摘要： The invention relates to wear-resistant materials and molded bodies which can be utilized in many fields. Molded bodies made of a hard-metallic, wear-resistant material are known (semifinished products such as prefabricated parts) which are made from a sintered body produced using a powder metallurgical process. To this end, a mixture is produced which is comprised of a hard alloy powder and a bonding agent. Using extrusion molding or metal injection molding methods, the mixture is molded into a green compact of the desired molded body which is subsequently sintered. According to the invention, a pulverized hard material, preferably based on carbide, is admixed as an additional starting product to the metal powder of the hard alloy. This metal powder mixture is mixed with the bonding agent into a paste, said bonding agent preferably being a thermoplastic material with common additives.

摘要： A process for the production of hard materials wherein hard constituent powders are coated with cobalt and/or nickel metal in solution by reducing the metals from a suitable compound such as an oxide, hydroxide or salt with a polyol while keeping the powder in suspension. The polyol functions both as a solvent and a reducing agent at the same time and is present in an amount of at least 5 times more moles polyol than moles metal. There is obtained an even distribution of the cobalt and/or nickel over the surface of the hard constituent powder without the formation of islands of pure metal.

摘要： A dense cermet article including about 80-95% by volume of a granular hard phase and about 5-20% by volume of a metal phase. The hard phase is a carbide, nitride, carbonitride, oxycarbide, oxynitride, or carboxynitride of a cubic solid solution selected from W-Ti, W-Hf, W-Nb, W-Ta, Zr-Ti, Hf-Ti, Hf-Zr, V-Ti, Nb-Ti, Ta-Ti, or Mo-Ti. The metal phase consists essentially of a combination of nickel and aluminum having a ratio of nickel to aluminum of from about 90:10 to about 70:30 by weight, and 0-5% by weight of an additive selected from titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, cobalt, boron, and/or carbon. The article may be produced by presintering the hard phase - metal phase component mixture in a vacuum or inert atmosphere at about 1475°-1675°C, then densifying by hot isostatic pressing at a temperature of about 1575°-1675°C, in an inert atmosphere, and at about 34-207 MPa pressure. Limiting the presintering temperature to 1475°-1575°C and keeping the presintering temperature at least 50°C below the hot pressing temperature produces an article of gradated hardness, harder at the surface than at the core. In this gradated product, the hard phase may alternatively be a carbide, nitride, carbonitride, oxycarbide, oxynitride, carboxynitride, or boride of an element selected from Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, or B.
