温度对陶瓷/铁基金属结合剂性能与结构的影响
|
摘要
采用粉末冶金法制备低温陶瓷/铁基金属结合剂。结合材料电子万能试验机、SEM、XRD等检测手段,研究了烧结温度对低温陶瓷/铁基金属结合剂性能与结构的影响。结果表明:当热压烧结温度为740℃时,低温陶瓷/铁基金属结合剂具有最佳的力学性能(抗折强度206 MPa,冲击强度6.4 kJ/m~2);温度升高促进了低温陶瓷与铁基结合剂界面之间元素的相互渗透,铁基金属结合剂与低温陶瓷达到最佳的机械嵌合,提高结合剂强度。
Low temperature vitrified/Fe-based bond was prepared by powder metallurgy method. The effect of sintering temperature on the properties and structure of low temperature vitrified/Fe-based bond were investigated by means of three-point bending test,SEM and XRD. The results show that when the sintering temperature was 740 ℃,the mechanical property of vitrified/Fe-based bond reach its maximum value 206 MPa and 6. 4 k J/m~2,respectively. The temperature rise promotes the interaction of the elements of the interface between the low temperature ceramic and the iron base bond,and the iron base metal bond and the low temperature vitrified achieves the best mechanical fitting.
