Abstract
A metallic coating (20) is produced on a non-weldable inorganic substrate (6) by hot-spraying on a hot-sprayed intermediate layer (19) of refractory metal alloy chosen from nickel-chromium alloys and nickel and titanium aluminides. This intermediate layer itself may be deposited on an undercoat (18) of a ceramic chosen from aluminium and zirconium oxides and titanium hydrides, which is formed by hot-spraying on the inorganic substrate (6).
