Platinum Group Coatings for Refractory Metals
Abstract
Oxidation resistant coatings of iridium on rhenium substrates have been produced by chemical vapor deposition from an iridium acetyl acetonate starting compound. The process results in rapid buildup of iridium. Heat treatment to near the melting point of iridium causes the iridium to wet and diffuse into the rhenium surface eliminating porosity and assuring good bonding. These coatings have provided oxidation resistance at temperatures of 1850 C in air. After twenty minutes there was no evidence of deterioration. (Author)
