Description
Technical field
The present invention relates to the alloy plating liquid in a kind of material surface process field, specifically a kind of cobalt-tungsten-iron nickel alloy electroplate liquid.
Background technology
At present, the eccentric wear and the corrosion phenomenon in petroleum machinery field are serious, also there is not a kind of process for treating surface of satisfaction can be used for the surface treatment of petroleum machinery, can possess anticorrosion antiwear and with low cost simultaneously, continuous consumption along with petroleum resources, the environment of recover petroleum is more and more abominable, and is more and more higher to the corrosion-resistant crocking resistance requirement of oil equipment.Therefore, the anticorrosion antiwear technology of research petroleum machinery is the problem that people are absorbed in always.
A kind of scheme that may solve is a tungsten alloy plating, tungsten can not be independent come out from aqueous solution electrodeposition, but can and iron family element ting (iron, nickel, cobalt) together induced codeposition come out, obtain the tungstenalloy of various components, the ferrotungsten of picture known technology, nickel tungsten, ferrum-nickel-tungsten alloy etc. can obtain non-crystaline amorphous metal through control.But above plating exists fragility big (ferrotungsten), electrodeposition rate slow (ferrum-nickel-tungsten alloy), apparent shortcoming such as tiny crack is arranged, and has limited its range of application.
