Abstract
Thin-film coatings on the order of nanometers in thickness are particularly susceptible to atmospheric contamination which may negatively impact both their composition and performance. Testing in a high-vacuum environment is desirable to get an accurate assessment of performance and may also be used to quantify the effects of process behavior on a coating performance. In later chapters, we will explore how deposition process variables such as pressure and voltage influence the performance of a solid silver lubricant applied to ball bearings that operate in high vacuum. Effects of these process variables on the lubricating film composition will be discussed as well.
