Abstract
A piston testing apparatus is provided including a housing having an inner wall and defining a cavity therethrough; a piston disposed in the housing cavity and having a polymer coating deposited thereon, wherein the polymer coating of the piston contacts the housing inner wall; a connecting rod coupled to the piston; and an actuator coupled to the connecting rod and configured to provide a reciprocating movement of the piston through the cavity. An injection plate for the piston testing apparatus and a method for challenging an adhesion of the polymer coating to the piston are also described.
