Sintered titanium-molybdenum compacts have the high corrosion resistance in nonoxidizing acid solution, as already reported in part I.<BR>In this time, an experiment on the corrosion resistance compared with tantalum, which is an expensive and corrosion resistance metal, was carried out. The experiments on the improvement of the mechanical properties of the sintered Ti-30Mo compacts and also the effects of nitriding and additions of titanium carbide and titanium nitride for the improvement of wear resistance were carried out.<BR>The results obtained were as follows;<BR>1) On mixing methods, a mixing method without crushing was much better for the mechanical properties of sintered Ti-30Mo compacts.<BR>2) Improved mechanical properties of sintered Ti-30Mo compacts were obtained by the vacuum sintering in a carbon vessel.<BR>3) The mechanical strength of the sintered Ti-30Mo compact obtained reached to 170 Kg/mm2 in transverse rupture strength and 75 Kg/mm2 in ultimate tensile strength.<BR>4) Good corrosion resistance of the sintered Ti-30Mo compacts was superior obtained in hydrochloric acid and sulfuric acid, as well as that obtain in tantalum.<BR>5) The additions of titanium carbide and titanium nitride were effective to improve the wear resistance.
