On the Porosity of Au and Ag Coatings Formed in Earth-Based and Space Conditions

It has been accomplished comparative survey of the structure, substructure and submicro porosity of coatings of fine metals with face-centered cubic lattice Au and Ag being condensed in both conditions of space flights of orbital stations and earth-based conditions. Urgency of such surveys are concerned with the necessity of settling the issues of creation of the advanced technologies for developing and recovery of different coatings-thermostatic, protective, optical etc. in space-based conditions.

Transgranular Pore Formation in Nanocrystalline Coatings Condenced in the “Openess” of Vacuum and Quasi-Closed Volume

It has presented a review of the results of the survey on the formation and behavior of submicropores (SMP) in mono- and poly-crystalline systems, condensed in the “open vacuum” and quasi-closed volume. The mechanisms, patterns and characteristics of these processes, depending on the physical and technological factors are reviewed.
