树脂与金属的粘接有各种不同的方法。近来,人们采用高温二氧化硅处理合金表面,使树脂与金属之间产生化学性粘接。本文对几种树脂与几种铸造合金的粘接力进行了对比研究。材料和方法3种铸造合金(T_3、维他良和N_(72))和3种树脂用于实验.合金制备成厚2mm、直径11.7mm的圆形模型,喷砂打磨、超声洁治后干燥。模型分别经过下列3种不同的处理:电解、二氧化硅处理、电解和二氧化硅处理. 改良的Kemper-kilian装置用于模型的粘接,粘接后的模型于5℃和55℃热循环处理1000次.万能实验机用于测量抗张结合力.模型剖开后用扫描电镜观
There are different ways to bond the resin to the metal. Recently, high-temperature silica has been used to treat the surface of the alloy to chemically bond the resin to the metal. In this paper, several kinds of resin and several casting alloy adhesion were compared. MATERIALS AND METHODS Three kinds of casting alloys (T_3, Vitalon and N_ (72)) and three kinds of resins were used in the experiment.The alloy was prepared into a round mold of 2 mm in thickness and 11.7 mm in diameter, sand blasting and drying after ultrasonic cleaning. The model was subjected to the following three different treatments: electrolysis, silica treatment, electrolysis and silica treatment. The modified Kemper-kilian apparatus was used for the adhesion of the model. The bonded model was thermally cycled at 5 ° C and 55 ° C Processing 1000. Universal testing machine used to measure the tensile bond strength after the model was cut open with a scanning electron microscope
