Abstract: The invention relates to a process for the surface treatment of a component (1) having a curved component surface (3). Material is removed from the component surface (3) along a contour line (9) on the component surface (3) by means of a particle jet (7) which is generated from a particle source (5). At least one of the jet parameters is matched to the contour line (9) in such a way that a desired, in particular homogeneous surface roughness is established along the contour line (9). The invention also relates to a blasting installation (47) for the automated surface treatment of a component (1).

Abstract: The surface of an article with a metallic base body is cleaned. A plasma comprising electrically positively charged ions is generated, and the ions are accelerated toward the article, so that they come into contact with the base body for cleaning purposes. To do this, an electron beam is directed onto the base body. The outgoing flux of electrons which come into contact with the base body is controlled by the base body being connected to a reference potential via a switch of at a fixed, adjustable or regulated frequency.

Abstract: The article of manufacture, in particular a gas turbine blade, can be exposed to a hot aggressive gas. The article has a base body, to which a respective thermal barrier coating is applied in at least one first surface region and in a second surface region. In the first surface region, the coating has a fine structure that is different from the coating in the second surface region. The method for applying a thermal barrier coating to a product includes electron beam sputtering and reactive gas flow sputtering processes.
