Method for treating metal surface, rotary shaft for refrigerant compressor treated by the method, vane for refrigerant compressor treated by the method, and refrigerant compressor using the same
摘要：
The present invention is to provide a refrigerant compressor comprising a compressing element driven by a rotary shaft, for compressing and discharging a sucked HFC type refrigerant or refrigerant mainly comprising the HFC type refrigerant by the compressing element, where a rotary shaft applied with the plasma sulphonitriding treatment on the surface is used as the rotary shaft. Or a vane applied with the plasma sulphonitriding treatment on the surface of a vane made of a steel equivalent to a high speed tool steel vane or a steel equivalent to a stainless steel is used. Accordingly, a refrigerant compressor comprising a rotary shaft or a vane having a low friction coefficient in a sliding portion on the surface of the rotary shaft or the vane and a high wear resistance can be provided even in the case an ester type refrigerator oil or an ether type refrigerator oil is used as the refrigerator oil and an HFC type refrigerant is used.
摘要（中）：

本发明提供一种制冷剂压缩机，其包括由旋转轴驱动的压缩元件，用于通过压缩元件压缩并排出主要包含HFC型制冷剂的HFC型制冷剂或制冷剂，其中施加有等离子体磺化氮 表面处理用作旋转轴。 或者使用等离子体磺化氮化处理在由等效于高速工具钢叶片或相当于不锈钢的钢制成的叶片的表面上施加的叶片。 因此，即使在酯型制冷机油或其制造方法中，也可以提供包括在旋转轴或叶片的表面上的滑动部分中具有低摩擦系数的旋转轴或叶片的高耐磨性的制冷剂压缩机， 使用醚型冷冻机油作为冷冻机油，使用HFC型制冷剂。
