A coated metal pipe for use as an automotive fluid transport tube is provided comprising: a single or double walled tubing formed into a circular cross-sectional profile; at least one intermediate layer primer layer applied over said tubing: and an outer layer comprising a polyamide incorporating an immiscible additive. The immiscible additive is selected from Ultra High Molecular Weight (UHMW) silicones, UHMW polyethylene (UHMW-PE), polytetrafluoroethylene (PTFE) and mixtures thereof.

Method and apparatus are provided for electroplating a surface area of an internal wall defining a cooling cavity present in a gas turbine engine component.

An article that includes a structured substrate having a macro-porous structure that defines a plurality of pores, and a metallic nano-crystalline coating on at least a portion of the structured substrate, where the metallic nano-crystalline coating defines an average grain size less than about 20 nanometers.

An electro plating device includes a pipe inside seal mechanism which occludes an inner channel of a steel pipe, a tubular insoluble electrode which is disposed in a pipe end so as to be opposite to a female screw, a plating solution feed mechanism which includes a plurality of nozzles which extend radially with a pipe axis of the steel pipe as a center, and a pipe end seal mechanism which accommodates the nozzles thereinside and is mounted to the pipe end, when viewed in the pipe axial direction, a tip of each of the nozzles is positioned between the female screw and the insoluble electrode, and each of the nozzles injects the plating solution toward a direction which intersects an extension direction of the nozzle, the direction being a rotational direction of a clockwise direction or a counterclockwise direction in which the pipe axis is the center.

In an anodizing method of aluminum, a tubular object made of aluminum or aluminum alloy is located between a pair of cathodes in an electrolysis solution, and a subsidiary cathode is inserted into the tubular object. The tubular object is anodized in the electrolysis solution to form an anodic oxide coating on an inner surface of the tubular object and on an outer surface of the tubular object. Accordingly, the anodic oxide coating can be formed easily not only on the outer surface of the tubular object but also on the inner surface of the tubular object. Therefore, a thickness difference of the anodic oxide coating between on the outer surface of the tubular object and on the inner surface of the tubular object can be reduced.

A plated tubular lattice structure is described. The plated tubular lattice structure may comprise a backbone structure which may include a plurality of axial posts and a plurality of pyramidal structures extending laterally from the axial posts and connecting the axial posts at nodes. The plated tubular lattice structure may further comprise a metal plating layer plated on an outer surface of the backbone structure.
