A Research Investigation of Fundamental Factors Governing the Ductility and Hot Hardness of Electrodeposited Chromium.

Abstract

Progress has been made in the development of experimental techniques for measuring basic effects associated with common constituents of chromium-plating baths. Further refinement is needed before data can be procured for translation into plating bath modification to apply crack-free chromium. The successful application of chromium plate to large-caliber gun tubes requires improvement over commercial plate in terms of freedom from cracks and retention of hardness at high temperature. The experimental program is continuing a study of a recent fundamental theory for the mechanism of chromium plating and for the characteristics of the chromium plate. This shows that the cracks, hardness, and surface appearance are determined by the amount of hydrogen present in the 'as-deposited' chromium crystal structure.
