 | This report describes the results of the plating and evaluation of these in terms of their effect on the plating process. In concluding the work with radioactive tracer, some tests were made on the Chrome-Alum bath using radioactive Cr+3 as a tracer. Although not conclusive, the results indicated that the Cr+3 ion was the main contributor to the plate. To complete the comparison between the Chrome-Alum bath and chromic acid ... |

| The object of this projects is the investigation of the fundamental principles of chromium plating baths from the standpoint of thermodynamic theory. Experimental work has been continued in an attempt to correlate theoretical equations developed from reaction rate theory with the actual plating processes. These equations have been further adapted to apply to the plating of chromium from chromic acid. It has been possible to obtain consistent data at varying ... |

| Standard thermodynamic functions have been evaluated for a postulated chain of reactions for the plating of chromium from chromic acid. The main basis for eactions and data are taken from the existing literature on the subject. It has been shown that an adaption of the theory will be required before a complete theoretical analysis is possible. Experimental work has been directed toward possible tests of the theory as proposed. Review ... |

| The third Progress Report for this project described studies of the migration rate of constituents in the chromium-plating bath. The results of these studies indicated that the experimental techniques then in use would not allow proper evaluation of the effect of sulfate and trivalent chromium in the chromium-plating bath. Experimental work has continued along the lines of studying the disposition of trivalent chromium in chromic acid solutions. A method has ... |

|
| 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 ... |
