【摘要】 介绍了触头材料静熔焊实验结果，分析了材料表面的成分变化规律和形貌状态，指出在静熔焊条件下，接触熔化区中的低熔点金属含量与其原始含量相比明显增多，而高熔点金属含量减少。对于含Ｗ很高的ＡｇＷ材料，其熔区表面呈颗粒状，而ＡｇＣｕ熔区呈水纹状。探明了熔化变形面积与接触加热能量及材料性质参数有关且其变形大小与静熔焊概率大小一致。更多还原

【Abstract】 The experimental results of the static fusion welding of contact materials are reportedand the changes of surface composition and distribution as well as the morphology are ana-lyzed. It is pointed out that the percentage content of metals with a lower melting point is in- creased compared with the original one, but that of metals with a higher melting point goesthe other way round.The morphology on the welding zone is of particle state for AgCu ma-terial. The melting deformation area is dependent on the energy heating the contact surface,the meterial parameters and the deformation is identical with the welding probability.更多还原
