Abstract
The invention relates to silver-and copper-based composite contact materials which are made by compounding a copper substrate layer and a silver-based layer. Adjacent interfaces of the silver-based layer and the copper substrate layer form a bonding zone through metallurgical bonding. The bonding zone is made of copper substrate materials and silver-based materials. The thickness of the silver-based layer is 0.01-2mm. Adjacent interfaces of the silver-based layer and the copper substrate layer form a bonding zone through metallurgical bonding. The bonding zone is made of the copper substrate materials and the silver-based materials, that is, a certain level of metallurgical bonding between the silver-based materials and the copper substrate materials is reached. A working layer of a contact is greatly deepened, and thereby enabling the silver- and copper-based composite contact materials to be applicable to electrical equipment which needs large electric current when working, such as switches, relays and contactors.
Description
Technical field
The present invention relates to a kind of silver/copper base composite contact material.
Background technology
Contact material is generally by add a certain amount of refractory metal or oxide in simple metal, to improve its breaking capacity and arc resistant scaling loss ability.The disclosed a kind of silver/copper of Chinese patent 93115832.X/Ag/Cu/Ag-Cu-Zn contactor composite, the silver-based material that is used for raising contact breaking capacity and arc resistant burning ability is combined by cold rolling compound mode with the copper basis material, although saved to a certain extent silver-colored consumption, but because the metallic atom of bi-material is low in conjunction with rate, so that the contact working lining is only at silver/silver-based material layer, base material can not continue to use, the silver of this structure/copper base composite contact material only can be applicable to the little device for switching of loading, and effect is undesirable.
Summary of the invention
The object of the invention is to overcome the defective of prior art, provide a kind of silver/silver-based material atom in copper basis material atom, to spread, reach metallurgical binding, be applicable to the silver of high current load work/copper base composite contact material.
For achieving the above object, the present invention adopts a kind of like this silver/copper base composite contact material, by the copper base layer with silver-based layer is two-layer is composited, the mutual metallurgical binding of the adjacent interfaces of described silver-based layer and described copper base layer forms calmodulin binding domain CaM, described calmodulin binding domain CaM is made of copper basis material and silver-based material, and the thickness of described silver-based layer is 0.01～2 millimeter.
