Step 5:It cools to room temperature with the furnace, the alloy powder block of different size series is pressed into the mold of different model.
Further, the Arabic gum concentration of aqueous solution is 2-5%, the aqueous solution of Arabic gum in every 100g mixed-powders Addition is 10-25ml.
Further, alloy powder block vacuum packing machine encapsulates spare, is used in use, taking out alloy powder block after sealing off TIG Welding Machine built-up welding.
The beneficial effects of the invention are as follows the bond strengths of the WC-VC particles that generation is reacted under the conditions of electric arc reaction and matrix more Height, distribution of particles is more uniform, case hardness higher, and clad surface is high-quality;And it is flexible and convenient to use.
Specific implementation mode
The present invention is described in detail With reference to embodiment.
Using the alloy powder block suppressed after premix as carrier, being prepared using argon tungsten-arc welding fabricated in situ has WC-VC particles The abrasion resistant coating of enhancing.Primary raw material is ferrotungsten powder, pureed graphite, vanadium iron powder and a small amount of ferrosilicon, is added after being pre-mixed uniformly Enter Arabic gum aqueous solution to be stirred for, certain thickness cuboid alloy powder block is pressed into after drying.
Each composition composition quality number of alloy powder block is:55-60 parts of ferrotungsten, 6-7.5 parts of pureed graphite, vanadium iron 10-12 Part, 5-6 parts of ferrosilicon, 20-25 parts of reduced iron powder.
A kind of alloy powder block production method step for fabricated in situ WC-VC particles enhancing iron-based composite coating of the present invention It is as follows:
Step 1:Prepare powdery starting material according to mass fraction:55-60 parts of ferrotungsten, 6-7.5 parts of pureed graphite, vanadium iron 10-12 parts, 5-6 parts of ferrosilicon, 20-25 parts of reduced iron powder;
Step 2:Powdery starting material is put into batch mixer and is adequately mixed, mixed-powder is made;
Step 3:It is adequately stirred after mixed-powder to be poured into the Arabic gum aqueous solution of a concentration of 2-5%, mixing is made Object;The aqueous solution addition of Arabic gum is 10-25ml in per 100g mixed-powders.
Step 4:Mixture is placed in air dry oven and is heated to 120-160 DEG C, keeps the temperature 2h;
Step 5:Mixture cools to room temperature with the furnace, and the alloyed powder of different size series is pressed into the mold of different model Block.
Wherein, compacting different size series alloy powder block can be used coat briquetting technique cuboid is made, thickness is 2-3mm.Alloy powder block after making vacuum packing machine is encapsulated spare.In use, taking out alloy powder block after sealing off uses tungsten Electrode argon arc welding machine built-up welding.
Alloy powder block of the present invention can react under the conditions of electric arc reaction generates WC-VC particles enhancing iron-based cladding in situ Layer, and the problem of influence the bond strength of WC-VC particles and matrix there is no the dissolving of WC and VC and surface contamination, effectively Improve the wear-resisting property of cladding layer.For the present invention due to being block elements, production method is simple, flexible and convenient to use, with normal Rule welding method welding can obtain WC-VC iron-based composite coatings under electric arc, therefore production cost is low, and WC-VC particles are anti- It should synthesize, be cleaned with matrix combination interface, also avoid the dissolving of particle, the performance of cladding layer has obtained good raising.
The present invention has following significant difference compared with prior art:
1. compared with the hard alloy that powder metallurgy obtains, since matrix is ferrous alloy so that cladding layer has high resistance to Also has good plasticity while mill property.And wear member surface can be overlayed on Integral melting, reach and extends part use The effect in service life.It moreover, application field is more extensive, not only can be used for the whole production of part, but also can be used for repairing for part It is multiple.
2. compared with thermal spraying, the bond strength of WC-VC particles and matrix is more preferable, and distribution of particles is more uniform, surface The porosity of hardness higher, material is low, the utilization rate higher of material.
3. compared with existing cladding method, since WC-VC particles are that reaction in-situ generates, the sinking to the bottom of carbides-free particle, Dissolving, the unclean problem in surface, therefore wear-resisting property are more stablized.
4. low using alloy powder block manufacturing cost with current build-up welding repair method ratio, production efficiency is high, can be used for automatic Change large batch of production, size, the specification of respective series can be made according to the different situations for repairing object in product, easy to use, Fast.
