摘要： PURPOSE:To prevent leakage of gas and abnormal wear of apex seals, by embedding boron nitride in pores of porous chromium plating at a specific area ratio. CONSTITUTION:Porous chromium plating 3 is applied over the trochoidal inner surface of a rotor housing 1 and boron nitride 5 is embedded in pores 4. Porosity of the pores 4 in the surface of the porous chromium plating 3 is 10-60%. In case that the pores 4 are of the pin-point type, the diameter l at the opening of the pores 4 is about 1-2mum. In case that the pores 4 are of the channel type, on the other hand, the width of the groove at its open end is selected to be 2mum or less. The depth is preferably 8-12mum in either case. The boron nitride 5 is made of fine particles having diameters of about 0.1-0.2mum and the boron nitride 5 embedded in the surface of the porous chromium plating 3 in 5-50% by the area ratio. Since boron nitride is not subjected to oxidation even under an oxidizing atmosphere if the temperature is lower than about 900 deg.C, stable self- lubricating performance can be obtained even under high temperatures.
摘要翻译：目的：为了防止气体泄漏和顶点密封件异常磨损，以氮化硼以特定面积比包埋多孔镀铬孔。构成：多孔镀铬3施加在转子壳体1的摆线内表面上，氮化硼5嵌入孔4中。多孔铬镀层3的表面孔4的孔隙率为10-60％。在孔4为针尖型的情况下，孔4的开口处的直径l为约1-2μm。另一方面，在孔4为通道型的情况下，其开口端的槽的宽度选择为2μm以下。在任一情况下，深度优选为8-12μm。氮化硼5由具有约0.1-0.2μm的直径的细颗粒和多孔镀铬3的表面中的氮化硼5以面积比5-50％制成。如果温度低于约900℃，氮化硼即使在氧化气氛下也不会发生氧化，即使在高温下也能获得稳定的自润滑性能。
