Problems solved by technology

The copper-based alloy of the traditional copper-based-steel bimetal bearing material is composed of copper, lead, tin, zinc (or phosphorus). Because it contains lead, it is poisonous to the human body and pollutes the environment, so it has been gradually reduced in use recently.

Embodiment Construction

[0008] Such as figure 1 Shown is the schematic diagram of the present invention, which is composed of a steel plate 1 and a copper-based alloy wear-resistant layer 2; wherein, the formula composition of the copper-based alloy wear-resistant layer 2 is by weight percentage: bismuth 1% to 15%, tin 0.5% % to 10%, zinc 0.3% to 15%, and the balance copper.

[0009] A layer of copper 11 is plated on the steel plate 1 in the present invention.

[0010] In specific implementation, copper plating 11 or no copper plating 11 can be performed as required.

[0011] In the present invention, the copper-based alloy wear-resistant layer 2 is sintered or cast on the steel plate 1 .

[0012] The sintering in the present invention refers to the composition of the copper-based alloy wear-resistant layer 2, pre-prepared by 1% to 15% of bismuth, 0.5% to 10% of tin, 0.3% to 15% of zinc, and the balance is copper. The mixture is melted and atomized into copper-based alloy powder, and then the copp...

Abstract

The invention relates to manufacture of a metal plate, in particular to an environment-friendly copper base-steel bimetal shaft bushing material and a manufacturing method thereof. The invention adopts a technical proposal that the material consists of a steel plate and a copper base alloy abrasion-resistant layer, wherein the copper base alloy abrasion-resistant layer comprises the following components in percentage by weight: 1 to 15 percent of bismuth, 0.5 to 10 percent of tin, 0.3 to 15 percent of zinc, and the balance being copper; and the copper base alloy abrasion-resistant layer is directly sintered or poured on the steel plate. The material and the method have the advantages that because the bismuth is used for replacing lead in the copper base alloy, the material does not contain the lead, has no harm to human body or pollution to environment, and is the environment-friendly copper base-steel bimetal shaft bushing material.

Description

technical field [0001] The invention relates to the manufacture of metal plates, in particular to an environment-friendly copper-steel bimetallic bearing bush material and a manufacturing method thereof. technical background [0002] The copper-based-steel bimetallic bearing material is made by sintering or casting a layer of copper-based alloy on the surface of copper-plated (mainly to prevent rust) or non-copper-plated steel plate. It is widely used in various automobile engines and diesel engines. The basic material of various bearing pads, flanged bearing pads, bearings, bushings, and bushings used. The copper base alloy of the traditional copper base-steel bimetallic bearing material is composed of copper, lead, tin, zinc (or phosphorus). Because it contains lead, it is poisonous to the human body and pollutes the environment, so it has been gradually reduced in use recently. The European Union's "Restrictions on the Use of Certain Hazardous Substances in Electrical an...
