Abstract:

A feasibility study was conducted to determine whether a technique could be established for sputtering a coating in the bore. A movable electrode technique was developed which appeared to be practical. In this technique the target was placed inside the bore and was moved along the length of the barrel while the sputtering action was occurring. Under controlled sputtering parameters gas pressure, target potential, target current and target movement, this technique has a projected capability of the deposition of a uniform thickness of coating. Several other sputtering techniques were investigated and were generally unsuccessful in the accomplishment of a working procedure.
