摘要: 采用化学镀作为先导工艺,使陶瓷表面金属化。然后在辉光炉中进行了陶瓷—陶瓷或陶瓷—金属的无钎剂钎焊。试验表明,选用铜用为镀层材料可有效地改善陶瓷的钎焊性能;只要在足够的镀铜层厚度和合适的工艺参数,可以获得外形美观、无内在缺陷、并具有足够强度的良好接头。对工艺参数的影响、接头微观结构及结合机理进行了探讨。本方法具有广泛的应用前景。

Abstract: The chemical plating is used as a precursory procedure to metallize ceramics surface, and then ceramic to ceramic or to metal is brazed in glow discharge furnace without flux. It is shown by experiments that copper, chosen as the material of the plating layer, can effectively improve the brazability of ceramics. Provided the plating layer thickness is enough and the brazing parameters are suitable, a satisfactory joint, with good looking and sufficient strength and without discontinuity, can be obtained. In addition to the influences of the technological parameters, the joint microstracture and the jointing mechanism are discussed. This process can extensively be used in industry.
