Abstract
The invention belongs to the metallurgy industry, and particularly relates to a self-fluxing carbon-boron-nickel-cobalt alloy powder, which is used for increasing hardness of metal surface materials, improving corrosion resistance and wear resistance of the metal surface materials and prolonging the service life of equipment. The self-fluxing carbon-boron-nickel-cobalt alloy powder is characterized by being prepared by steps of mixing the raw materials, by weight percentage, 20% of carbon, 15% of boron, 23% of nickel and 42% of cobalt into carbon-boron-nickel-cobalt powder, and then mixing 26% of the carbon-boron-nickel-cobalt powder with 74% of iron powder according to the volume percentage. With the self-fluxing carbon-boron-nickel-cobalt alloy powder, the wear resistance of carbon-boron-nickel-cobalt alloy powder alloyed metal materials can be increased by 20-40 times as compared with that of the original metal materials, and the hardness is increased higher and higher until the finish hardness reaches 65HRC(Rockwell C hardness) after the metal materials are extruded.
Description
Technical field
The invention belongs to hardness, the raising corrosion-resistant and wearability of metallurgy industry in order to improve the metal surface material, the alloy powder that prolongation equipment uses is particularly about a kind of carbon boron nickel cobalt (alloy) self-fluxing nature powder.
Background technology
Along with national economy is fast-developing, the coal industry also increases with the cement sectors demand day by day, and construction of coal mine is at large-scale development, the colliery with column demand every year all about up to ten thousand, cement plant roll more or less a hundred, so it is very big to keep in repair market.Increasing utilizes our alloy powder cladding and technique for overlaying; Repair in the process in the weld deposit process with roll at column and to use alloy powder that carbon, boron, nickel, cobalt dust are arranged, carbon, boron, nickel, cobalt dust fly upward the content that has reduced carbon, boron, nickel, cobalt and can not make it reach optimum performance in weld deposit process.
Summary of the invention
The purpose of this invention is to provide a kind of carbon boron nickel cobalt (alloy) self-fluxing nature powder, it can overcome above deficiency, improves hardness, corrosion and the wearability of metal surface material, prolongs the service life of equipment.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is: a kind of carbon boron nickel cobalt (alloy) self-fluxing nature powder is provided, it is characterized in that: it handles the synthetic carbon boron nickel cobalt dust in back by carbon 20%, boron 15%, nickel 23%, cobalt 42% raw materials by weight percent; By volume percentage will be handled mixed carbon boron nickel cobalt 26% powder and the processing of 74% iron powder mix again.
Above-mentioned a kind of carbon boron nickel cobalt (alloy) self-fluxing nature powder preparing process process is:
1) gets carbon 20%, boron 15%, nickel 23%, cobalt 42% part by weight and configure each material powder.
2) with carbon, boron, nickel, the cobalt dust of aforementioned proportion, be under-0.08 condition in vacuum respectively, with insulation under 120 ± 5 ℃ the temperature two hours;
3) be under-0.08 condition also with iron Fe powder, with insulation under 120 ± 5 ℃ the temperature two hours in vacuum;
4) carbon after the above-mentioned processing, boron, nickel, cobalt dust are mixed according to the above ratio, mixed volume accounts for 26% preparation of whole volume;
5) get 3) account for total volume percent 74% iron powder after handling;
6) then with 5) 74% iron powder and 4) 26% carbon, boron, nickel, the cobalt dust that account for whole volume after mixing put in the three-dimensional rotation batch mixer and mixed 8-12 hours;
7) with mixed 6) powder puts ball mill into-24 ℃ to-30 ℃ ball millings 8-10 hours;
8) the carbon boron nickel cobalt (alloy) self-fluxing nature powder behind the taking-up ball milling is under-0.08 condition in vacuum, gets final product in two hours with insulation under 120 ± 5 ℃ the temperature.
The present invention compared with prior art, advantage and effect that the present invention has are following:
This carbon boron of the present invention nickel cobalt (alloy) self-fluxing nature powder is that a kind of equipment corrosion that is applied to coal mining and cement sectors, wear-resisting, hardness improve greatly, and also the time of having practiced thrift has been improved production efficiency simultaneously, thereby has improved profit.
Technical parameter and performance indications compare:
