  • Laser irradiation induced non-skid surface layer formation on substrate
    Patent number: 6344246
    Abstract: Robotic cladding of an underlying substrate with a composite metallic surface layer on a prepatterned interface with the substrate, is performed by a laser induced surface improvement process whereby a particulate ceramic additive introduced into a matrix mixture forms the surface layer with a permanent non-skid property bonded by intermixing of molten portions of such matrix mixture and the substrate at the interface, enhanced by prepatterning of such interface.
