Bonding between porcelain and dental ceramic alloys is thought to be dependent upon the establishment of a continuous electron structure across the ceramic-metal interface (Pask, Proc. Porcelain Enamel Inst.,33,1,1971). Such a structure most likely results from the compatibility of metal ions at the metal surface saturated in an oxide form with the complex oxide structure of the ceramic matrix. Reaction zone compounds are expected to play a prominent role in the strength of the ceramic-metal bonds but thus far none have been detected or identified. The present study was centered on the determination of possible adherence zone compounds in four composite ceramic-metal couples examined by x-ray energy analysis. Elemental analysis of four couples revealed the presence of a predominant Al-Cr interaction resulting from the formation of an Al-Cr-O compound or mixed complex. The Cr ions were supplied by the Cr2O3 oxide layer at the metal surface and the Al was provided by the initial bonding-agent coating.
人们认为，瓷与牙科陶瓷合金之间的结合取决于在陶瓷 - 金属界面上建立连续的电子结构（帕斯克，《搪瓷学会会刊》，第33卷，第1期，1971年）。这种结构很可能是由以氧化物形式饱和的金属表面的金属离子与陶瓷基体的复合氧化物结构的相容性产生的。反应区化合物预计在陶瓷 - 金属键的强度中起重要作用，但迄今为止尚未检测到或鉴定出任何反应区化合物。本研究集中于通过X射线能量分析确定四种复合陶瓷 - 金属偶合物中可能的粘附区化合物。对四对偶合物的元素分析表明，由于形成了Al - Cr - O化合物或混合络合物，存在主要的Al - Cr相互作用。Cr离子由金属表面的Cr2O3氧化层提供，而Al由初始粘合剂涂层提供。
