Abstract
A downhole tool or component, such as a hydraulic fracturing ball, may have a base body having an outer surface. The outer surface of the base body may have a lapped coating thereon. The downhole tool or component may be made by lapping the outer surface of the base body with a lapping slurry. The downhole tool or component may be used in downhole applications, such as hydraulic fracturing, and may resist degradation upon exposure to fluids, such as production fluids.
