Problems solved by technology

In order to reduce the loss caused by wear, on the one hand, the anti-wear and anti-friction properties of various lubricating materials are continuously improved, and the lubrication state of mechanical parts is improved. However, the processing technology of high-grade synthetic lubricating materials is complicated and the cost is high, and it is still unable to solve the problem of metal parts. The problem of severe wear and tear under harsh c

Embodiment

[0029] Micronized Serpentine Mineral: 45%,

[0030] Micronite mineral powder: 10%

[0031] Lanthanum Rare Earth Fluoride: 5%

[0032] Iron oxide: 3%

[0033] Aluminum Oxide: 2%

[0034] Sorbitan Monopalmitate: 35%

[0035] Put the raw materials in the above ratio into a high-speed mixer and stir for 1 hour, and then grind them in a high-speed ball mill for 4 hours to obtain a powder with a particle size of less than 1 micron.

[0036] Then mix 0.2% of the above powder material with 99.8% of industrial lubricating oil, and stir at 70° C. for 2 hours to obtain a lubricating oil that uniformly mixes the wear surface of the metal part with online strengthening and repairing materials.

[0037] The end face friction and wear test was carried out with the lubricating oil of the online strengthening and repairing material on the worn surface of the above-mentioned mixed metal parts as a sample, and the friction pair material was 45 # steel. The test results show that the fricti...

Abstract

The invention relates to an on-line strengthening repair material for the worn surfaces of metal parts, as well as a preparation method thereof. The components in percentage by weight of the repair material consist of 30 to 60 percent of serpentine mineral micro-powder, 5 to 10 percent of ulexite mineral micro-powder, 5 to 10 percent of lanthanum fluoride rare earth, 2 to 5 percent of iron oxide micro-powder, 2 to 5 percent of alumina micro-powder and 40 to 50 percent of sorbitan mono-palmitate. The preparation method comprises the following steps that: the well proportioned raw materials are put into a high-speed stirrer to be stirred for one hour, and then is ground for four hours by a high-speed ball mill so as to acquire powder with the particle size less than one micron, thus the on-line strengthening repair material for the worn surfaces of metal parts is formed. The invention also discloses a method for using the material. The on-line strengthening repair material for the worn surface of metal parts can form high-hardness surface modified strengthening repair layers on the worn surfaces of metal parts, realize the non-disassembly maintenance of machinery, remarkably improve the wear resistance of parts and prolong the life span of equipment.

Description

technical field [0001] The invention relates to an on-line strengthening and repairing material for the wear surface of a metal part and a preparation method thereof, in particular to an on-line strengthening and repairing material which can repair the wear surface of a metal part without disintegration and can significantly improve the surface hardness and wear resistance of the part and its preparation method. The preparation method also relates to the application method of the material. Background technique [0002] Wear is one of the three main forms of failure of mechanical materials, and the economic losses caused by wear and tear of mechanical equipment in my country are as high as hundreds of billions of yuan every year. In order to reduce the loss caused by wear, on the one hand, the anti-wear and anti-friction properties of various lubricating materials are continuously improved, and the lubrication state of mechanical parts is improved. However, the processing tec...
