CVD tungsten - rhenium alloy corrosion behavior
Technical Report
·
OSTI ID:6198948
The chemical and electrochemical corrosion behavior of chemical vapor deposited tungsten-rhenium alloy has been studied using nitric and sulfuric acid mixtures to remove the deposition substrate. The alloy corrosion rates as a function of acid composition, aeration, and temperature were established. Computer-aided analysis of polarization data showed that the tungsten-rhenium etched faster in dilute nitric acid solutions. The logarithmic etch rate was proportional to the reciprocal of the etchant temperature. Selective etching of the surface was more severe for alloys with an excess of eighteen weight percent rhenium. Protective coatings were studied and their respective merits are considered.
