摘要:
A compound substance of great hardness and toughness, comprising a metal matrix, having embedded therein, hard material granules of a size of 0.1 to 5 mm. The metal matrix comprises 1 to 4% carbon, 0.3 to 0.6% silicon, 0.5 to 1.5% manganese, 0.8 to 2.8% vanadium, 0.5 to 1.5% chromium, 2 to 10% tungsten, about 0.01% aluminum and the remainder, iron.
摘要:
Particles are sinter-fused onto the surface of a prosthesis shaft of titanium or titanium alloys. Before sinter-fusing, a coating material which forms below the .alpha.-.beta.-transition temperature a liquid phase with the material of the prosthesis and particles is applied to provide a coating between the shaft and particles.
