环形锻件激光表面淬火的热处理方法的特征在于局部，即使是形状复杂的部分，也只是作为耐磨损性所需的部分选择性地硬化，与过去的方法可以得到比同等程度或更高的硬度进行比较。现在，激光加工，切割，钻孔中心是人气。更少的应用程序热处理。但是，如果是本机的输出功率，即使在同一台机器，通过光的研究中，也可以进行热处理，如果目的开发的机械部件，环形锻件激光热处理的场是需要在未来发展。

　　The characteristics of heat forging processing method of laser surface hardening is local, even in the complex form, is selectively required as part of the wear resistance of the hardened, and the past can be obtained than the same degree or higher hardness compared. Now, the laser processing, cutting, drilling center is popular. Fewer applications heat treatment. However, if the output power of this machine, even on the same machine, by the light of the study, can also carry out heat treatment, if the development of mechanical parts, forging laser heat treatment is needed in the future development.

　　一方面，可以通过研究发现了许多重大的问题。激光热处理的锻造变形很少，例如，尽管这一点，通过X射线测定所测定仍具有残余应力和残余奥氏体的极大值，可以将其携带的尺寸变化的材料的限制。此外，像见'刚度分布，淬火硬度显著的部分和空白的变化。使用;也有可能剥离现象。我们认为，分区和轻填充激光热处理部的未来锻件，仍调查中的实际的材料和动态机械性能的影响方面的潜在回火问题。

　　On the one hand, many important problems can be found through research. The forging of laser heat treatment deformation is very few, for example, in spite of this, the X ray determination determination of residual stress is the maximum force and residual austenite, can be the size change of its carrying materials limited. In addition, like see 'stiffness distribution, quenching hardness, significant parts and blank changes. Use; also possible peeling phenomenon. We suggest that the partitioning and light filling of future forgings in the laser heat treatment section are still investigated in terms of the actual material and dynamic mechanical properties in terms of the potential tempering problem.
