Problems solved by technology

However, studies have shown that when TiB 2 When the cermet is deposited on the surface of the copper alloy electrode by EDM, part of the copper is melted and mixed into the coating, because copper is not a good binder for the cermet, thus reducing the toughness of the cermet
On th...

Embodiment Construction

[0032]In the resistance welding copper alloy electrode provided by the present invention, three layers of materials are first distributed on the substrate 1 at the end of the electrode, the metal alloy layer 2 is in contact with the substrate, the metal alloy composite material layer 3 is in the middle, and the outermost surface is a metal alloy layer 4. The thickness of the metal alloy layer in contact with the substrate is 10-40 microns, and the thickness of the metal alloy composite material layer in the middle is 20-50 microns. In order to better prevent the adhesion of electrodes, a layer of dense metal alloy layer formed by chemical vapor deposition method or physical vapor deposition method or high-speed cold gas flow spraying WS2 method is used outside the metal alloy layer on the outermost surface. The thickness is about 0.5 microns.

[0033] The composition of the above-mentioned first three layers of materials: the metal alloy layer in contact with the substrate an...

Abstract

The present invention relates to a resistance welding copper alloy electrode and its production method. It is characterized by that in said electrode, on the matrix of electrode end portion at least three layers of materials are distributed, they are metal alloy layer contacted with said matrix, intermediate metal alloy composite material layer and external surface metal alloy layer. Besides, said invention also provides the concrete steps of its production method. Said copper alloy electrode has high working reliability and long working life.

Description

(1) Technical field [0001] The invention relates to a resistance welding copper alloy electrode and a manufacturing method thereof. (2) Background technology [0002] Due to the excellent corrosion resistance of galvanized and galvanized aluminum sheets (including electroplating, hot-dip and evaporation plating), they have been more and more widely used in the fields of automobiles, home appliances, and construction in recent years. Especially in the automotive industry, galvanized sheets have been widely used to produce parts such as car bodies and welded by resistance welding. However, during resistance welding of galvanized steel sheets, the service life of resistance welding electrodes (including electrode heads, electrode caps, electrode plates and electrode wheels) is significantly shorter than that of uncoated steel sheets. When welding uncoated steel plates, the service life of resistance welding electrodes (such as Cu-Cr-Zr alloy electrodes) is usually more than 10...
