The aim of this Study was to compare three adhesion tests carried out on plasma-sprayed copper coatings on aluminium Substrates. The first test, the bond pull test, designated EN 582 or ASTM C633. involves a uniaxial static stress and is commonly used in the coating industry. The second test, the LASAT (LASer Adhesion Test). is a recently developed technique based on spallation phenomenon due to laser induced shock waves. In this test, the coating delamination results from spallation at the coating/substrate interface due to uniaxial tensile stress. The last test, the bulge and blister test, involves a quasi-static measurement of the crack propagation energy at the coating/substrate interface. These three techniques have been used to evaluate the influences of different process parameters involved in the coating adhesion such as aluminium surface roughness, substrate pre-heating and plasma spray conditions.
