摘要:
The invention relates to a ceramic coating material comprising ceramic and/or glass-like particles. In order to produce a ceramic coating material exhibiting no volume changes or exhibiting an increase in volume during burning, the invention provides that the ceramic coating material comprises between 10 and 90 wt.-% of reactive components, selected from the group consisting of metals, metalloids, or salts, which react during sintering at temperatures of 370 to 1,500°C in a volume-compensating or volume-increasing manner with gases to form non-volatile reaction products. This results in volume compensation or a volume increase during the burning process, since the reactive components form a reaction with atmospheric oxygen or another atmosphere.

摘要:
The invention relates to a method for coating metal surfaces, whereby at least one layer of a composition is applied to the surface, said composition comprising hydrolyzates/condensates of at least one silane or a silicone resin binder and optionally a suitable solvent, and additionally containing at least one metal filler. The coating is subsequently dried and/or cured.
摘要:
A process for producing a coated metal strip (10) from a semifinished strip (12), in which the semifinished strip (12) is reeled off a coil, a corrosion protection layer (42) is then applied to the semifinished strip (12) and the coated semifinished strip (12) is then reeled up to form a coil, characterized in that the semifinished strip (12) is a cold-rolled strip obtained by cold rolling, cooling and recrystallization annealing, in that a medium (36) containing metallic particles is applied to form the corrosion protection layer (42), where the medium (36) is a wet-chemical solution which is applied by spraying, dipping, squirting, flooding or rolling, and in that the corrosion protection layer (42) is dried on the cold-rolled strip (12) by supply of heat at a temperature below the recrystallization annealing temperature of the cold-rolled strip after application of the medium and before reeling-up.

The invention relates to a method for producing deformable corrosion protection layers on a metal surface and to the use of the method. In order to create an economical method for the cathodic corrosion protection of metal for a broader range of applications, within the scope of the invention a method for producing deformable corrosion protection layers on a metal surface is proposed, comprising the following steps: a) mixing 5 to 95% by weight metal magnesium, zinc, aluminum or titanium particles, or mixtures or alloys comprising at least one of said metals, in the form of pigments, powders, pastes (flakes) or granules, with 5 to 95% by weight of at least one metal compound, wherein a reaction between the metal particles and metal compound(s) results in surface-modified metal particles, b) applying the resulting surface-modified metal particles onto the metal surface, c) compacting the layer produced from the surface-modified metal particles at temperatures between room temperature and 500ºC. Within the context of the invention it has been shown that the coatings according to the invention can be deformed and that the metal substrate coated using the method according to the invention can be deformed, varnished, welded, coated, and dyed and reflects heat.

The invention relates to a process for protecting vehicle body components, chassis components, engine components or exhaust systems from corrosion. In order to provide a process for actively protecting vehicle body components, chassis components, engine components or exhaust systems from corrosion, in which case the layer is to be applied on an industrial scale to standard steel and to sand-blasted press-hardened parts using conventional means (e.g. dipping, spraying, flooding), the invention proposes a process comprising the following process steps: a. using steel alloys which are conventionally used in the construction of vehicle bodies and vehicles or using hot-formed or press-hardened vehicle body components, chassis components, engine components or parts of exhaust systems which are provided with metallic coatings or metal-pigment-containing coatings or with such coatings for protection against scaling, b. using conventional joining processes to join together at least two vehicle body components, chassis components, engine components or parts of exhaust systems, which differ in composition, process undergone or surface coating, to form a composite, wherein at least one of the components joined together to form the composite is a hot-formed or press-hardened component, c. applying an anti-corrosion coating to the composite.
