2. Description of the Related Art Lubricating oil has been added to sliding parts in a compressor by adding lubricating oil to Freon gas as a refrigerant. With the recent substitution of CFCs, the lack of lubricity of CFC substitutes has increased seizure between the sliding surfaces, causing a serious problem that the product life of the compressor is significantly shorter than before. For this reason, attempts have been made to prevent seizure by using a method of substituting a lubricating oil to be added to a refrigerant or a method of coating a sliding member with a single-layered dry lubricating film to improve the product life.

The dry lubricating coating containing the binder resin has a relatively high hardness and is excellent in durability because the solid lubricant is held on the sliding surface for a long period of time. However, in order to exhibit these performances, it is necessary to transfer solid lubricant fine particles to the sliding surface of the mating member and to prevent adhesion between the binder resin and the mating metal surface, so-called initial adaptation. If this initial break-in is not successful, adhesion between the resin and the mating metal surface occurs, leading to peeling of the coating layer, generation of large wear powder, rapid increase in film wear due to polishing of the wear powder, and furthermore, the occurrence of seizure. .

This initial break-in is a very stochastic phenomenon in which the solid lubricant in the coating is transferred to the mating material, and the transferred portion and the binder resin have slippage. If the ratio of the solid lubricant to the resin is increased, the probability of transfer increases, so that the initial adaptation becomes better. However, since the resin ratio decreases, the holding force of the solid lubricant on the sliding surface decreases, and the durability decreases. Conversely, if the resin ratio is more than a certain
Since the adhesion between the resins increases, abnormal wear is apt to occur, and the life is extremely shortened. Due to these problems, the durability and coefficient of friction of the dry lubricating coating have some limits.

On the other hand, the lubricating film obtained by the blast coating method shows a very low coefficient of friction from the beginning of sliding because the crystal orientation of the molybdenum disulfide on the sliding surface is completed at the time of film formation.

In the sliding device of the present invention, a dry lubricating film containing a binder is formed on one of the pair of members, and a film having a crystal orientation of, for example, about 1 μm is formed on the other member. By forming a thick solid lubricant film such as molybdenum disulfide, adhesion between the resin and the mating member in the initial stage of friction is prevented. Since a slight adhesion of the binder cannot be prevented by ordinary initial adaptation, the specific wear rate exceeds a certain level, but in the case of the combination of the lubricating coating of the present invention, the adhesion of the resin to the mating member is completely prevented. To prevent this, the specific wear rate is reduced. Therefore, the time until the dry lubricating coating is completely worn is greatly increased, and the lubrication life is extremely prolonged.

In this embodiment, a rotary vane type compressor is described in which a dry film lubricant is applied to the vane side and a solid lubricant film is applied to the side plate. The same effect can be obtained by applying a lubricant film and applying a dry film lubricant to the side plate. Similar effects can be obtained by applying a similar coating to the rotor and the side plate with respect to the sliding between the rotor and the side plate. Also, it is clear that the same effect can be obtained by applying a coating to a member having a sliding surface in a compressor of an air conditioner such as a swash plate type reciprocating piston type compressor or a scroll type compressor.
