Thermophysical properties of porous Ti2AlC and Ti3SiC2 produced by powder metallurgy

The physicochemical properties of porous Ti2AlC and Ti3SiC2 MAX phase compounds with controlled porosity grain size obtained by powder metallurgy techniques was studied in depth order to access their suitability applications such as catalytic devices on vehicles, heat exchangers or impact resistant structures. study performed isostatic consolidated samples different amount (20–60 vol%) space holder (250–1000 µm) without holder. Oxidation tests were at temperatures for each material depending maximum service temperature. In understand the oxidation mechanism, kinetics analysed determine influence case. addition, microstructure composition oxide layers formed after scanning electron microscopy (SEM). Electrical thermal conductivity where room temperature up 1000 °C. effect pore cell wall thickness is discussed. Permeability foams also measured. micro macro permeability coefficient expiation measured all produced. It established that these phases have suitable use substrates, exchanges, high filters volumetric solar receivers.
