1. A fluid handling component comprising:
a component body including a surface at least partially defining an internal passage positioned to receive fluid flow therethrough; and
a coating at least partially covering the surface of the fluid handling component body to enhance wear resistance of the fluid handling component body, such that the fluid handling component exhibits a wear resistance comparison factor indicative of an increased resistance to wear greater than about 2, the wear resistance comparison factor being indicative of a first amount of time during which a portion of the coating wears to a first depth divided by a second amount of time during which a corresponding portion of a comparable fluid handling component body without the coating wears to a second depth equal to the first depth, and the coating comprising:
a primer applied to the surface of the fluid handling component body; and
a coating composition at least partially coating the primer, the coating composition comprising trifunctional silane, silanol fluid, titanium dioxide, and filler, and the coating composition being positioned to chemically bond with the primer.
