材料特性、生产方法和制造工艺的知识是材料科学学科的重要课题。材料测试方法由几个组织标准化，如ASTM [1]。对材料进行测试，并在手册中列出其机械性能。本文将介绍一项研究，研究如何通过观察样品与砂轮接触时产生的火花来识别一定数量的钢/铸铁。有许多因素可以改变所预测的火花模式，但本文的主要目标是尝试介绍一种火花测试方法及其执行方式。该研究对制造过程中常用的14种不同等级的钢/铸铁进行了研究。一本参考手册是根据对火花图片进行编目的实验数据创建的。本手册可供学生使用，也可供机加工车间使用，以识别所含材料的样品。这可以通过使用相对简单、用户友好的方法来识别车间中的未知库存，从而为机械车间节省大量资金。
Knowledge of material properties, production methods and manufacturing processes are each important subjects in the materials science discipline. Material testing methods are standardised by several organisations, such as ASTM [1]. Materials are tested and their mechanical properties are tabulated in handbooks. This article will explain a study conducted on how a certain number of steels/cast iron might be identified through the observation of the sparks projected when a specimen is held against a grinding wheel. There are many factors that can change the spark patterns that are projected, but the main goal of this article is to attempt to standardise a method of spark testing and how it is performed. The study was conducted on fourteen different grades of steels/cast iron that are commonly used in manufacturing processes. A reference manual was created from the experimental data cataloguing the spark pictures. This manual can be used by students and potentially by machine shops to identify samples of the included materials. This can lead to significant savings for machine shops by using a relatively easy, user friendly method, to identify unknown stock sitting around in the shop.
