METHOD OF FORMING CONDUCTIVE ROUGH SURFACE AND FORMING MATERIAL FOR CONDUCTIVE ROUGH SURFACE

摘要

PROBLEM TO BE SOLVED: To provide an anti-corrosion surface treatment technique in which adhesiveness and sacrificial anti-corrosion action are highly combined. SOLUTION: A conductive rough surface coated film comprising a rough surface forming material is formed on a metal material 1 by using the rough surface forming material formed by dispersing 90-700 vol.% of conductive particles 2a with a particle size of not larger than 500μm to resin, with a viscosity of 400-1200mPa s(±200mPa s)measured in conformity to JIS K 6833, and with a surface drying (ballotini method) of 2-30 minutes measured in conformity to JIS K 5600-3-2, and by coating it by spraying onto the metal material 1 in conditions of a spraying pressure of 0.3-1.0 MPa and a spraying distance of 50-400mm.
