Document Type and Number:
Japanese Patent JPH11505292
Kind Code:
A
Abstract:
The invention concerns a method of coating a base with a plasma-sprayed layer with a spray powder contained in the molten state in the plasma. In the proposed process, the powder is introduced via powder feed ducts in the vicinity of the neutrode(s) or anode(s) or between the two into a channel of a plasma spray device, at least one arc being at least 20 mm in length at least some of the time and the base to be coated being a so-called continuous strip or large-surface unit of at least 0.005 m<2>. The invention also concerns a device for coating a base, comprising a number of plasma spray devices and at least one noise-protection cabinet; the plasma spray devices each comprise at least one neutrode and at least one anode for producing an arc of at least 20 mm in length and for heating a spray powder. The spray powder is introduced in the vicinity of the anode(s) or neutrode(s) and/or between the two, and the device is provided with a device for micro-roughing the article in the form of a mechanical, physical or radiation micro-roughing unit.
