Abstract: A method for coating metal surfaces, excluding lithographic plates, includes either, in the sequence specified, (a) a step involving mechanical and/or chemical roughening of the metal surface to be coated; and a step involving coating of the roughened surface, wherein a layer with a thickness ranging from 100 nm to less than 1 ?m is applied, or introducing a secondary phase as the roughening step at the same time as the coating step, wherein a layer with a thickness ranging from 100 nm to less than 1 ?m is applied. A component produced with the method is also provided.

Abstract: Domestic appliances are provided with a catalytic deodorizing coating, prepared by applying a coating material containing a polycondensate of at least one hydrolysable organosilane, optionally one or more compounds of glass-forming elements, and particles of one or more catalytically active transition metal oxides, and then heat-treating the applied coating material.

Abstract: The invention relates to domestic appliances bearing on a powder-coated surface a scratch-resistant and abrasion-resistant topcoat of a coating material which comprises: a) condensates based on hydrolysable silanes containing at least one non-hydrolysable substituent, the hydrolysable silanes having an epoxide group on at least one non-hydrolysable substituent; b) a curing catalyst selected from Lewis bases and alkoxides of titanium, zirconium or aluminium; c) nanoscale particulate inorganic solids having a particle size in the range from 1 to 100 nm; and d) at least one organic monomer, oligomer or polymer containing at least one epoxide group.

Abstract: A catalytic converter for use in an oven includes at least two sub-catalysts connected in series. One of the sub-catalysts includes a catalytically active metal layer as its active surface to improve the efficiency of the catalytic converter with respect to the elimination of unpleasant odors. The one sub-catalyst includes a metal oxide as its active surface. At least one other sub-catalyst includes, as its active surface, a metal layer selected from elements in groups 8 to 10 of the periodic table.

Abstract: A baking oven includes a metallic baking oven muffle that can be closed off on a front side by a door. The muffle walls have heating elements for heating the cooking chamber to over approximately 180° C. and/or for heating the food disposed therein to be cooked. The muffle has a protective layer covering the muffle walls at least on the inner side. To improve the use properties of the baking oven muffle, the thickness of the protective layer is less than approximately 30 &mgr;m. The protective layer is formed as a hard sol-gel layer having a thickness of approximately 10 &mgr;m, preferably, between approximately 5 and 10 &mgr;m. The protective layer is transparent. The inner sides of the muffle serve as a reflector. A functional sol-gel layer is disposed on the hard sol-gel layer. The functional sol-gel layer has a thickness of approximately 10 &mgr;m, preferably, 2 to 3 &mgr;m. When the muffle is aluminum, the protective layer is an anodized aluminum oxide layer.
