Abstract: (submitter)
The intent of this project is to compare the particle generation and gall prevention characteristics of stainless steel, silver coated, and TiN coated fasteners. To achieve this goal, the following steps were taken: • A testing stand was designed to be compatible with cleanroom requirements. • Data acquisition programs and equipment were obtained and implemented. • Particle count data was collected during the assembly and disassembly of conflat vacuum flanges. • Observations of galling and particle generation phenomena were made. • A Student T-test was applied to the collected particle data to determine the statistical significance of the collected data. • Samples were placed under a Scanning Electron Microscope to examine particle generation phenomena.
