Novel Oil-Free Solid Lubricant
Researchers at Purdue University have developed a novel graphene-zinc oxide based composite film for use as a solid-state lubricant for friction and wear reduction under extreme load conditions. Using a ball-on-disk tribometer for testing, the composite film maintained its lubricating effects under extreme operating conditions. Furthermore, it reduces friction and wear between surfaces than oil-based lubricants. Because the lubricant is not oil-based, it allows for more effective utilization in high temperature or extreme low pressure applications. The durability and resilience of this adhesive coating suggest exceptional potential as a dry lubricant for high load-bearing applications.
