客观的。本研究的目的是评估硫酮基金属底漆剂对 Ag-Pd-Cu-Au 合金和与丙烯酸树脂粘合的金属部件的粘合行为的影响。材料和方法。圆盘样品（直径 10 毫米，厚 3 毫米）由银-钯-铜-金 (Ag-Pd-Cu-Au) 合金 (Castwell M. C. 12)、高纯银、钯、铜和金制成。对四种含有有机硫化合物的单液体底漆（Alloy Primer、Metaltite、M. L. Primer 和 V-Primer）和三种酸性底漆（All Bond II Primer B、Estenia Opaque Primer 和 Super-Bond Liquid）进行了评估。将金属样品用砂纸磨平，涂上其中一种试剂底漆，并用三正丁基硼烷引发的树脂粘合。在重复热循环（5℃和55℃，各1分钟，20,000个循环）之前和之后测定剪切粘合强度。使用非参数程序对结果进行统计分析（p = 0.05 水平）。结果。对于 Ag-Pd-Cu-Au 合金，与 Alloy Primer、Metaltite、M. L. Primer 和 V-Primer 材料相关的热循环后粘合强度（中值；n = 11）分别为 20.8、22.8、17.8 和 18.4；银为 19.6、21.9、14.4 和 20.1；钯 5.4、4.5、12.8 和 5.3；铜 17.1、19.2、0.7 和 6.6；黄金为 18.5、17.7、22.8 和 15.4。结论。可以得出结论，使用基于有机硫化合物的四种底漆剂有效地增强了Ag-Pd-Cu-Au合金和成分金属的结合，尽管底漆剂和金属元素之间的结合性能有所不同。底漆剂似乎对合金、银和金的影响比对钯和铜的影响更大。
Objective. The purpose of the current study was to evaluate the effect of thione-based metal priming agents on the adhesive behavior of a Ag-Pd-Cu-Au alloy and component metals bonded with an acrylic resin. Materials and methods. Disk specimens (10 mm in diameter by 3 mm thick) were prepared from a silver-palladium-copper-gold (Ag-Pd-Cu-Au) alloy (Castwell M. C. 12), high-purity silver, palladium, copper and gold. Four single-liquid priming agents containing organic sulfur compound (Alloy Primer, Metaltite, M. L. Primer and V-Primer) and three acidic priming agents (All Bond II Primer B, Estenia Opaque Primer and Super-Bond Liquid) were assessed. The metal specimens were flat-ground with abrasive papers, primed with one of the agents and bonded with a tri-n-butylborane initiated resin. The shear bond strengths were determined both before and after repeated thermocycling (5 degrees C and 55 degrees C, 1 min each, 20,000 cycles). The results were statistically analyzed with a non-parametric procedure (p = 0.05 level). Results. The post-thermocycling bond strengths in MPa (median; n = 11) associated with the Alloy Primer, Metaltite, M. L. Primer and V-Primer materials were, respectively, 20.8, 22.8, 17.8 and 18.4 for the Ag-Pd-Cu-Au alloy; 19.6, 21.9, 14.4 and 20.1 for silver; 5.4, 4.5, 12.8 and 5.3 for palladium; 17.1, 19.2, 0.7 and 6.6 for copper; and 18.5, 17.7, 22.8 and 15.4 for gold. Conclusions. It can be concluded that the use of the four priming agents, which are based on organic sulfur compounds, effectively enhanced bonding to the Ag-Pd-Cu-Au alloy and the component metals, although the bonding performance varied among the priming agents and metal elements. The priming agents appeared to have more of an effect on the alloy, silver and gold than on the palladium and copper.
