Such as described, make crust with Co base alloy, as powder filler (being filled in the powder of outer intracutaneous), by W 2The powder of interpolation BC and the powder of FeSi are made composite filament in the hard particles (particle diameter is 44 μ m to 65 μ m) that C constitutes.Thus, composite filament as a whole can self-fluxing natureization (eutectic is revealed).The chemical constitution of the composite filament of Zhi Zuoing like this, shown in the embodiment 10 of table 1 like that.The contriver finds when by W 2When interpolation BC compound powder and FeSi compound powder made described composite filament carry out self-melting alloy in the powder that the C hard particles constitutes, self carry out high rigidityization deposited metal.By in the composite filament that constitutes by Co base alloy, adding boron and silicon, can make W as hard particles 2C is dispersed in the deposited metal expeditiously, because the parent phase self of alloy carry out high rigidityization, improves compactness so the interior void content of tunicle is diminished, and can form the good tunicle of wearability.
[effect validation test]
The contriver has implemented to make with SiO in order to investigate the anti-slurry erosion of base material and various arc spraying materials 2For the slurry erosion that the sand of main component is sneaked in the clear water is tested.Experiment condition: the median size of sand is that the concentration of 5 μ m, sand is 1kg/m 2, sand angle of attack be below 15 °, the relative impact velocity of sand is 55m/s.Fig. 5 represents the Vickers' hardness of base material and various arc spraying materials and the relation of slurry erosion injuring speed.Fig. 5 shows that Vickers' hardness increases more, and anti-slurry erosion is high more.When with original W that contains 2The Ni matrix alloy of C hard particles is relatively the time, embodiments of the invention 7 contain W 2The Ni base self-melting alloy (crust self becomes the situation of self-melting alloy) of C hard particles, Vickers' hardness has increased, and anti-slurry erosion has improved.The hard particle diameter of usually wishing deposited metal is identical with the particle diameter of sand in being contained in rivers and creeks water.In addition, in arc spraying, blow the molten drop that flies composite filament and the mechanism of fused ceramic particle not owing to become with air nozzle, so when ceramic particle diameter is below the 150 μ m, ceramic particle disperses to periphery, therefore, the spraying plating efficient step-down of the ceramic particle in the deposited metal.In addition, the carbide in being filled in composite filament, for example, WC, W 2Hard particle diameters such as C are 5 μ m when following, and spraying plating efficient is very little, and this has narrated in front.Have, when the particle diameter of carbide etc. being made hour, when arc spraying was constructed, carbide particle self carried out high temperature oxidation again.The inventor thinks, if make without air nozzle, and the nozzle that has been to use reducing gas or nitrogen or rare gas element blows the molten drop that flies composite filament and the mechanism of fused ceramic particle not, even below the particle diameter of the carbide 5 μ m, can prevent that also it from carrying out oxidation when spraying plating.The WC, the W that in the arc spraying that uses common air nozzle, use 2The particle diameter of carbide such as C is preferably more than 5 μ m, below the 150 μ m.
When described ceramic particle diameter is 150 μ m when following, because ceramic particle disperses to periphery, so the spraying plating efficient step-down of the ceramic particle of deposited metal can not obtain desirable wearability tunicle, this has narrated in front.Owing to promptly use the method for self-melting alloyization of the present invention; at the hard particle diameter is situation about tens of μ m; spraying plating efficient is step-down also; so by carry out granulationization with metal or alloy or powder of becoming self-melting alloy etc.; can improve spraying plating efficient, preferably the eutectic of self-melting alloy of the present invention reveal, the diameter of 2 particles of granulationization makes more than the 40 μ m.But, because the oxide compound of oxide diameter sizes can not cause arc spraying the time is rotten, so preferably construct with the particle that the particle diameter of the sand of rivers and creeks water is consistent with particle diameter.
Under various arc spraying conditions, the composite filament of making is carried out the jet erosion test of the sprayed evaluation test of waste field formula under following condition.Fig. 6 represents to investigate the result of the wearability of the various arc spraying materials that obtain.The result shows that in original composite filament, the spraying plating execution conditions have bigger influence to wearability.In composite filament of the present invention, even the condition of the air pressure when changing the spraying plating construction all shows almost fixed advantages of good abrasion.In the situation of considering to be used for impellers such as pump, even the object of complicated shape also shows the constant wearability, this also is effective effect in practicality.
