FIELD: manufacture of substrate with layer of carbon-alloyed titania acting as photo-catalyst sensing visible light.
SUBSTANCE: method comprises steps of heat treatment in order to provide temperature of surface of substrate having at least surface layer containing titanium, titanium alloy or titanium oxide in range 900 -1500°C. Heat treatment of substrate surface is realized by directing flame of burning gas including, mainly hydrocarbon directly on substrate surface or in atmosphere of gaseous combustion products of gas containing mainly hydrocarbon in order to form carbon-alloyed titania layer. Heat treatment of substrate surface may be realized in gaseous atmosphere containing mainly hydrocarbon or hydrocarbon with air or hydrocarbon with oxygen.
EFFECT: possibility for producing substrate with layer of carbon-alloyed titania characterized by increased useful time period, high hardness, resistance against scratching, improved wear resistance, chemical stability and thermal stability.
