The invention relates to the use of a carbonaceous coating for protection of a passive electrical component from attack by ammonia, wherein the carbonaceous coating is a sol-gel coating or a plasma-polymeric coating. This coating comprises a particular carbon content.

Use of a carbonaceous coating for protecting a passive electric component from attack by ammonia and system comprising a passive electrical component, which is protected against attack by ammonia

The invention relates to a passive electrical component, especially a coil, having an interlayer, wherein the interlayer has a lower coefficient of thermal expansion than the surface of the passive electrical component covered with the interlayer, and disposed atop that a plasma-polymeric carbon-containing coating having a carbon content measured at a depth of 80 nm away from the side of the plasma-polymeric coating remote from the interlayer, wherein the plasma-polymeric coating comprises a carbon content of 50 to 100 atom %, preferably 50 to 90 atom %, or is configured as an organometallic coating a carbon content of 2 to 50 atom %, in each case measured by means of XPS.

Passive electrical component with coating to improve the loading capacity

The invention relates to a removable anodizing agent, in particular for local anodic oxidation of metal surfaces, and its use, and a method for anodic oxidation by means of an anodizing agent according to the invention.

Removable anodising agent, in particular for local anodic oxidation of metal surfaces

A device for testing the quality of microstructurization of a surface () having a known target microstructurization quality, comprising a radiation source () for coherent radiation, a first detector () and a second detector () and a masking system, all of which are set up and arranged with respect to one another so that radiation emitted by the radiation source () onto the surface () produces a diffraction pattern, wherein the diffraction maximum of order n of the diffraction pattern without the masking system would impinge on the first detector (), the masking system prevents 80% of the photons that are assigned to the diffraction maximum of order n from impinging on the first detector and the diffraction maximum of order a of the diffraction pattern impinges on the second detector (), wherein n is selected from the group consisting of 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 and a is selected from the group consisting of 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 and a&#x2260;n.

Device for testing the quality of microstructurization

In a process according to the invention and an apparatus according to the invention for the coating or modification of a surface a flow of a first gaseous phase or of a first aerosol comprising one or more precursor compounds is guided along a heated filament so that the precursor compounds are converted into reactive compounds. Alternatively, non-activated particles are guided along a heated filament so that these are activated and are then combined with a gaseous phase or an aerosol comprising a plurality of precursor compounds, so that the precursor compounds are thereby converted into reactive compounds. The reactive compounds formed according to at least one of the two aforementioned steps are guided onto a substrate that is exposed to atmospheric pressure, so that a layer is deposited on the substrate or its surface is modified.
