Abstract: An implant comprising an implant material forming a base made of one or more metallic elements; a diffusion layer covering the base made of at least one of the metallic elements of the implant material and at least magnesium; and, optionally, a metal layer covering the diffusion layer made of magnesium or a biocorrodible magnesium alloy.

Abstract: Unique labels for security or identification purposes, methods of making the labels and uses for the labels are described herein. The label is formed from one or more crystalline materials, optionally in combination with a non-crystalline material, or from a combination of polymers, and has a unique, detectable pattern. In one embodiment, the label is formed from a crystalline material, preferably a metallic material, which naturally contains a unique grain structure, with unique reflective properties. In a preferred embodiment, the label is formed of a metallic material that has been recrystallized to enlarge the size of the grains so that they are visible to the unaided human eye.

Abstract: A fully martensitic quenching and tempering steel (AP) essentially consists of (measured in % by weight): 8 to 15% of Cr, up to 15% of Co, up to 4% of Mn, up to 4% of Ni, up to 8% of Mo, up to 6% of W, 0.5 to 1.5% of V, up to 0.15% of Nb, up to 0.04% of Ti, up to 0.4% of Ta, up to 0.02% of Zr, up to 0.02% of Hf, at most 50 ppm of B, up to 0.1% of C and 0.12-0.25% of N, the content of Mn+Ni being less than 4% and the content of Mo+W being less than 8%, the remainder being iron and usual impurities resulting from smelting.

Abstract: The heat- and creep-resistant steel has a martensitic microstructure produced by a heat-treatment process. The composition of the steel in percent by weight is as follows:0.001-0.05 of carbon0.05-0.5 of silicon0.05-2.0 of manganese0.05-2.0 of nickel8.0-13.0 of chromium0.05-1.0 of molybdenum1.00-4.0 of tungsten0.05-0.5 of vanadium0.01-0.2 of niobium2.0-6.5 of cobalt0.1-0.3 of nitrogen,the remainder being iron and unavoidable impurities. Such a steel can be produced by forging, casting or by powder-metallurgical means. Components fabricated from this steel show a high strength and ductility at room temperature and are distinguished at temperatures of 600.degree. C. and higher by a very high creep strength and an unusually high oxidation resistance. They can therefore be used with advantage as mechanically and thermally highly stressed components in steam- and/or gas-operated power stations.
