同，氢氟酸或氟化物处理后的所有试件表面都出现微孔表面，但表面处理对所有复合材料结合强度的影响并不相同。粘结剂的使用对复合材料的粘结有一定的影响，但复合材料的增量固化对树脂水泥的粘结没有影响。
