球墨铸铁激光表面淬火硬化深度的解析计算

摘要

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.%为了简单快速地得到激光表面淬火的硬化深度,利用激光加热过程中的半无限体表面点热源热扩散公式,在分析激光表面淬火相变硬化基本规律的基础上,对激光表面淬火硬化层深度的解析计算公式进行了推导和试验验证,并取得了较为理想的数据.结果表明,在现有试验条件下该计算方法是高效和正确的.
