| titleOfInvention | Metal anticorrosive coating, preparation method and application thereof |
| abstract | The invention discloses a metal anticorrosion coating, which is an inorganic coating and is used for metal anticorrosion. The coating has a double-layer structure, and comprises an outer enamel coating and an inner matrix oxide coating, wherein the content of matrix metal oxide is gradually reduced from the inner layer to the outer layer, so that the thermal expansion coefficient of the coating is gradually increased from the inner layer to the outer layer, and the overall thermal expansion coefficient of the coating is ensured to be consistent with that of various matrix metals. The enamel coating on the outer layer comprises 1-40 parts of silicon, 1-30 parts of sodium, 1-20 parts of potassium, 2-20 parts of calcium, 0.5-15 parts of fluorine, 0.3-10 parts of cobalt, 0.2-10 parts of nickel, 1-18 parts of boron, 0.5-10 parts of phosphorus, 0.1-8 parts of magnesium and the balance of oxygen by weight; the composition of the base oxide coating of the inner layer includes a base metal and oxygen. Also discloses a preparation process of the double-layer compact metal anticorrosive coating formed by low-temperature sintering, which comprises the following steps: 1) grinding; 2) preparing a mixed material; 3) grinding; 4) carrying out high-temperature reaction; 5) grinding; 6) coating; 7) and (5) sintering. The coating disclosed by the invention has the advantages of improving the corrosion resistance by more than 14 times, having high ductility, being capable of performing stretching deformation with a steel bar in a coordinated manner, having a thermal expansion coefficient gradient, and being suitable for different metals and different types of the same metal. |
