Scope
This document specifies a test method for measuring the adhesion of diamond-like carbon (DLC) coated components as defined in ISO 20523 under lubricated conditions by detecting acoustic emission signals using the ball-on-disc method. Diamond-like carbon coatings are typically applied to metal or ceramic substrates.
The test results are not applicable to the unlubricated working conditions of DLC coated parts.
