FIELD: chemistry.
SUBSTANCE: present invention relates to a method of coating a substrate (2), having on its surface a material different from silicone rubber, or consisting of such material, by chemical vapour deposition using a flame. The method includes exposing the substrate to a burner flame (1), to which a stream of precursor elements which enable to obtain coating material is added. Without external cooling, the substrate is moved relative to said flame with a relative speed greater than 30 m/min while allowing the flame to stretch along the reaction zone (3) located behind the burner.
EFFECT: obtaining a coating of good quality, particularly on heat-sensitive materials.
