开发了一个基于PC机的软件包，便于生成激光相变硬化程序。该软件包包括基于模型的过程模拟模块、基于标准化参数记录的图形用户界面、已完成程序的数据库和处理成本分析。热流和相变的分析模型用于预测转化区的深度和开发的最大硬度，在主要工艺变量（激光束参数和材料特性）方面。实验数据和模型预测之间的良好协议被证明为一系列的合金钢。因此，可以获得用于实验评估的真实的处理参数集，从而显著减少试错测试的量。可以检索存档的程序进行编辑和进一步开发。加工成本可以很容易地与传统的表面硬化技术进行比较。
A PC-based software package has been developed which facilitates the generation of procedures for laser transformation hardening. The package comprises a model-based process simulation module, a graphical user interface based on a standarized parameter record, a database of completed procedures, and a processing cost analysis. Analytical models of heat flow and phase transformations are used to predict the depth of the transformed zone and the maximum hardness developed, in terms of the principal process variables (the laser beam parameters and material properties). Good agreement between experimental data and model predictions is demonstrated for a range of alloy steels. Realistic sets of processing parameters can thus be obtained for experimental evaluation, reducing the amount of trial-and-error testing significantly. Archived procedures can be retrieved for editing and further development. Processing costs can be compared readily with those for conventional surface-hardening techniques.
