Abstract
A wear resistant coating is applied to the thrust surfaces and bore surfaces of a connecting rod. The wear resistant coating includes a polymer matrix, such as polyamide imide (PAI), solid lubricant, and hard particles including FeO. The wear resistant coating is typically applied by spraying or rolling. The wear resistant coating adheres well to metal and provides lubrication. Thus, the wear resistant coating can reliably reduce wear, scuff, and seizure along the surfaces of the connecting rod as the piston reciprocates and crank shaft rotates during operation of the internal combustion engine. The likelihood of engine contamination caused by metal shavings from wear of the connecting rod is reduced, and the life of the connecting rod and engine is increased.
