Wherein, described intensified element is selected from one or more combination of tin, phosphorus, nickel;
10～15% of copper total amount is 400 order powder; Iron and surplus copper are 100 order powder;
Prepare in the following order:
Mixed powder-shaping-low temperature presintering-high temperature sintering-surface finish-antirust processing-finishing-cleaning-vacuumImmersion oil;
The temperature of low temperature presintering is 400 DEG C.
Further, described intensified element is tin and phosphorus, and wherein, tin consumption is 1-3 part, and phosphorus consumption is greater than 0 and is less than 1 part.
The present invention also provides the preparation method of above-mentioned high abrasion bearing, and it is to prepare in the following order: mixedPowder-shaping-low temperature presintering-high temperature sintering-surface finish-antirust processing-finishing-cleaning-vacuum oil immersion.
Further, the temperature of low temperature presintering is 400 DEG C.
The present invention uses specific raw material proportioning and special raw material to add mode, ensureing on the basis of lower cost,Effectively improve the anti-wear performance of bearing, there is more good prospects for commercial application.
