A Study of the Performance of Various Metals as Igniter Contact Rings on the Five Inch SSR Rocket Motor

Abstract

Fourteen metals were examined with respect to the influence of exposure on their electrical contact resistances. None of these bare metals performs with satisfaction after exposure to high humidity and to salt spray. Several organic coating materials were also investigated to determine whether they improve the performance of these metals. Rust inhibitive oils were of no value. Rust inhibitive greases of the paral-ketone type were moderately successful on silver plated metals only. Strippable lacquer films protected steel and silver well but were of little or no value on copper base alloys and zinc.
