Abstract
The present invention provides an alloy powder which possesses high red-hardness and can resist high-temp.wear and corrosion. Said alloy powder can be used for plasma surfacing and laser deposition or oxyacetylene overlaying welding of air valve in place where the valve sealing surface, etc. require to resist high-temp. wear and corrosion instead of partial cobalt base alloy powder.
Description
The present invention relates to field of new, particularly surface strengthening is worn and torn and the resistant alloy powder with high temperature resistance.
Usually, the surface consolidation material that uses at comparatively high temps (＞600 ℃) is stellite based on cobalt base alloy, but the cobalt metal is rare strategic materials, should the least possible application.
At above situation, the present invention has added the part cobalt molten the carrying out in the material of nickel base surface, higher tungsten and molybdenum element and rare earth Re have suitably reduced boron, employing is than low carbon content, do not add aluminium and titanium, adjusted chromium content, and obtained the powdered alloy of following composition ((wt) %): all the other are Ni to Re＜1.5 (for example 1.0) B 1.0～1.2 (for example 1.0) Si 2.2～2.5 (for example 2.3) Mo 3.5～4.5 (for example 4.0) C 0.9～1.1 (for example 1.0) W 4.0～5.0 (for example 4.5) Co 12.0～16.0 (for example 14.0) Cr 22.0～24.0 (for example 23.0).
The powdered alloy of the above composition of the present invention has the red hardness of height (≤700 ℃), anti-higher temperature (≤700 ℃) wearing and tearing and corrosion, saved rare strategic materials cobalt, can plasma spray, laser deposition technology and oxygen-acetylene repairing are used for valve, valve sealing faces etc. require high temperature resistance wearing and tearing and corrosive occasion, and can partly substitute Co-based alloy powder under such condition.
