    • PROBLEM TO BE SOLVED: To provide a method for producing a welding material capable of overcoming all of six problems including a problem that cracking of an extrusion-molded product often occurs during a defatting step or a sintering step and a problem that the extrusion-molded product is disrupted readily.SOLUTION: The method for producing the welding material comprises, in the following order: a compound production step S2 of kneading alloy powder containing first alloy powder having a first average particle diameter and second alloy powder having a second average particle diameter, a water-soluble binder and water to produce a compound; a drying step S4; an extrusion step S6; a defatting step S8 of heating the extrusion-molded product to a predetermined temperature equal to or higher than 400°C; a C-O reaction step S10 of heating the extrusion-molded product to a predetermined temperature that ranges from 950°C-1150°C in a vacuum atmosphere; and a sintering step S12 of heating the extrusion-molded product to a predetermined temperature that ranges from 1200°C-1350°C in a nitrogen gas atmosphere to produce the welding material.
    • 要解决的问题:提供一种能够克服所有六个问题的焊接材料的制造方法,包括在脱脂步骤或烧结步骤中经常发生挤出成型制品的开裂的问题,以及 挤出成型产品容易破裂。 解决方案:焊接材料的制造方法按照以下顺序包括:将含有第一平均粒径的第一合金粉末和第二平均粒径的第二合金粉末混合的合金粉末的复合制造工序S2, 水溶性粘合剂和水,以产生化合物; 干燥步骤S4; 挤出步骤S6; 将挤出成型品加热到400℃以上的规定温度的脱脂工序S8; 在真空气氛中将挤压成型品加热至规定温度为950℃〜1150℃的C-O反应工序S10; 以及在氮气气氛中将挤压成型体加热至规定温度为1200℃〜1350℃的烧结工序S12,制作焊接材料。 版权所有(C)2012,JPO&INPIT
