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 . 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.

Abstract: In a process for plasma spray coating of a substrate using a spray powder which is melted in the plasma, the powder is supplied into the region of the anode(s) or the neutrode(s) or, between these, into a channel of a plasma spray unit, one or more arcs have a length of 20 mm. or more at least intermittently and the substrate is an endless strip or a large surface of at least 0.005 (pref. at least 0.01, esp. at least 0.05) m size. Pref. the substrate consists of a metal or alloy, a plastics opt. contg. filler, a paper-contg. material, a composite material or a composite body, esp. aluminium (alloy), backed aluminium foil or a plastic (esp. polyester) foil. Pref. the coating comprises a material rich in oxide, silicate, titanate, boride, carbide, nitride, metal, metal alloy and/or inorganic pigment, esp. in aluminium oxide, spinel, titanium boride, Al, Ni (alloy) or Cu (alloy). Also claimed are: (i) a plasma spray coating appts.; and (ii) a plate for a printing machine, comprising a substrate and a plasma sprayed layer.
