Wear and contact fatigue properties of a novel lubricant additive
Wear and contact fatigue properties of a novel lubricant additive
Lubrication is generally thought to take place in wet conditions, forming a protective tribofilm as a result of metal-to-metal contact and pressure. A novel lubricant additive (Lofrix Dry, LD) is presented here that shows improved wear resistance, strong tribofilm adhesion to steel surfaces, and a reduced coefficient of friction. LD contains a mix of alkanes and chlorinated paraffins in a range of molecular sizes, and it can be applied as a dry coating and even when surfaces are not in contact. The dry-condition and low-temperature application makes LD a unique choice for simplifying the design of components in mechanical contact. This paper presents an outline of future work to identify the nature, characteristics, and repeatability of Lofrix tribofilm.

Abstract
Lubrication is generally thought to take place in wet conditions, forming a protective tribofilm as a result of metal-to-metal contact and pressure. A novel lubricant additive (Lofrix Dry, LD) is presented here that shows improved wear resistance, strong tribofilm adhesion to steel surfaces, and a reduced coefficient of friction. LD contains a mix of alkanes and chlorinated paraffins in a range of molecular sizes, and it can be applied as a dry coating and even when surfaces are not in contact. The dry-condition and low-temperature application makes LD a unique choice for simplifying the design of components in mechanical contact. This paper presents an outline of future work to identify the nature, characteristics, and repeatability of Lofrix tribofilm.
