In order to accelerate the sintering of Al-bronze powder covered with the oxide film in the hydrogen atmosphere containing high amount of nitrogen, we added phosphorus in the form of the phosphorus alloy in addition to Al-Ca fluoride the effect of which we reported in the previous paper. Al-bronze powder which was well sintered and formed the sintered compacts with higher strength even in the atmosphere containing high amount of nitrogen was obtained by adding over 0.2 mass% phosphorus. In the wear test of the above sintered compacts, it was found the dynamic friction coefficient and the wear rate of the Al-bronze sintered compacts were nearly half of those of Sn-bronze, and furthermore the wear rate of the Al-bronze sintered compacts decreased remarkably by dispersing 3 mass% of graphite.
