Einfluß der Laserbehandlung auf das Korrosionsverhalten vakuumplasmagespritzter Titan- und Niobschichten

Titanium and niobium coating, produced by vaccum plasma spraying firstly were optimized respectively to porosity by multi factor analysis and secondly were densified and remelted by subsequent CO2-laser treatment. The excellent corrosion properties of these materials could be transferred to the properties of the coating by this process. Effects on microstructure, some specific properties, and the quality of the coations resistance against aqueous solutions. The influence of the laser treatment could be shown by a comparison of conventionally vacuum plasma sprayed coatings, laser-treated coatings and pure material with respect to corrosion resistance.
