SST Cold Spray Technology Restores High-Value Precision Gauging Fixtures

Abstract

Supersonic spray technology (SST) cold spray enables metal consolidation that can dimensionally restore precision gauges and fixtures made from heat-sensitive aluminum alloys. This case study describes how a manufacturer of high-precision aluminum gauging fixtures used SST cold spray technology to salvage a number of high-value fixtures that were either incorrectly machined or simply worn beyond their useful life.
