Ionic liquids(ILs)have been used effectively in many applications for reducing problems related to friction and wear.In this work,the potential of ILs as an anti-wear and extreme pressure lubricant additive for high l...
Lubricants have played important roles in friction and wear reduction and increasing efficiency of mechanical systems.To optimize tribological performance,chemical reactions between a lubricant and a substrate must be...
