Abstract

Porous structure and outer surface, electronic structure and cluster composition of diamond like films in dependence on film thickness are described. Transparence in the 0.3 - 25 micrometers region, corrosion resistance, and microhardness are also investigated. Diamond like films were obtained by different plasma-ion methods. The thickness of the films covered the range from 3 to 50.0 nm. The thickness of separate layers in multilayer structures was 5.0 - 10.0 nm. It has been shown that multilayer protective coatings based on (alpha) -C:H films allows the user to decrease summary thickness of the coating to raise beam resistance in comparison with one layer coatings in 1.5 - 1.8 times. Service life of a mirror with protective coatings is no less than 3 times more than for mirrors without protective coating. When changing properties and thicknesses of layers in multilayer coatings selective reflection multilayer mirrors and one-layer steering mirrors for the soft x-ray region have been created.
