NEW ADVANCES FOR LASER ADHESION TEST (LASAT) : FROM THICK TO THIN COATINGS

摘要

This paper present recent developments in LAserrnAdhesion Test. This technique sollicitates materialrninterfaces with laser driven shock wave. Results showrnthe ability of the technique to do a quantitativernadhesion test for wide range of material andrnconfiguration. Edge effect principle and ultra-shortrnshock wave give perspectives for new applications forrnthick and thin coatings. Fundamental principles arernevidenced through experiments on bulk ductilernmaterials before demonstrating their application torncoated systems.
