冷蔵庫やエアコン等のロータリーコンプレッサーに用い
られるベーン材としては、高速原調、特殊鋳鉄、鉄系粉
末焼結合金等の鉄系材料が従来用いられている。As vane materials used in rotary compressors such as refrigerators and air conditioners, iron-based materials such as high-speed originals, special cast iron, and iron-based powder sintered alloys have been conventionally used.

返している。FIG. 1 is a cross-sectional view schematically showing the structure of a rolling piston compressor, in which a piston 4 moves eccentrically around a shaft 5 in a cylinder 3, thereby sucking, compressing, and discharging refrigerant gas. It is done. At this time, the vane 6 serves as a gas sealing material and receives sliding movement from both the cylinder 3 and the piston 4. FIG. 2 is a cross-sectional view schematically showing the structure of a vane rotary compressor, in which a rotor 8 with vanes 6 rotates in an elliptical cylinder 9, and the rooms divided by each vane 6 are The suction-compression-discharge operation is repeated.

た材質と摺動する際の耐摩耗性、耐焼付性に借れでいる
事が要求されている。Generally, in these rotary compressors, the cylinder and piston are made of different materials (for example, in the case of a rolling piston compressor as shown in Figure 1, cylinder 3 is made of soft eutectic graphite cast iron, etc., and piston 4 is made of heat-treated material). (In many cases, MoNiCr cast iron, etc., which has increased strength is used), therefore, the vane material is also required to have good wear resistance and seizure resistance when sliding with these different materials. There is.

れている。Furthermore, regarding the clearance of the sliding surface, for example, the first
In the case of a rolling piston compressor as shown in the diagram,
The cylinder 3 and the vane 6 are fitted so that the clearance therebetween is on the order of μm, and the coefficient of thermal expansion of the vane 6 is required to be close to that of the cylinder 3.

係数の点からもＡｔ合金製ベーンが用いられている。In addition, in the vane rotary type compressor as shown in Fig. 2, since the vanes 6 formed from the birch mentioned above form part of the rotating body, the input reduction effect by reducing the weight of the vanes 6 is large, and the weight of the vane material can be reduced. It is strongly required. In the case of automobile air conditioners, weight reduction is required, so the housing and compressor rotor 8 are made of A1 alloy. Vanes made of At alloy are also used.

れていなかった。However, although conventionally used iron-based materials such as high-speed steel have excellent wear resistance and a coefficient of thermal expansion close to that of the other material, improvements in weight cannot be achieved. It was needed. On the other hand, although Al-based materials are superior in terms of weight reduction, their wear resistance is significantly inferior to iron-based materials.
Furthermore, since the coefficient of thermal expansion is quite different from that of cylinders and pistons, it has not been put into practical use except for the above-mentioned automobile air conditioners.
