Abstract

PURPOSE:To improve wear resisting performance and seizure resisting performance by providing a coating layer of arbitrarily compound-plating ceramics of teflon while forming a cylinder block, both side blocks, rotor and vanes of plastic or carbon material reinforced by mixing metal powder in it. CONSTITUTION:A rotor 4, provided with a drive shaft 2 in the center and formed with vane grooves 3, is inserted, so as to come into contact in the vicinity of both upper and lower parts of inner surface of a cylinder block 1, to provide two action spaces 5. Vanes 6 are slidably inserted into the vane grooves 3. Further, a front side block and a rear side block are provided in both sides of the cylinder block 1. Here, a plastic or carbon material, mixing metal powder reinforced, is used as a forming material of the cylinder block 1, rotor 4 and the vanes 6. A coating layer C, arbitrarily applying compound plating of ceramics or teflon to a single or compound plating-possible metal, is provided in sliding surfaces or the like between the front/rear side blocks and the rotor 4 and the vanes 6.

(Problem to be solved by the invention) However, in this type of compressor, it is possible to reduce the weight by using aluminum-based light metal, and at the same time, it is possible to improve seizure resistance and wear resistance. In (1), the anodic coating is of the same type as the mating material and is insufficient in terms of durability such as sliding properties and seizure resistance. or,
In the above (2), Hv=300 in the case of a plating layer made of ceramics as a dispersion material, or SIC, for example.
0~3500, Hv・2800~38 in case of TIC
00, Hv・2400~2800 in case of SI3N4
Because it is extremely hard, the workability of polishing after plating becomes poor, the grinding time increases, and the life of the whetstone becomes extremely short, resulting in low productivity.

In addition, there is a technology that uses iron plating, but the dimensional accuracy of the plating film thickness is poor, and finishing processing is required after plating, resulting in high costs.The adhesion to the aluminum material deteriorates due to repeated thermal shocks, resulting in poor durability. There is also the above problem.
