Scratch testing
Test for qualitative or quantitative characterization of thin films and coatings. This measurement is performed by applying a force, generally increasing, to an indenter, and moving the coated sample under the indenter.
Sclerometry; Sclerometry
Measurement of the hardness of solids based on their resistance to scratching.
Adhérence ; Adhesion
All the forces between two materials that prevent them from separating.
Charge critique ; Critical load
Normal force leading to systematic damage (spalling, cracking, etc.).
Émission acoustique; Acoustic emission
Energy release in the form of transient elastic waves.
Coefficient or friction...
