Abstract
A special-purpose powder for laser deposition is disclosed, and features high red-hardness, distinct antiwear performance and adaptible to laser deposition for wide power range.
Description
The present invention relates to field of new, particularly special powder for laser deposition.
At present, the laser cladding powder adopts thermal spray powder mostly.But, the natural characteristics of laser cladding makes heat spray self-fluxing alloy powder be difficult to adapt to, particularly the power major part because of the used laser cladding laser apparatus of present China is all lower, so that continue to use the resulting overlay of hot spray powder and great tearing tendency occurs, seriously influenced the normal development of the such new and high technology of laser cladding in China.
For addressing the above problem, the present invention adds boron in the cobalt-based powder, rare earth (Re), nickel, tungsten, molybdenum, carbon and chromium content have been carried out suitable adjustment, and all the other are Co to have obtained Re＜1.0, new powdered alloy C 0.5～0.7 (for example 0.6) B 0.4～0.6 (for example 0.5) Si 1.0～1.5 (for example 1.2) Ni 10.0～12.0 (for example 11.0) W 4.0～6.0 (for example 5.0) Mo 3.0～5.0 (for example 4.0) Cr26.0～28.0 (for example 27.0) (for example 0.5) of following composition ((wt) %)
The powdered alloy of the above composition of the present invention has shown high red hardness, Tu Chu wearability extremely, and it is deposited to adapt to the wide laser apparatus of power range.
