Title
(EN) Initial Wetting Auxiliary Material for a Vaporiser Body
Abstract
(EN)

An initial wetting auxiliary material is for applying to a vaporiser surface of an electrically heatable ceramic vaporiser body. The vaporiser body is used for operation in a physical vapour deposition (PVD) metallisation installation for vaporising aluminium. The vaporiser body contains nitrogen as a material component. The auxiliary material comprises a powder mixture which comprises (a) aluminium in powder form having a particle size which is at most 0.6 mm. The aluminium in powder form melts on the vaporiser surface after initiating the operation of the vaporiser body and reacted with the nitrogen of the vaporiser body to form an aluminium nitride layer on the vaporiser surface. The powder mixture further comprises (b) a wetting agent in powder form promoting an even and large-surface distribution of the molten aluminium on the vaporiser surface.
