Corrosion inhibiting lubricants for separable connectors

Microcrystalline wax by itself or in combination with polyphenyl ether inhibits corrosion, increases contact wear life, and lasts for reasonable times at higher operational temperatures. All other lubricant combinations evaluated either did not inhibit corrosion and improve wear performance or have sufficient longevity for practical contact applications. In addition to evaporative loss, lubricant mobility and absorption into the substrate cause depletion in the contact region. The wax lubricant cannot be exposed to temperatures above the melting point of the wax during processing, shipping, storage, or use. The wax becomes more mobile and reduces its effectiveness as a corrosion inhibiting layer.
