Abstract: The invention relates to a method for modifying piece surfaces consisting in bringing pieces into contact with at least one type of a modifying agent in such a way that the modification of the surface is carried out.

Abstract: The invention relates to a thermal spraying method, in particular for coating a surface by means of a plasma beam, using a shaped plasma beam, wherein a first plasma beam by means of at least one second plasma beam is controlled and/or shaped, wherein the second plasma beam at least partially and at least temporarily penetrates the first plasma beam.

Abstract: The aim of the invention is to provide a fluxing agent for soldering components, which creates one or more specific surface characteristics during the soldering process itself, thus obviating the need for the surface treatment process that is conventionally carried out after the soldering process. To achieve this, nanoparticles are added to a base substance.

Abstract: A conducting device, such as a corrugated fin, for a heat exchanger, has at least one surface with an increased microscopic roughness. A method increases the microscopic roughness of at least one surface of a conducting device such as a corrugated fin. A heat exchanger, such as an evaporator for an air-conditioning system of a motor vehicle, has tubes through which a medium flows and between which conducting devices are arranged, the conducting devices having a further medium, such as moist air, flowing around them.

Abstract: The invention relates to an apparatus and a process for the preferably uneven application of flux to a material surface, in particular to the finned side of a plate of a plate-type radiator.

Abstract: The invention relates to a surface of an object, especially a heat exchanger, e.g. a lateral part, a wavy rib, or a tube of a heat exchanger, which is to be soldered by means of a flux layer (2). In order to improve the properties of the surface that is to be soldered, said surface is provided with at least one more layer (3; 13, 16) in addition to the flux layer (2). The at least one more layer (3; 13; 16) contains an additive which modifies the surface to be soldered, said additive being reacted in order to modify the surface when the surface that is to be soldered is soldered.

Abstract: The invention relates to a conducting device, in particular a corrugated fin, for a heat exchanger, having at least one surface. In order to improve the efficiency of heat exchangers, in particular of evaporators, the surface of the conducting device has an increased roughness, in particular microscopic roughness.

Abstract: The invention relates to a method for producing a plastic part. According to said method, a plastic mass is heated to a moulding temperature which is equal to or higher than a melting temperature. Said plastic mass can be moulded by heat from the melting temperature. Plastic mass is moulded when it has reached the moulding temperature, the temperature of the moulding part is adjusted to a conversion temperature which is dependent on the type of plastic and which is lower than the melting temperature, and the moulded part is maintained at a conversion temperature for a defined conversion time frame. The invention also relates to a device comprising a plastic part which is produced according to said inventive method.
