Title:
METHOD FOR PRODUCING A COATING MADE OF POWDERED MATERIALS AND DEVICE FOR REALISING THE SAME
Document Type and Number:
WIPO Patent Application WO/2000/028110
Kind Code:
A1
Abstract:
The purpose of the present invention is to improve the physical and chemical properties of a coating made of various powdered materials and to improve the application process efficiency. This method is characterised in that, before supplying a gas-powder mixture to the acceleration nozzle, said mixture is previously accelerated to a predetermined speed using a gas which is inert relative to the starting powdered material, and further fed into the core of the working-gas acceleration flow. The device includes a pulverisation unit in the form of a supersonic acceleration nozzle comprising a linear section, at its outlet, which turns into a curved-surface section. The device also includes an intermediate supersonic nozzle which is arranged coaxially relative to the acceleration nozzle and is capable of reciprocating movement in the subsonic portion thereof.
