摘要

利用火焰喷涂法制备了聚酰胺1010 (PA1010)/纳米氧化锆（nano-ZrO2）复合涂层。采用示差扫描量热法（DSC）研究其非等温结晶行为，对所得的数据分别用Jeziorny法、Ozawa法和Mo法进行处理。结果表明，用Jeziorny法和Mo法处理非等温结晶过程比较理想，而Ozawa法不适用。用Jeziorny法求出的参数Zc(结晶速率常数）和n（Avrami指数)均随降温速率的增加而增加;nano-ZrO2的加入使复合涂层的Zc和n略大于纯PA1010涂层;并使复合涂层结晶半衰期降低、结晶速率及结晶度增大。表明nano-ZrO2具有明显的成核剂作用，加快PA1010的结晶速率，提高涂层的结晶度。

Abstract

The non-isothermal crystallization kinetics of pure polyamide 1010 (PA1010) coating and PA1010/nano-ZrO2 composite coating prepared by flame spraying

was investigated by differential scanning calorimetry (DSC) at various cooling rates.The Avrami analysis modified by Jeziorny and a new Mo method could describe the non-isothermal crystallization processes of PA1010 and PA1010/nano-ZrO2 composite coating very well.The values of Zc and n increased with increasing cooling rate.The value of kinetic parameter F(T) increased

and the values of a had no significant change with increasing degree of crystallinity for PA1010 and PA1010/nano-ZrO2 composite coating

respectively.The difference in the value of exponent n between PA1010 and PA1010/nano-ZrO2 composite coating suggested that the nano-ZrO2 act as nucleation agents of PA1010.The values of half-time of crystallization and crystallization rate coefficient (CRC) showed that the crystallization rate of PA1010/nano-ZrO2 composite coating was faster than that of PA1010 at a given cooling rate.
