| Abstract: | In order to obtain the hardening depth that treated with laser surface hardening simply and immediately,the process of laser surface hardening was analyzed and an analytical equation was concluded based on the semi-infinite surface point heat thermal diffusion equation,at the same time the experiment was conducted and ideal results were obtained.The method is right and efficient verified by the experimental results under existing experimental conditions. |
