ABSTRACT:
A method of manufacturing a plunger for a downhole reciprocating oil well pump for use in sandy environments including the step of machining a metal plunger to the required base configuration with an external cylindrical pump surface having a diameter of about 0.025 inches less than the design diameter, grit blasting the plunger cylindrical pump surface to achieve a textured surface thereon, heating the plunger, flame spraying a thin layer of ceramic composite on the plunger cylindrical pump surface, repeating the flame spraying steps sequentially until the diameter of the cylindrical pump surface having the ceramic composite thereon is about 0.015 to 0.020 inches above the design diameter, cooling the plunger and grinding the ceramic covered plunger pump surface to the design diameter.
