Extrusion component having lubricious coating and method of extruding abrasive material

Abstract

A method of increasing the lubricity of an extrusion component, the method comprising: functionalizing a surface of a wall of an extrusion body with PDA material to form a PDA treated surface; coating the PDA treated surface with a lubricious material; and heat treating the wall of the extrusion body for a time and a temperature sufficient to cause the lubricious material to adhere to the PDA material, and for the PDA material to adhere to the wall; wherein the surface of the wall is optionally oxidized prior to the functionalizing. Also an extrusion component comprising: an extrusion body comprising an inlet face and an outlet face, the body comprising a base structure comprising an internal wall defining at least a portion of an extrusion pathway from the inlet face to the outlet face, wherein at least part of the internal wall comprises a lubricious coating that defines at least part of the extrusion pathway.
