【摘要】 通过在ＺｒＯ２与４０Ｃｒ钢的钎焊连接中加入缓冲层４Ｊ３３，Ｎｉ，Ｔｉ和Ｃｕ，来研究缓冲层化学成分对连接强度的影响。结果表明，４Ｊ３３和Ｎｉ因其化学元素与钎料发生化学反应，损害了钎料的活性，致使ＺｒＯ２／缓冲层／４０Ｃｒ钢连接失败；而缓冲层Ｔｉ和Ｃｕ虽然大量溶入钎料中，但并不影响钎料和ＺｒＯ２的反应结合，故可提高ＺｒＯ２／４０Ｃｒ钢的连接强度。更多还原

【Abstract】 In this paper,we make a research on the effect of chemical composition of buffer on joint strength by inserting 4J33,Ni,Ti and Cu between ZrO 2 and steel 40Cr.The results indicate:the chemical reaction between 4J33,Ni and brazing alloy harms the activity of solder and damages the bonding of ZrO 2/buffer/40Cr;although Ti and Cu dissolive into the brazing alloy greatly,they don′t affect the reaction between ZrO 2 and solder and improve the jiont strength of ZrO 2/40Cr.更多还原
