Preliminary Development of Spectrochemical Analysis of Superalloys with the Liquid-Layer Solid-Sample Spark Technique
Abstract
A comparison study is made, for the spectrochemical analysis of cobalt-base superalloys, between the liquid-layer solid-sample spark technique and the conventional point-to-plane spark analysis in air. The changes of analytical concentration curves are indicated for alloying constituents of two developmental cobalt-base alloys, and correlation of the changes to preliminary microscopic, metallographic, and spectroscopic phenomena are hypothesized.
