LASER SUFRACE REMELTING OF HVOF SPRAYED Co-Cr-W COATING
Original language description
The technology of Laser Surface Re-melting (LSR) is used to modify the surface layer of bulk materials or coatings in order to improve their surface properties, usually wear resistance. In the case of thermally sprayed coating, its application leads to elimination of porosity and internal oxides on the coating splat boundaries. The increase of corrosion resistance and inner cohesion strength of the coating is expected as a result of laser post-treatment. In the paper, the Co-Cr-W HVOF sprayed coating was subjected to the series of LSR procedures with varying laser parameters to study their influence on the thickness of remelted layer. The laser power and processing speed was the main studied parameters. The optimal parameters for LSR of coating with given thickness were found. Besides the laser parameters, the influence of spraying procedure, namely the procedure of grit blasting, on the creation of cavities in the remelted coating is discussed.
