JPS6281265A - Sliding member - Google Patents

Abstract

PURPOSE:To obtain a sliding member having high mechanical strength, lightweightness and excellent sliding characteristic by plating metal to part or the whole of a molding manufactured of a composite carbon metallic material and soldering the plated body and metallic molding. CONSTITUTION:A prescribed shape is cut out of the composite carbon metallic material consisting of silicon carbide, carbon and aluminum or aluminum alloy or carbon and copper or copper alloy, etc. in the manufacture of a vane for an inverter rotary air conditioner. Part or the entire surface thereof is subjected to metal plating such as chrome plating or nickel plating. On the other hand, solder is stuck to one surface of the metallic molding having the prescribed shape and a flux is coated on the joint surface of the above-mentioned plated body. The plated body is superposed on the solder surface and both surfaces are heated, pressurized, then cooled. The composite vane member having the high mechanical strength, lightweightness and excellent sliding characteristic is thus obtd. at a low cost.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a sliding member.

[Conventional technology]

Conventionally, for example, the vanes of inverter rotary air conditioners were made of steel.

Although steel has high mechanical strength, it is very heavy (density 7°8)
Moreover, the sliding properties were not fully satisfactory, and therefore the service life was short.

Recently, there has been a demand for equipment that requires sliding to be lightweight and have excellent sliding properties, and in response to this demand, carbon-metal composite materials have come to be used.

However, carbon-metal composites are light (the density is about 1/4 that of iron).
) It has excellent sliding properties, but has the drawbacks of being very expensive and having low mechanical strength.

[Problem that the invention seeks to solve]

It is an object of the present invention to provide a sliding member that is inexpensive, has high mechanical strength, and has excellent sliding characteristics.

[Means for solving problems]

As a result of the inventors' research to solve the above problems,
The present invention was developed based on the knowledge that a structure obtained by applying metal plating to a carbon-metal composite material and soldering it to metal using the plating layer has high mechanical strength and excellent sliding properties. completed.

〔composition〕

The gist of the present invention is to form a molded body made of a carbon-metal composite material as a vane tip, a part of which is plated with metal, and a metal vane body is soldered with the resulting plated body interposed therebetween. It is a moving member.

[Effect]

Carbon-metal composites include silicon carbide, carbon and aluminum or aluminum alloys, carbon and copper or copper alloys, and the like.

Examples of metal plating include chromium plating, nickel plating, copper plating, etc., and either electroplating or electroless plating may be used.

〔effect〕

The sliding member of the present invention has a sliding part made of carbon-metal composite material and other parts made of metal material, so it has high mechanical strength, excellent sliding properties, and reduced weight. Furthermore, since only a small amount of expensive carbon-metal composite material is required, the manufacturing cost is extremely low.

Production example An example of manufacturing a sliding member according to an embodiment of the present invention is shown.

A carbon-metal composite is cut into a predetermined shape, and then metal plating is applied to one side of the carbon-metal composite by electroplating or electroless plating.

Next, flux (for example, a flux mainly composed of ammonium chloride) is applied to the plated surface, and soldering is performed.

On the other hand, solder is applied to one side of a metal molded body of a predetermined shape to be joined to the carbon metal composite, the solder surface of the metal body and the solder surface of the carbon metal composite are aligned, and the solder components are fused by heating and pressurizing. By cooling it, the sliding member of the present invention with excellent sliding properties and high mechanical strength can be obtained.
