节约贵金属的必要性、比单金属或电镀制品更高的使用性能是银、金、铂、钯双金属工业消耗不断增长的主要原因。通过叠轧、挤压、模锻、扩散焊接、爆炸焊接等各种固相粘结方法达到了焊接金属层的高质量、包复表面部分的可能性、不仅用纯金属还用合金包复的可能性、在包复层中没有疏松和不连续性、尺寸的宽广范围和高生产率。实行固相粘结和进一步加工实际上可以获得贵金属及其合金与有色金属、合金和钢的任何组合。我们研究了一些典型的双金属及其有关的生产和应用问题。
The need to save precious metals, higher performance than single metal or plated products is the main reason for the growing consumption of silver, gold, platinum, palladium bimetal industry. Through the rolling, extrusion, die forging, diffusion welding, explosion welding and other solid-phase bonding method to achieve the high quality of the welded metal layer, the possibility of cladding the surface portion, not only with pure metal alloy coated Possibility of no laxity and discontinuity in the cladding, wide range of dimensions and high productivity. Practicing solid-phase bonding and further processing can indeed achieve any combination of precious metals and their alloys with non-ferrous metals, alloys and steels. We studied some typical bimetallic and related production and application issues.
