Rotating Bands for Artillery Shells.
Abstract
This report summarizes the work completed during a preliminary investigation of the applicability of the LAYERGLAZE (trade name) process to the fabrication of copper rotating bands on titanium artillery shell bodies. Two approaches were taken, one involving direct deposition of Cu onto the Ti alloy bodies, and the second involving the use of a compatible interlayer between the Cu and the Ti. Attempts to bound pure Cu to Ti produced deposits of varying densities but none adhered soundly to the Ti substrate. Of the interlayers investigated, Al had the best characteristics, but often melted and mixed when the higher melting Cu was applied to it. Copper alloys were then investigated, in an attempt to improve coupling, increase deposit density, and reduce substrate temperature. Cu-1% Pb appeared to be well-suited for LAYERGLAZE band fabrication, but the structure did contain some cracks. Although additional development work is necessary, significant progress was achieved, and the process exhibits real potential as an alternative approach for depositing rotating bands onto alloy shell casings.
