Title:
錫めっき材およびその製造方法
Document Type and Number:
Japanese Patent JP4749746
Kind Code:
B2
Abstract:
A tin-plated product formed by electroplating a substrate in a tin plating solution, which contains carbon particles and an aromatic carbonyl compound, to form a coating of a composite material, which contains the carbon particles in a tin layer, on the substrate has a coefficient of friction which is not greater than 0.18, preferably not greater than 0.13, with respect to the same kind of another tin-plated product, and has a glossiness of not less than 0.29 and a contact resistance of not greater than 1.0 m©. The coating has a thickness of 0.5 to 10 micrometers, and the content of carbon in the coating is in the range of from 0.1 % by weight to 1.5 % by weight. Separate protrusions containing the carbon particles are formed on the surface of the coating. The orientation plane of a tin matrix of the coating is (101) plane.
