Definitions
- the present invention relates to polysilazane-based coatings for the production of a protective coating for metal surfaces to prevent scale formation and corrosion protection at high temperatures.
- the necessary heat treatment for annealing or tempering the components in the range of about 900 to 1250 0 C to the oxidation of the metal surface and an associated discoloration.
- the formed scale, oxidation products of iron, must be removed consuming.
- DE 1803022 describes a ceramic protective coating, which avoids the formation of scale and, due to its very different from the steel thermal expansion coefficient flakes off during cooling and thus provides temporary protection. Disadvantages are u.a. the use of toxic lead compounds, the high stoving temperature, the inherent color (not transparent) and the temporary use of this protective coating. In addition, this protective coating is between 100 and 200 microns thick and thus requires a high material consumption.

- Particularly suitable solvents for the perhydropolysilazane formulation or the ABSE formulation are organic solvents which contain no water and no reactive groups (such as hydroxyl or amine groups). These are, for example, aliphatic or aromatic hydrocarbons, halogenated hydrocarbons, esters such as ethyl acetate or butyl acetate, ketones such as acetone or methyl ethyl ketone, ethers such as tetrahydrofuran or dibutyl ether, and mono- and polyalkylene glycol dialkyl ethers (glymes) or mixtures of these solvents.

- Coating with the polysilazane formulation may be by methods commonly used in the paint industry. These may be, for example, spraying, diving or flooding. Subsequently, a thermal aftertreatment can be done to cure the coating to accelerate. Depending on the polysilazane formulation used and, if appropriate, the catalyst, the curing takes place already at room temperature.
- the invention therefore further provides a process for producing a protective layer on a metal, wherein the polysilazane solution optionally containing catalyst and fillers is applied to the metal by suitable methods such as, for example, spraying or dipping and then cured at room temperature.
- thermolysis which is the ceramization of the
- Polysilazane coating causes. This thermolysis is carried out in a pyrolysis oven on air or other gases such as argon, nitrogen, ammonia, etc. Typically, is pyrolyzed in air.
- the heating rate is typically 3 K / min up to a temperature of 500 ° C. to 1500 ° C., preferably up to 800 ° C. to 1200 ° C., more preferably up to 1000 ° C.
- the holding time at the maximum temperature is typically 10 min. - 10 h, preferably at 30 min. to 4 h, more preferably 1 h.

- 1st step Chemical bonding of the polysilazane layer to the metal substrate by reaction of the oxidic metal surface with the polysilazane (formation of a (substrate) metal O-Si (polysilazane layer) even at room temperature)
- 2nd step During the pyrolysis, the conversion of the polysilazane into silicon dioxide or a polysiloxane takes place.
- the layer thus obtained (optimum layer thickness 0.5 to 1.5 ⁇ m) adheres excellently, is flexible (substrate can be bent without the layer tearing), has excellent diffusion stability against oxygen and moisture and is chemically very stable.
- the cured coating has a thickness of 0.1 - 10 microns, preferably 0.2 to 5 microns, more preferably 0.5 to 1, 5 microns and ensures excellent protection of the surfaces from corrosion and oxidation.

- the coating according to the invention was applied to various steel grades, to copper and to magnesium. It is transparent and thus does not affect the natural appearance of the metals, the coating is rather not visible at all. It offers permanent protection even under extreme conditions.
