Abstract

1365680 Molybdenum-aluminium alloy powder MUREX Ltd 12 Oct 1971 [12 Oct 1970] 48401/70 Headings C7A, C7D and C7F A molybdenum-aluminium alloy powder containing 2À5-50% Al has a tap density of at least 35% of the theoretical density, at least 80% of the particles have no axis through their centre of gravity more than twice the length of any other axis and a particle size of 10-150Á. The alloy may be prepared by heating Mo metal and Mo oxides with sufficient Al to reduce the oxides and provide the Al required for the alloy. The powder may be used for coating by spraying using e. g. plasma equipment or oxygen-fuel flame spraying. The coating may be followed by coating with stainless steel.
