Patent ID: 7238631

Claim:
Composite material ( 10 ) comprising: a substrate ( 1 ) that is at least one of flammable and heat sensitive; and a flame protection coating ( 2 ) on the substrate; the flame protection coating comprising: a base layer ( 3 ) of TiO x applied on the substrate ( 1 ) where 1.5≦x≦1.9; a top layer ( 4 ) of at least one of amorphous and crystalline TiO 2 formed on the TiO x base layer ( 3 ); and wherein a total thickness of the flame protection coating ( 2 ) is in the range of 10-300 nm, wherein the TiO 2 top layer ( 4 ) has a thickness in the range of 10-50% of the total thickness of the flame protection coating, and wherein between the base layer ( 3 ) and the top layer ( 4 ) of the titanium oxide layer ( 2 ) is deposited an electrically conductive intermediate layer ( 5 ) which comprises TiO x with an oxygen content of 0.7≦x≦1.5.
