(57) [Problem] To form a film having excellent wear resistance by forming a chemically adsorbed film by adding a cross-linking agent of the same type as the chemical adsorbent to the chemically adsorbed liquid to cross-link the adsorbed molecules. provide. SOLUTION: As a chemical adsorbent, for example, CF 3 (C 5% by weight of F 2 ) 7 (CH 2 ) 2 SiCl 3 , 3% by weight of, for example, hexachlorodisiloxane as a cross-linking agent, and 92% of cyclohexane (bp. A liquid is prepared, applied to an aluminum substrate 11 in a dry atmosphere, and the solvent is removed by evaporation. The molecules are crosslinked in a state where the molecules are entangled with each other, and further form a polymer film 12 covalently bonded to the substrate surface. |
