Wettability and Surface Free Energy of Ti(C,N) Coatings on Nickel-based Casting Prosthetic Alloys

Abstract

The production process of prosthetic restorations runs in two stages. In the first stage, the prosthetic foundation is produced of metal alloys. In the second stage, a facing material is applied on the produced element. In both stages, the wettability is significantly important, as well as the free surface energy relating to it. The quality of the obtained cast depends on the surface phenomena occurring between the metal alloy and the material of which the casting mould is made. The performed examinations also point to a relation between the ceramics joint and the base, depending on the wetting angle.
