The wear and lubrication performance of liquid-solid self-lubricated coatings

It was found that the coatings provided a good lubrication performance as long as the matrix material was not remelted after spraying using capsules with thin wall. For the non-remelted coatings, the coefficient of friction remained below 0.2 and the material loss varied depending on the normal load and on the spraying parameters. The coatings obtained with thick wall capsules resisted better the thermal input, but the lower amount of lubricant was insufficient to keep low friction under certain loading conditions.
