Embodiment Construction

[0028] Please check figure 1 , the preparation method of the base material with copper-based dispersed bimetallic self-lubricating material, it comprises the steps:

[0029] Step 1, a mixing step, is used to put the copper-based alloy powder and the solid lubricant powder into a V-shaped mixer and mix for 1 to 5 hours;

[0030] Step 2, a powder spreading step, is used to spread the mixed powder evenly on the metal plate; the metal plate is a steel plate pretreated by copper plating;

[0031] Step 3, the loose-pack sintering step, is used to heat and sinter the powder-coated metal plate in a protective atmosphere, the sintering temperature is 750-860°C, and the sintering time is 0.5-2 hours;

[0032] Step 4, a rolling step, for rolling the metal plate in step 3 into a semi-finished product;

[0033] Step 5, the re-sintering step is used to heat and sinter the semi-finished product in a protective atmosphere, the sintering temperature is 750-860°C, and the sintering time is 0....

Abstract

The invention discloses a copper-based dispersive bimetallic self-lubricating material and a method for preparing a self-lubricating base material. The method for preparing the base material comprises the following steps of: 1, mixing, namely mixing copper-based alloy powder and solid lubricant powder, wherein the solid lubricant powder comprises molybdenum disulfide and graphite, and the weight ratio of the copper-based alloy powder to the molybdenum disulfide to the graphite is (87-96):(0.5-3):(3-8); 2, spreading the powder, namely uniformly spreading the mixed powder on a metal plate; 3, loosely packing and sintering, namely heating and sintering the metal plate with spread powder at the temperature of between 650 and 1,000 DEG C under protective atmosphere; 4, rolling, namely rolling the metal plate in the step 3 into a semi-finished product; and 5, resintering, namely heating and sintering the semi-finished product at the temperature of between 650 and 1,000 DEG C under the protective atmosphere.

Description

technical field [0001] The invention relates to a copper-based dispersed bimetallic self-lubricating material and a method for preparing a self-lubricating base material, in particular to a material with good friction and wear properties produced by using metal powder and non-metal powder. Background technique [0002] Bimetallic materials are widely used in my country's industrial manufacturing. It can save non-ferrous metals and is widely used in various fields such as automobiles, aircraft manufacturing, and engineering machinery. Dispersed bimetallic self-lubricating materials are a new type of bimetallic materials. The material contains a variety of solid lubricants. Compared with the original ordinary bimetallic materials, it has the characteristics of low friction coefficient, high wear resistance, strong bearing capacity and good high-temperature self-lubricating performance (<300°C). [0003] China Patent Database announced on October 25, 2006 a utility model tit...
