A piston has a piston main body including an aluminum alloy, and a covering layer formed on the outer surface of the piston main body, and the covering layer has a first plating layer including an iron-phosphorous alloy, and a second plating layer including a nickel-phosphorous alloy formed on the first plating layer.

Piston for vehicle disc brake and manufacturing method thereof

A radiation member includes a base material; and a composite plating layer, formed on the base material, that includes a metal layer and two or more kinds of carbon materials, having different diameters from each other, dispersed in the metal layer such that to be provided with a plurality of protruding portions, each of the protruding portions being composed by a part of each of the carbon materials that are protruded from a surface of the metal layer.

Radiation member

In one embodiment, there is provided a composite plating liquid. The composite plating liquid includes: a plating metal salt; a sulfate of at least one element selected from alkali metals and alkaline earth metals; boric acid; a carbon nanotube; and a dispersant. Also, there is provided a plating method of plating a member using the composite plating liquid, and a composite plating film formed by the plating method.

Composite plating liquid

A composite plating layer contains carbon nanofibers. A composite plating solution contains a Watts bath composed mainly of nickel sulfate and nickel chloride, a brightening agent, a surface active agent and carbon nanofibers. Polyacrylic acid is used as the surface active agent.
