Embodiment Construction

[0061] The present invention will be described in further detail below in conjunction with accompanying drawing

[0062] refer to figure 1 , figure 2 , there is a metal transition layer on the surface of the substrate, and there are one or more wear-resistant layers outside the metal transition layer. The wear-resistant layer is a superhard material-metal composite coating, and the superhard material is diamond, boron carbide, boron nitride , corundum, silicon carbide or a combination thereof.

[0063] The electrodeposited metals of the transition layer and wear-resistant layer can be unit, binary or multi-element alloys, such as unit metals such as nickel, iron, manganese, cobalt, tungsten, phosphorus, or binary metals or multi-element metals, such as nickel-iron alloys , Nickel-manganese alloy, nickel-tungsten alloy, nickel-phosphorus alloy, nickel-cobalt alloy, nickel-cobalt-manganese alloy, nickel-tungsten-phosphorus alloy layer.

[0064] The surface treatment method o...

Abstract

The invention provides a surface treatment method for abrasion-proof accessories. The surface treatment method is characterized in that a common metal material serves as a substrate; one metal alloy transition layer is electrically deposited on the part of the substrate, which directly acts on substances, such as mud, gravel, powder, slurry and the like, by using methods of electroplating, electroforming or chemical plating or the like; one or more layers of superhard material-metal composite coating containing superhard material particles as abrasion-proof layers are electrically deposited on the metal alloy transition layer by using methods of electroplating, electroforming or chemical plating or the like; and thus, the part has the service life which is more than 10-20 times that of the existing abrasion-proof accessories. The surface treatment method has the advantages of obvious economic benefit and social benefit.

Description

technical field [0001] The invention relates to the technical field of wear-resistant composite metal materials, and specifically refers to the surface treatment technology of wear-resistant accessories that are in direct contact with working materials during operation. Background technique [0002] At present, in some mechanical fields, such as: brick-making machinery, tile-making machinery, tillage machines, harvesters and other agricultural machinery; bulldozers, excavators, loaders, road pavers and other construction machinery; river dredgers, mud ash Water conservancy engineering machinery such as sand pumps; mining machinery; sandblasting machinery such as foundry sand cleaning and shipbuilding sandblasting; printing and dyeing machinery, textile machinery applications; powder conveying machinery such as metallurgical industry, coal industry, and chemical industry. Mechanical working devices in these industries and fields, which directly act on wear parts such as soil,...
