(DE19610015-A1)      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) m2 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.    USE -   To produce a coated substrate or a substrate-free plasma sprayed layer for mfr. of printing plates, relief printing plates or wetting medium guides in printing, wear resistant layers and bodies (e.g. wear plates for fixing on rolls), for receiving lacquers, adhesive layers or other organic materials or mixts., for application of catalysts, as a catalyst or for mfg. catalysts and/or catalytic devices, for mfr. of adhesive tapes, for mfr. of absorbers in solar collectors, for coating carbon bodies and as wear protection or lubricated protective layers (all claimed).    ADVANTAGE -   The process permits efficient, continuous and uniform coating of large area substrates with layers which have selectable thickness and which can, if desired, be detached from the substrate.
