The scratch testing technique offers a much higher resolution than conventional peel adhesion testing.The sample is tested as is,without altering the surface and interface with pre-test procedures such as applying a tape or making incisions which can generate micro cracks and other defects.Some results are removed in response to a notice of local law requirement.For more information,please see here.12345NextASTM C1624 - 05(2015) Standard Test Method for Adhesion 5.2 The quantitative coating adhesion scratch test is a simple,practical,and rapid test.However,reliable and reproducible test results require careful control of the test system configuration and testing parameters,detailed analysis of the coating damage features,and appropriate characterization of the properties and morphology of the coating and the substrate of the test specimens.Some results are removed in response to a notice of local law requirement.For more information,please see here.

Scratching definition of scratching by Medical dictionary

Progressive and constant load scratch tests described above were done in three consecutives steps,namely,pre-scan,loaded-scan,and post-scan,(i) Pre-scan measures the initial surface profile of the sample,which is subtracted from the loaded-scan profile to determine the depth of surface penetration,(ii) loaded-scan is a scratch test pass that measures the actual scratch penetration depth Scratch Testing of Hot-Pressed Monolithic Chromium The tribological performance of hot-pressed monolithic CrB2 and a newly developed CrB2 + 20 vol.% MoSi2 composite was investigated by using scratch test.The test was carried out under progressive loading ranging from 0.9 to 30 N over a scratch distance of 3 mm.In situ values of coefficient of friction (COF),depth of penetration and acoustic emission were recorded.Scratch Testing - EP Laboratories,Inc.The scratch testing technique offers a much higher resolution than conventional peel adhesion testing.The sample is tested as is,without altering the surface and interface with pre-test procedures such as applying a tape or making incisions which can generate micro cracks and other defects.
