RESEARCH FOR COATINGS FOR PROTECTION OF NIOBIUM AGAINST OXIDATION AT ELEVATED TEMPERATURES. Quarterly Report No. 3 for January 1, 1958 to March 31, 1958
S>The investigation has been concerned with the utilization of flame- spraying of metal powders and electrodeposition as techniques for the application of oxidationresistant coatings to niobium for use at temperatures above 2500 d F in air. Conventional powder spraying techniques were employed in the deposition of a number of alloy powders. Oxidation tests conducted on several coated specimens at 2500 d F indicated that although certain of the alloys show promise insofar as oxidation resistance is concerned, much remains to be accomplished in the development of a consistent procedure for the application of the coatings to niobium. The factors affecting the quality of flame-deposited alloy coatings as produced were evaluated on the basis of a few tests. The work is being continued along the same lines.
