Titanium hydride powder, manufactured by ball milling titanium in a hydrogen atmosphere down to micron-sized particles, was analyzed by X-ray Photoelectron Spectroscopy (XPS). A strong titanium oxide signal was also measured, which decreased somewhat after intense sputtering of the sample, but was impossible to get rid of completely. Auger Electron Spectroscopy (AES) was then employed and some characteristic differences in the shape of the Ti LMM spectra between the TiHx and Ti were observed.

In this work, the viability of dolomite powder as cost-effective alternative to TiH2 foaming agent was investigated. Closed cells aluminium foam samples were prepared starts from solid, foamable precursors synthesized by powder metallurgy and melt route. Precursors obtained by melt route were machined and additional cold isostatic pressed in order to improve their density. In all cases, the resulted precursors consisted of an aluminium matrix containing various mass fractions of uniformly dispersed dolomite powders of various average particle size and 5 % of SiC particulates.
