CONDUCTIVE PRECOATED ALUMINUM ALLOY PLATE EXCELLENT IN SLIDING PROPERTIES

摘要

PPROBLEM TO BE SOLVED: To provide a conductive precoated aluminum alloy plate excellent in the adhesion of a coating film and moldability and having excellent conductivity and sliding properties. PSOLUTION: The conductive precoated aluminum alloy plate comprises the chemical forming film 3 formed on a surface of a substrate 2 and the conductive layer 4 formed thereon. The conductive layer 4 comprises a base coating film 40, one or two kinds of a scaly Ni filler 45 with a thickness of 0.2-5 m and a long diameter of 1-100 m or a spherical Ni filler 45 with a diameter of 0.3-20 m and inner wax. The total weight of the conductive layer 4 after drying is 0.3-5 g/mSP2/SPand the content of the Ni filler 45 is 3-70 pts.wt. and the content of the inner wax is 0.01-10 pts.wt. with respect to 100 pts.wt. of the total weight of the conductive layer 4 after drying. The number of the Ni fillers on the surface of the coating film is greater than 900 and 10,000 or less per mmSP2/SPby observation with a scanning electronic microscope. The surface average roughness Ra of the conductive layer 4 is 0.1-0.9 m and the coefficient of friction thereof is 0.03-0.5. PCOPYRIGHT: (C)2009,JPO&INPIT
