Abstract:
PCT No. PCT/DE97/00453 Sec. 371 Date Sep. 25, 1998 Sec. 102(e) Date Sep. 25, 1998 PCT Filed Mar. 8, 1997 PCT Pub. No. WO97/36112 PCT Pub. Date Oct. 2, 1997A laminated composite material, and a method of improving the surface hardness of laminated composite materials, wherein selected regions of the carrier material of the laminated composite system are treated with high-energy beams, and the temperature control is designed in such a manner that the rays penetrate into a maximum a 0.1-fold the entire thickness of the carrier material. The temperature increase in the region of the sliding material is a maximum of 80% of the melting temperature of the lowest melting constituent of said material. The laminated composite material with a rear steel substrate surface can be post-hardened. The steel substrate has at least in one part of the surface facing away from the function layer a level of hardness increased by a factor of 1.5 or more than at a depth which corresponds substantially to 0.1-fold of the thickness of the steel substrate.
