Abstract
In an attempt to improve the oxidation resistivity of sintered tungsten compacts, effects of chromium content on the oxidation resistivity, transverse rupture strength and hardness have been studied in the sintering activated by paladium.
1) The best oxidation resistivity was obtained with alloys containing 20 wt% chromium, and weight gain at 1200°C was 5mg/cm2 for this composition.
2) Transverse rupture strength and hardness decreased with increasing chromium content.
