Abstract
An admixture of unalloyed powders for forming strong, oxidation-resistant bodies or coatings has a composition, in atoms per cent, within the range: .Mo, W, Ta, Nb and/or V.10-40 .Si.20-65 .Cr, Ti and/or Zr.2-16 .B.2-25 .Al.3-30 B may be introduced as a boride of Cr, Ti and/or Zr. The mixture may be used for forming self-sealing coatings, resistant to oxidation at high temperatures on carbon, tungsten, molybdenum and other refractory metals and their alloys, particularly for components of turbo-jet engines. The mixture may be applied as a coating by means of a spray gun using an oxyacetylene flame, the powder being aspirated into the flame using an argon stream passing through a powder dispenser. The coating so applied requires heat-treatment, e.g. at 1100 DEG C. for 3 hours in a hydrogen atmoshere to remove porosity. The mixture may also be applied by detonation or by dipping, painting or spraying in the form of a slurry followed by heat treatment in an inert atmosphere. Sintered bodies may be formed by hot pressing in a carbon die e.g. under 2000-3000 pounds/sq. in. at 1500 DEG C. for 15 minutes. Specifications 742,387, 742,458, 742,459 and 742,460 are referred to.
