【摘要】：用高溫滲碳方法制備氧化鋯陶瓷,研究了滲碳溫度和時(shí)間對(duì)表面電阻率和維氏硬度的影響。結(jié)果表明,高溫滲碳后在氧化鋯陶瓷表面形成了改性層;隨著滲碳溫度的提高和滲碳時(shí)間的延長(zhǎng)表面電阻率下降,維氏硬度升高。滲碳溫度為1450℃、滲碳時(shí)間為3 h的氧化鋯陶瓷,其表面電阻率由1014W/□低至107W/□,維氏硬度略有升高達(dá)到14 GPa。顯微結(jié)構(gòu)和組成分析結(jié)果表明,在氧化鋯陶瓷表面形成了約3μm的改性層。結(jié)果證實(shí),C元素的濃度從表面到內(nèi)部逐漸降低,在內(nèi)部主要以單質(zhì)形式存在,在表層主要以單質(zhì)C及Zr C0.85形式存在,使其具有防靜電性能。
[Abstract]:Zirconia ceramics were prepared by high temperature Carburizing. The effects of Carburizing temperature and time on surface resistivity and Vickers hardness were studied.The results show that the modified layer is formed on the surface of zirconia ceramics after high temperature carburization, and the Vickers hardness increases with the increase of carburizing temperature and the decrease of surface resistivity of Carburizing time.The surface resistivity of zirconia ceramics with Carburizing temperature of 1450 鈩，
