METHOD OF SHAPING HIGH-MELTING AND CHEMICALLY STABLE MATERIALS Russian patent published in 2005 - IPC

Abstract RU 2252280 C2

FIELD: thermochemical etching.

SUBSTANCE: method comprises etching the surface of articles made of high-melting chemically stable materials by applying the layer of an agent interacting the article material and heating the surface by laser pulse irradiating. The surface of the article is simultaneously affected by the laser pulses and vapors of a volatile composition, which is subjected to the pyrolytic decomposition to produce the above mentioned material. The amplitude of the laser pulse should be sufficient to cause the evaporation of the material.

EFFECT: enhanced adaptability to shaping.
