摘要： The invention relates to nozzles for plasma torches, which are essentially formed from a metal or a metal alloy. Particularly during the operation of such plasma torches for cutting processes using oxygen, an increase in wear occurs on the nozzles, which have to be exchanged with corresponding frequency. It is, therefore, the object of the invention to increase the life of such nozzles. According to the invention, this object is achieved in that wear-resistant microparticles of a hard material, preferably a hard ceramic material, are embedded in the metal or the metal alloy, at least in certain regions. The nozzles can be advantageously manufactured by extrusion.

摘要： An electrode element for plasma torches and a production method for such electrode elements. The electrode element for plasma torches includes at least one core which is made of a metal or a metal alloy having a smaller work function, and forms the actual electrode connected as a cathode. This core is enclosed by a shell part which is made of a metal or a metal alloy having a greater work function and thermal conductivity. Between the core surface and the shell part there are provided a boundary layer in a graded form, which is made up of solid solutions of the two metals or metal alloys, or an intermediate layer toward the core surface and toward the shell part, which is made of another metal or a metal alloy having a work function being greater than that of the core material wherein the boundary layers of the intermediate layer form a graded transition.

摘要： A rubber-based soundproofing material comprises a mixture of a rubber blend, a metal or its oxides, alloys or salts, and conventional mixing ingredients. The mixture is either a non-blended chlorobutyl rubber, bromobutyl rubber or acrylate rubber, or a blend of nitrile rubber or styrene-butadiene rubber with epoxidized natural rubber. The mixture has the following proportions: 10-15% by wt. rubber or rubber blend, 85-40% by wt. metal or its oxides, alloys or salts, and 5-10 wt. % mixing ingredients.
