Solid lubricant basics

Solid lubricants generally separate surfaces better than liquid lubricants, but they are eventually expelled from a contact.  Solid lubricants are back into the contact to repair the lubricant film.

To slow the removal of lubricant from a contact two approaches can be taken.

• The first option is to add an adhesive such as epoxy resin which helps the lubricant adhere to the surface.
• The second option is to keep replenishing the lubricant on the surface.  This can often be accomplished through a chemical reaction between the surface and a surrounding fluid.
