标准范围

本文件规定了通过在润滑条件下使用球-盘法检测声发射信号来测量ISO 20523中规定的类金刚石碳（DLC）涂层粘附强度的程序。数据链路连接器通常涂覆在金属或陶瓷上。当DLC涂层零件在无润滑环境中工作时，测试结果不适用。

This document specifies a procedure to measure the adhesion strength of diamond-like carbon (DLC) coatings specified in ISO 20523 by detecting acoustic emission signals using ball-on-disk method under the lubricated condition. DLC is normally coated on metal or ceramic.The test results are not applicable when the DLC coated parts operate in an unlubricated environment.
