The present invention provides a contact member that strikes a balance between low electrical resistance and sliding durability under the condition of load as low as about 0.1 N. A contact member of the invention has a metal base and a coating disposed on at least part of the metal base. The coating contains fluorinated oil having a polar group, and metal particles surface-treated with a fluorine-based compound having a polar group.

A cold spray lubricant for forming a coating includes an alloy feedstock consisting of a metal powder such as copper or nickel, and a solid lubricant, such as tungsten disulfide (WS.sub.2) powder or molybdenum disulfide (MoS.sub.2).

The present invention is a grease pod to simplify and enhance the application of grease to ball hitches used in towing trailers and fifth wheel hitches. The grease pod includes a multi-layered body adapted to fit snugly over the hitch. The pod includes an inner layer and an outer layer, both made from a film, heat-sealed together to form a secure and pressure sensitive enclosure. A premeasured quantity of grease is included in the enclosure and can be available in various formulations such as marine grade grease, lithium, and graphite powder. Upon applying pressure when the trailer coupler or fifth wheel coupling is engaged, the grease pod bursts and releases the grease to evenly coat and lubricate the hitch. The method of use involves placing the pod on the ball hitch and lowering the trailer coupler or engaging the fifth wheel to apply pressure, ensuring precise lubrication.

A coating to reduce friction, the coating including an amorphous metal, and a solid lubricant. The solid lubricant may be dispersed with the amorphous metal throughout the coating, or the solid lubricant may form a layer on top of the amorphous metal. The coating may be applied to various components such as aircraft components, gas turbine engine components, etc., to reduce friction.

A sliding material includes a resin, first particles disposed in the resin and composed of an inorganic material, and second particles disposed in the resin and composed of an inorganic material whose Vickers hardness is higher than a Vickers hardness of the first particles. When a value obtained by dividing a Vickers hardness of the second particles by the Vickers hardness of the first particles is defined as a hardness ratio and when a value obtained by dividing a contained amount of the first particles with respect to the resin by a contained amount of the second particles with respect to the resin is defined as a content ratio, a value obtained by dividing the hardness ratio by the content ratio is greater than or equal to 0.3 and less than or equal to 2.8.
