dc.description.abstract碳化锆(ZrC)具有高熔点、高硬度、耐热性、高强度、高弹性磨量，良好的化学稳定性、电导性和热导性等，其晶须可做为WRM（晶须强化金属）、WRC（晶须强化陶瓷）等复合材料的补强材料。目前ZrC晶须的制备研究主要采用化学气相沉积法（CVD），而碳热还原法制备ZrC晶须鲜有报道。本论文采用金属锆有机物和环氧树脂为原料，通过碳热还原法制备得ZrC晶须。在论文第二章，将Zr(acac)4或ZrCl4·2THF、环氧树脂、固化剂按一定比例溶于二氯甲烷中，涂覆于石墨基板，固化制得环氧复合物。在惰性气氛（氩气）下，将此复合物于800℃充分预裂解后，再于1400℃、1500℃和1600℃保温处理90分钟。用XR...
dc.description.abstractZirconium carbide has a high melting point, hardness, chemical stability and is also a good thermal and electrical conductor. Whiskers with such characteristics have a high potential as reinforcing materials for metals and ceramics. Chemical Vapor Deposition (CVD) of zirconium carbide whisker was so far reported by many authors, while there were little reports based on the carbothermal reduction. ...
