Abstract: Disclosed are methods of enhancing resistance to erosion, corrosion, wear and tear, and fatigue in high-pressure pumps. One method includes providing a fluid end that comprises a body defining a pressure chamber in fluid communication with a plunger bore having a plunger reciprocably disposed therein, a suction valve pocket defined in the body and having inlet valve assembly arranged therein that includes a suction valve and a suction valve seat, and a discharge valve pocket defined in the body and having a discharge valve assembly arranged therein that includes a discharge valve and a discharge valve seat, and applying a wear-resistant substance directly to a surface of at least one of the pressure chamber, the plunger, the suction valve pocket, the suction valve, the suction valve seat, the discharge valve, and the discharge seat.
