A process - metallic, thermally sprayed layers on natural stone, clay articles, sanitary fixture - and table ceramic and gypsum molds to the wear resistance and surface finishing

摘要

For the production of clay - and ceramic goods gypsum molds are used, which are subject to high wear. Gypsum is used as a mold material, in order in the case of a smooth surface, the required porosity to ensure, for the drying of the slip. By means of which have previously been used the method was the creation of a wear guard layer, while maintaining the required porosity is not possible. It was furthermore not possible to date, metallic - usable cover layers to design purposes in the desired layer thickness and in any desired, the design form on natural stone, clay articles, sanitary fixture - and table to apply ceramic. Dollars a in order to improve the wear behavior on gypsum molds, metallic layers are used, which the required porosity is maintained because. This is achieved by the application of the metallic protective layer by means of thermal spraying processes. Dollars a metallic cover layers are also to design purposes by thermal spraying directly applied. It can be nearly of each metal or alloy in wire -, - or powder form are applied. Dollars a the application of plaster protection against wear. Furthermore the production of new metal surfaces on ceramic -, natural stone - or clay products to design purposes.
