Description
In the third and final part of a series, results are reported on the thickness of tin coating on 63 steels of various composition. Three tests used to determine the number of discontinuities (pin holes) in the tin coating are also discussed; all specimens were found to tin satisfactorily. Correlations of coat roughness with increasing silicon, and increase in iron-tin alloy layer thickness with increased silicon and manganese, were found. Third of three parts.
