Abstract: A method applies a titanium aluminide alloy on a substrate. The titanium aluminide alloy has a gamma phase proportion of at least 50% based on an overall composition of the titanium aluminide. The method includes: pretreating a surface of the substrate; heat treating titanium aluminide powder particles at a temperature range of 600° C. to 1000° C. to increase the proportion of the gamma phase; cold spraying the heat-treated powder particles onto the substrate or a part of the substrate to form a layer of titanium aluminide; and thermally post-treating the layer of titanium aluminide applied to the substrate.

Abstract: The invention relates to a carbon-containing nanomaterial comprising, in particular made up as, a network of carbon wall structures which enclose open or closed voids which has a density which can be as low as 0.2 mg per cm3 or lower. The nanomaterial of the invention is made up as a network of carbon wall structures. The carbon wall structures can be tubular, rod-like or in the form of webs or the like which have varying thickness and thus form a network structure, in particular a three-dimensional network structure constructed in the manner of a sponge.
