The hardness distribution without obviously declining gradient in one range of the hardened layer produced by plasma quenching is rather different from that by conventional quenching.
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。
However, stress re-distribution would occur in the non-uniform structural stress introduced by quenching with a low stress gradient.
而淬火引入非均匀的结构应力且梯度较小，主要发生应力重分布。
