ABOUT

PURPOSE:

To evaluate the impact on electrical stability of the contact system when exposed to any environment which may generate thermal/moisture type failure mechanisms such as:

1. Fretting corrosion due to wear resulting from micromotion. Thermal cycling induces micromotion between contacting surfaces and humidity accelerates the oxidation process.
   
   
2. Fretting corrosion of non-noble finish systems.
   
   
3. Oxidation of wear debris which may have become entrapped between the contacting surfaces due to induced micromotion.
   
   
4. Oxidation of particulates which may have been deposited on or entrapped between the contacting surfaces from the surrounding atmosphere via the wet oxidation process, detect loss of electrical stability due to particulates which may be deposited on contacting surfaces, wear which may expose base metal or underplates of contacting surfaces, and oxidation on non-noble finish systems.
