摘要：

為了研究低溫常壓等離子體表面改性對(duì)氧化鋯陶瓷與樹(shù)脂粘接耐久性的影響，本文采用了不同等離子體處理方式對(duì)氧化鋯陶瓷表面進(jìn)行處理，通過(guò)剝離力、接觸角和XPS等表征技術(shù)分析了處理前后氧化鋯陶瓷表面的粗糙度、成分和親水性等變化，研究了氧化鋯陶瓷表面改性后與樹(shù)脂粘接的耐久性及其機(jī)理。結(jié)果表明，低溫常壓等離子體表面處理可明顯提高氧化鋯陶瓷表面的親水性，并促進(jìn)樹(shù)脂和氧化鋯陶瓷的接觸，明顯改善樹(shù)脂粘接性，而不同等離子體處理方式對(duì)表面形貌和化學(xué)組成均有所不同，且處理時(shí)間對(duì)粘接強(qiáng)度的影響較大。本研究結(jié)果可為氧化鋯陶瓷表面處理提供一定的理論和實(shí)驗(yàn)方面的指導(dǎo)。
