Abstract
Methods of pre-conditioning and lubricating the rubbing surfaces of steel substrates are provided. The methods include a pre-conditioning step in which a hydrocarbon fluid having cycloalkane carboxylic acid additives dispersed therein is used to form a tribofilm on a rubbing surface of a device, following by replacing the pre-conditioning lubricant with a cycloalkane-carboxylic acid-free hydrocarbon lubricant for the regular operation of the device. The tribofilm formed during the pre-conditioning step provides long-term friction and wear reduction at the rubbing surfaces, even after it is replaced, and allows for the subsequent operation of the device without the need to change the composition of the regularly used lubricant.
