Abstract:

The 94 per cent chromium - 6 per cent iron alloy plate 0.003 inch thick has been successfully applied to the bore surface of 12-inch sections of 40-mm. gun tubes. Though adhesion was generally good, as indicated by resistance to peeling upon sawing, there was some indication, by metallographic examination, of need for further improvement. Attaining good adhesion is no problem when plating flat panels. So, the internal moving-anode system will be studied further. The process for alloy plating the bore surface has been simplified by modification, eliminating the porous diaphragm that was previously needed.
