Abstract: The invention pertains to a method for the production of an anode for X-ray tubes, and the invention also pertains to the resulting anode. In the invention, a coating that emits X-ray radiation is applied by inductive vacuum plasma spraying onto the base element. Using this method, an improved fatigue crack resistance and a reduced roughening of the coating on the anode is achieved.

Abstract: The manufacture of powdered feed materials for hard fine grained metal body production includes the reduction of metal oxides into powdered metal and the subsequent carburization into metal carbide. Processes currently used are very cost intensive, mainly because of very long reaction times at high temperatures. According to applicant's economical process, the above reactions occur in the range of seconds and in a high-temperature cyclone as the reaction chamber. The apparatus is rather simple to construct. The stock to undergo reaction is continuously introduced into the chamber as a solid powdered phase with reaction gas and/or carrier gas, and passes through the chamber on predetermined paths for reaction, without leaving the solid state thereby.

Abstract: Structural units which come into contact with glass melts and ceramic melts are exposed to strong corrosive attack. Molybdenum is a known material for glass melt electrodes but it is not usable for the majority of highly corrosive glass and ceramic melts. The use of a special molybdenum and/or tungsten alloy as the material for the structural unit reduces corrosion even in the case of contact with highly corrosive glass and ceramic melts.

Abstract: The invention relates to the application of molybdenum alloys, which are superficially hardened by means of nitriding, for female dies and comparable construction components for extruding light and nonferrous metals. It is possible through the application of these materials to achieve distinct improvements over the materials used heretofore with respect to the tool life, extrusion rate and surface quality of the extruded material.

Abstract: A process for the manufacture of a cooling unit particularly for fusion reactors. The cooling unit consists of one or more parts made of heat-resistant material, preferably graphite, which are joined to at least one metallic coolant conduit, preferably made of copper or a copper alloy. The joint is produced by bringing molten metal of the coolant conduit into contact with the parts made of heat-resistant material. One or more metals of the secondary groups IV and/or V of the periodic table are introduced at the contact surface between the coolant conduit and the heat-resistant parts. The metal of the coolant conduit is thereafter cooled to solidify the coolant conduit in the desired shape.
