Abstract

A component is provided including a body formed at least partially from a composite material. At least a portion of the composite material is covered by a plating. The plating includes a layer of electroless copper, a layer of electrolytic copper, a layer of nickel strike, and a finishing layer.

First claim

The invention claimed is:

1. An engine-mounted actuator for an aircraft comprising,
a body formed at least partially from a thermal plastic material, a portion of the thermal plastic material being covered by a plating, the plating including a layer of electroless copper, a layer of electrolytic copper, a layer of nickel strike, and a finishing layer, the body comprising one of a housing, an endcap or a piston rod of the engine-mounted actuator, the layer of nickel strike having a thickness between 0.00005 inches and 0.0001 inches;
wherein the engine-mounted actuator is a hydraulic linear actuator of a thrust reverser actuation system.

2. The engine-mounted actuator according to claim 1 , wherein the layer of electroless copper is arranged directly in contact with an exterior surface of the thermal plastic material.

3. The engine-mounted actuator according to claim 2 , wherein the layer of electrolytic copper is positioned adjacent the layer of electroless copper.

4. The engine-mounted actuator according to claim 3 , wherein the layer of nickel strike is positioned between the layer of electrolytic copper and the finishing layer.

5. The engine-mounted actuator according to claim 1 , wherein the finishing layer includes an additive to enhance the wear resistance of the finishing layer.
