Abstract : This report describes the process used to fabricate thin wall cylindrical shells by sputtering. The shells are grown on both sacrificial aluminum and reuseable stainless steel mandrels. The post deposition process used to remove the shells from the mandrels is described. The effect of deposition conditions and post deposition treatment on crystallographic structure is presented. Comparisons of sputtered shells are made with conventionally machined ones as pertains to dimensional uniformity and performance. Test results of sputtered thin wall cylindrical shells used as pressure sensing elements are given.
