METHOD OF PRODUCTION OF MICRO-LAMINAR THERMOSTABLE MATERIALS Russian patent published in 2006 - IPC C23C14/24 

FIELD: production of composites with specific physico-chemical properties in vacuum; designing and production of special-purpose heat-resistant materials for protection of recoverable spacecraft, blades of gas-turbine engines of new generation.

SUBSTANCE: proposed method includes sedimentation of layers on preheated rotating substrate in vacuum. Sedimentation of layers of material is performed by boiling-off material from crucibles at their center-to-center distance of 0.55 to 0.8 of substrate diameter. Distance between crucibles and substrate is equal to 0.55-0.8 of crucible center-to-center distance. Temperature of substrate is no less than 0.3 of melting point of the most refractory material being boiled-off. Level of substrate roughness does not exceed 0.63R_A. At interface of layers, thickness ranges from 0.001 to 0.005 mcm at smooth concentrated change from material of one layer to material of another layer.

EFFECT: wide field of varying structural and physico-mechanical properties of materials; enhanced thermal stability of structure.
