The glow discharge energizing favorably modifies and |
|
controls the coating/substrate adherence and the |
|
nucleation and growth sequence of ion plated gold films. |
|
As a result the adherence, coherence, internal stresses, |
|
and morphology of the films are significantly improved. |
|
Gold ion plated films because of their graded |
|
coating/substrate interface and fine uniform densely |
|
packed microstructure not only improve the tribological |
|
properties but also induce a surface strengthening effect |
|
which improves the mechanical properties such as yield, |
|
tensile, and fatigue strength. Consequently significant |
|
improvements in the tribological performance of ion |
|
plated gold films as compared to vapor deposited gold |
|
films are shown in terms of decreased friction/wear and |
|
prolonged endurance life. |
