摘　　要：本实验对Ｐｌａｔ铸造陶瓷（ＰＣＣ）和ＳＤＡ－Ⅱ型中熔合金采用不同的表面处理和３种粘接剂粘接，并结合扫描电镜现实及Ｘ线能谱分析，考查其抗张粘接强度（ＴＢＳ），以选出最佳粘接剂及其界面处理方式。结果表明：①ＴＦ粘接剂在本实验中粘接性能最好。②当使用ＴＦ粘接剂，陶瓷表面用氢氟酸处理，合金表面用ＫＨ－５７０涂布时，ＴＢＳ最大，为２４．３７ＭＰａ；当使用ＥＭ粘接剂，陶瓷表面用氢氟酸处理，合金表面喷砂时，ＴＢＳ较大，为１５．２０ＭＰａ；而使用Ｐｏｒｃｅｌｉｔｅｄｕａｌｃｕｒｅｃｅｍｅｎｔ粘接剂，陶瓷表面涂布ＫＨ－５７０，合金表面喷砂时，ＴＢＳ较大，为１５．２５ＭＰａ。Plat castable ceramics(PCC)was bon-ded to SDA-Ⅱ mild fusing alloy using three bondingagents,and the tensile bond strengths were tested re-spectively in order to select the best bonding agent andthe best way of surface treatment. The results ob-tained with scanning electron microscope and X-rayenergy spectrum showed that the bonding behavior ofTF agent was the best one. The greatest tensille bondstrength(24.37 MPa)was obtained with TF agentwhen the surface of PCC was etched by hydrofoluoricacid and the alloy was painted with KH-570.Remark-able tensile bond strengths were noted in the groupwhere EM agent was used with PCC etched by hy-drofluoric acid and alloy treated with sandblasting(15. 20 MPa),and in the group where porcelite dualcure cement was applied with PCC painted by KH-570and alloy treated with sandblasting (15. 25 MPa).
