标准摘要
[中文适用范围]： 本文件规定了通过化学蚀刻方法检测和分类研磨表面局部过热的程序和要求。本文件中描述的工艺通常用于研磨表面；但是，它也可用于检测由热处理后加工（例如硬车削、铣削和边缘断裂（去毛刺）工艺）引起的表面异常。通过此工艺，还可以很容易地检测到由渗碳或脱碳引起的表面冶金异常。过去使用的一些方法不再推荐。规范旨在更改为使用本文件中的方法。这些蚀刻方法对表面硬度变化的敏感度高于大多数硬度测试方法。本文件适用于钢制零件，例如齿轮、轴、花键和轴承。它不适用于氮化零件和不锈钢。注意：此工艺有时称为“硝酸盐蚀刻”，但不应与其他也称为“硝酸盐蚀刻”的工艺相混淆。表面回火蚀刻程序是在研磨之后和超精加工、喷丸和珩磨等其他精加工操作之前进行的。 [外文原描述]： ISO 14104:2017 specifies procedures and requirements for the detection and classification of localized overheating on ground surfaces by chemical etch methods. The process described in this document is typically used on ground surfaces; however, it is also useful for the detection of surface anomalies that result from post-heat treatment machining such as hard turning, milling and edge breaking (deburring) processes. Surface metallurgical anomalies caused by carburization or decarburization are also readily detectable with this process. Some methods which have been used in the past are no longer recommended. Specifications are intended to be changed to use the methods in this document. These etching methods are more sensitive to changes in surface hardness than most hardness testing methods. ISO 14104:2017 applies to steel parts such as gears, shafts, splines and bearings. It is not applicable to nitrided parts and stainless steels. NOTE This process, although at times called "nital etch", is not intended to be confused with other processes also known as "nital etch". The surface temper etch procedure is performed after grinding and before additional finishing operations such as superfinishing, shot peening and honing.
