Abstract

PURPOSE: To form innumerable wear-resistant fine protrusions on the surface and thereby to improve th bonding strength of the surface, by subjecting the surface of a fluorocarbon resin molding to a sputter-etching treatment and then to a chemical treatment with a solution contg. an alkali metal.
CONSTITUTION: The surface of a fluorocarbon resin molding obtained by molding a fluorocarbon resin such as polytetrafluoroethylene into a desired shape is subjected to a sputter-etching treatment under conditions including a pressure of atmospher of 0.0005W0.5 Torr to form innumerable fine protrusions on the surface. Then the sputter-etched surface is subjectd to a chemical treatment with solution contg. an alkali metal such as a solution of metallic sodium in liquid ammonia or a solution of metallic sodium/naphthalene complex in tetrahydrofuran. Thus, the wear resistance of fine protrusions is improved, and it is possible to maintain the fine protrusions in the form as they formed until the surface is bonded to a different material.
