Abstract
In this paper we report on an original laser surface treatment which uses two Nd-YAG laser beams in conjunction with a thermal spray gun in order to modify the substrate surface prior to thermal spraying in order to enhance the adhesion at the coating substrate interface. A first Nd-YAG laser is used to heat the surface and a second to clean it. The system is used to coat two different materials (titanium Ti-6Al-4Â V and aluminium 2017 alloy) with a Ni-Al alloy. The relation between the surface modifications induced by these treatments and the adhesion of the coatings on the substrates are studied.
