Abstract

Dispersion kinetics which is proceeds in chromium and nickel nanofilms by thickness of 100 nm deposited onto oxygen-free inorganic materials as a result of them annealing in vacuum at temperatures 1000—1200 °С during various time (2—20 min) is investigated. It is established that both metal films onto carbon glass and Si3N4 ceramics are completely disintegrated at 1200 °С besides nickel film also interact with the substrate material. These films onto Si3N4 and carbon glass can be used for brazing at temperatures up to 1100 °C.
