The hardness distribution without obviously declining gradient in one range of the hardened layer produced by plasma quenching is rather different from that by conventionalquenching.
等离子表面淬火硬化层的硬度分布，在某一区域内无明显的硬度梯度，这与常规淬火方法的结果不太一样。

The result shows it is viable that 45 steel ooze boron oil quenching replacing conventional 45 steel found produces tower wheel in water tank drawbench .
用45钢渗硼油淬用来代替传统的45钢铸造生产水箱拉丝机中的塔轮是可行的。

The quenching deformation of complex sections can not be avoided because it is not easy to control the deformation with conventional method.
