Effect of Silica Coating with Perhydropolysilazane on Resin Bonding to Y-TZP ceramic

研究了过氢聚硅氮烷（PHPS）涂层对氧化锆（Y-TZP）陶瓷与氧化钇稳定氧化锆（Y-TZP）陶瓷结合性能的影响。本实验对两种5% PHPS溶液（NP-110, NL-120）进行了评价，以获得有效的加热方案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℃下加热均可获得较高的结合强度。其中，含pd -催化剂的NL-120包覆二氧化硅（500℃，10m）后VUV辐照（185nm, 10m）的结合强度显著提高。新型PHPS涂层技术是Y-TZP陶瓷与树脂粘接的有效方法。

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.
