    • PURPOSE:To improve the abrasion resistance by a large margin and increase the degree of a freedom in selection of basic material and improve workability by applying onto the top edge part of a vane with ceramic coating with titanium nitride, titanium carbide, etc., through chemical evaporation or physical vaporization. CONSTITUTION:A vane 8 has a press-contact part 10 curved into semicircular form only at one edge as shown in the figure and is equipped with a rectangular plate body having the stepped parts 11 and 11 where a spring 9 is joined on the other edge. Only the above-described press-contact part 10 is applied with ceramic coating of titanium nitride, titanium carbide, etc., through chemical evaporation or physical vaporization. Thus, the abrasion resistance of the vane 8 and the opponent member is markedly improved, and the reliability for a long period can be maintained. Further, the degree of selection of the basic material for vane is increased, and the workability can be improved, and cost-cut can be realized.
    • 目的:大幅度提高耐磨性,提高基体材料选择自由度,提高加工性,通过在氮化钛,碳化钛等陶瓷涂层上涂覆在叶片的顶缘部上,通过 化学蒸发或物理蒸发。 构成:如图所示,叶片8具有仅在一个边缘处弯曲成半圆形的压接部分10,并且装配有具有阶梯部分11和11的矩形板体,其中弹簧9在另一边缘上接合 。 通过化学蒸发或物理蒸发,仅对上述压接部10涂敷氮化钛,碳化钛等的陶瓷涂层。 因此,叶片8和对手构件的耐磨性显着提高,可以保持长时间的可靠性。 此外,叶片的基本材料的选择程度增加,可以提高加工性,并且可以实现成本削减。
