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 method for connecting substrates including depositing a plasma polymer layer on each of a first and a second substrate by means of atmospheric pressure plasma and bringing the plasma polymer layers in contact with each other. In a variant of the method, only the first substrate is provided with a plasma polymer layer and connected to a second substrate, the surface of which can react with the plasma polymer layer. The invention further relates to composite structures which can be obtained with such methods.
