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.

Method for producing pieces having a modified surface

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.

Fluxing agent for soldering metal components

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.
