The aim of this investigation was to evaluate the effect of silica coating with Perhydropolysilazane (PHPS) on the resin bonding to yttria-stabilized zirconia (Y-TZP) ceramic. Two 5% PHPS solutions (NP-110, NL-120) were evaluated in this experiment in order to obtain an effective heating program and, optimum conditionings to heated silica. Relatively high bond strengths were achieved by heating at 500℃ regardless of PHPS solution or heating time. Especially, significantly higher bond strength was obtained for silica-coated with NL-120 (500℃, 10m) containing Pd-catalyst followed by VUV irradiation (185nm, 10m). New PHPS coating technology is an effective adhesive method for bonding resin to Y-TZP ceramic.

本研究的目的是评估二氧化硅涂层与全氢聚硅氮烷（PHPS）的树脂结合到氧化钇稳定的氧化锆（Y-TZP）陶瓷的效果。本实验对两种5%PHPS溶液（NP-110、NL-120）进行了评价，以获得有效的加热程序和加热二氧化硅的最佳条件。无论PHPS溶液或加热时间如何，在500℃下加热都能获得相对较高的粘结强度。特别是用NL-120（500℃，10 m）含Pd催化剂包覆二氧化硅，然后用真空紫外光照射（185 nm，10 m），可获得更高的结合强度。新型PHPS涂层技术是粘结树脂与Y-TZP陶瓷的有效粘结方法。
