| 摘 要： | 研究制备了以有机金属盐甲基磺酸亚锡为主要活性成分的新型304不锈钢软钎焊用H36钎剂,并配合Sn-Cu-Ni钎料比较了其与传统H3PO4-C2H5OH钎剂、ZnCl2-HCl钎剂和ZnCl2-NH4Cl钎剂在304不锈钢基板上的润湿铺展性能.结果表明,新研制的H36钎剂的铺展性能明显优于其它钎剂,其最大铺展面积达到109.56 mm2,相比H3PO4-C2H5OH钎剂和ZnCl2-NH4Cl钎剂分别提高了249.4％和239.3％;添加乳化剂6500能进一步提高钎剂的润湿铺展性能,最大铺展面积可达到157.49 mm2.对优化后的H36-2钎剂匹配Sn-Cu-Ni钎料钎焊304不锈钢钎焊接头力学性能的结果表明,钎焊接头的抗拉和抗剪强度分别达到22.72 MPa和33.93 MPa,优于现有文献报道的数据.

| Abstract: | The spreading properties of Sn-Cu-Ni solder on 304 stainless steel sheet were studied by matching different fluxes, and the results indicated that Sn-Cu-Ni solder has excellent spreadability when it is matched with newly developed flux of H36. Its spreading area reaches 109.56 mm2,which is increased by 249.4%,239.3% compared with fluxes of H3PO4-C2H5OH and ZnCl2-NH4Cl,respectively. Results also indicated that the emulsifier 6500 can further improve the spreadability, and the largest spreading area reaches 157.49 mm2. It was found that,when the optimized flux H36-2 is matched with Sn-Cu-Ni as solder for 304 stainless steels,the mechanical properties of the soldered joints are superior to the existing literature data,the tensile strength and shear strength of the joints reached up to 22.72 MPa and 33.93 MPa,respectively. |
