Abstract
The invention relates to alloy powder, which belongs to metallurgy industry and is used for improving hardness of the metal surface material, improving corrosion resistance and wear resistance and prolonging service life of equipment. The invention particularly relates to copper nickel molybdenum cobalt alloy self-fusing powder. The invention is characterized in that: the copper nickel molybdenum cobalt alloy self-fusing powder is synthesized by the following raw materials in percentage by weight: 15 percent of copper, 45 percent of nickel, 20 percent of molybdenum and 20 percent of cobalt; and the copper, the nickel, the molybdenum and 17 volume percent of cobalt, which are mixed, are mixed with 83 volume percent of iron powder. The wear resistance of the copper nickel molybdenum cobalt alloy self-fusing powder is increased by 20 to 40 times compared with that of the original metal materials. After extrusion, the hardness is higher and higher and finally reaches 65 Rockwell hardness (HRC).
Description
Technical field
The invention belongs to hardness, the raising corrosion-resistant and wear resistance of metallurgy industry in order to improve the metallic surface material, the powdered alloy that prolongation equipment uses is particularly about copper nickel molybdenum cobalt-base 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 mill roll more or less a hundred, so it is very big to keep in repair market.Increasing utilizes our powdered alloy cladding and technique for overlaying; Repair in the course of processing in the weld deposit process with roll at column and to use powdered alloy that copper, nickel, molybdenum, cobalt dust are arranged, copper, nickel, molybdenum, cobalt dust fly upward the content that has reduced copper, nickel, molybdenum, 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 copper nickel molybdenum cobalt-base alloy self-fluxing nature powder, it can overcome above deficiency, improves hardness, corrosion and the wear resistance of metallic surface material, prolongs the work-ing life of equipment.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is: a kind of copper nickel molybdenum cobalt-base alloy self-fluxing nature powder is provided, it is characterized in that: it is synthetic by following raw materials by weight percent; Copper 15%, nickel 45%, molybdenum 20%, cobalt 20%; By volume per-cent will be handled mixed copper, nickel, molybdenum, cobalt 17% and the processing of 83% iron powder mix again.
Above-mentioned copper nickel molybdenum cobalt-base alloy self-fluxing nature powder blending process process is:
1) gets copper 15%; Nickel 45%; Molybdenum 20%; Cobalt 20%, part by weight configure each raw material powder;
2) with copper, nickel, molybdenum, the cobalt dust of aforementioned proportion, be under-0.08 condition in vacuum tightness 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 tightness;
4) copper after the above-mentioned processing, nickel, molybdenum, cobalt dust are mixed according to the above ratio, mixed volume accounts for 17% preparation of whole volume;
5) get 3) account for total volume percent 83% iron powder after handling;
6) then with 5) 83% iron powder and 4) 17% copper, nickel, molybdenum, the cobalt dust that account for whole volume after mixing put in the three-dimensional rotation 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 copper nickel molybdenum cobalt-base alloy self-fluxing nature powder behind the taking-up ball milling is under-0.08 condition in vacuum tightness, 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 copper nickel of the present invention molybdenum cobalt-base 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 index compare:
Hardness: original metal material surface hardness is 40～45HRC;
The present invention is＞42HRC through copper nickel molybdenum cobalt-base alloy metal material surface initial stage hardness;
Wear resistance: improve 20～40 times than original metallic substance wear resistance.
Can reach 65HRC through the increasingly high final hardness of compression stiffness.
