Metal flexible cloth for metal surface modification and preparation method thereof

Abstract

The invention relates to a special metal flexible cloth for the preparation of a coating with high temperature and corrosion resisting and a preparation method thereof. The metal flexible cloth can be used for the protection of mechanical parts in fields, i.e. a power station, petroleum, aviation, food, plastic, and the like. The metal powder cloth is prepared by adding a forming agent and a bonding agent into the mixed power of metals, i.e. WC-Co, Ni, Cr, and the like, and the cloth patch can be bonded on a metal base body by an organic bonding agent to form a thicker protective layer with abrasion resistance, high temperature resistance and corrosion resistances by being metallurgically combined with the metal base body in a penetration brazing way. The coating has good heat conductivity, corrosion resistances and impact resistance, and wrapped parts can recover the original mechanical property of base materials through heat processing, thereby, the costing can be suitable for the recovery of pieces with heterogeneous surfaces and especially suitable for the recovery of a curved surface, a folded surface, a helical surface, and the like. The invention an solve the problems of the high temperature corrosion and the abrasion of parts with serious abrasion and heat resistance in mechanical equipment and power station equipment, decreases the times of stopping production for overhauling and enhances the economic benefits.

Description

technical field [0001] The invention relates to a metal flexible cloth specially used for preparing high-temperature and corrosion-resistant coatings and a preparation method thereof. It can be used for the protection of mechanical parts in power stations, petroleum, aviation, food, plastics and other fields. Background technique [0002] Friction, wear and corrosion are the main forms of failure of metal workpieces in various mechanical equipment, and the resulting economic losses caused by increased energy and material consumption are huge. Therefore, research on metal wear and wear-resistant and corrosion-resistant materials has always been Wide attention at home and abroad. Many components of mechanical equipment have requirements for anti-wear, anti-corrosion or high temperature resistance. In a sense, the reliability of mechanical equipment depends on the degree of anti-corrosion and anti-wear of its key components. Solving the problems of anti-corrosion and anti-wear...
