Modified Ionic Liquid-Based High-Performance Lubricants for Robotic Operations

NASA needs an advanced lubrication solution for its future robotic systems and planetary surface assets. The required lubrication technology must offer low-temperature performance while minimizing wear in these robotic systems and reducing the maintenance needed to keep them running. In this Phase II project, InnoSense LLC (ISL) proposes to meet NASA's need by further-engineering of its IonoGlide?liquid-based lubricants and validating its performance through testing by third party. IonoGlide lubricants offer low-temperature performance with limited off-gassing and high decomposition temperatures. ISL's approach is to introduce proprietary additives to the ionic liquid matrix to impart thermal stability and enhance lubricity. This depresses the apparent freezing point while maintaining high decomposition temperatures. Through electrostatic interactions, the proprietary additive and ionic liquid form an order. With near metallic surfaces, this quasi-ordering contribute to improved lubricity. Phase I testing shows that ISL's lubricant outperforms top commercially available lubricants. ISL will work with a major NASA contractor to test lubrication efficiency under simulated field conditions. IonoGlide lubricants are envisioned for use primarily in metallic ball-bearing conditions at low pressures.
