Rhenium Alloys - Iron Group Metals (Electrodeposition and Properties)

摘要

The electrodeposition of thick deposits of rhenium co-deposited with the iron group metals (binary systems) from various electrolytes has been investigated. Microstructures of some of the alloys are shown and some of their properties have been evaluated and discussed. The behavior of the alloys (15-45 weight per cent Re) after heat treatment at temperatures ranging from 600-1800F have been studied and the microstructural and microhardness changes are presented. Crystallography of the Co-Re system before and after heat treatment is also discussed. The effects of inert sub-micron sized dispersoids of Al203 on the microstructure and properties of Co-Re alloy coatings is presented. (Author)
