摘　　要：燃气轮机弹性环是一种薄壁件,在制造过程中极易发生变形。本文介绍了一种弹性环氮化过程防变形装置及方法。利用该装置和方法,有效地控制了弹性环在氮化过程中的变形,极大地提高了合格率。The gas turbine elastic ring is a thin-wall part, and deformation occurs easily during manufacturing. A kind of anti-deformation device and method for the gas turbine elastic ring in the nitriding process were introduced in this paper. By using the device and the method, the deformation of the elastic ring during nitriding is effectively controlled, and the qualified rate greatly improves.
