Wire mesh flexible composite fabric for surface modification and preparation method of wire mesh flexible composite fabric

Abstract

The invention relates to a wire mesh flexible composite fabric for surface modification and a preparation method of the wire mesh flexible composite fabric. The wire mesh flexible composite fabric comprises wolfram carbide (WC) or WC-cobalt (Co), mechanically alloyed nickel-chromium alloy powder, a forming agent and a binding agent. The wire mesh flexible composite fabric for surface modification is made through roll forming. By adopting a mechanical alloying technology, a nanocrystalline technology and a wire mesh technology, the preparation forming property of the flexible fabric is greatly improved, the thickness of the flexible fabric is extremely controlled, and the design idea of gradient coatings of more than two layers can be realized, so that the stress is reduced and the welding texture and the welding property are improved. The WC coating with excellent performance is prepared.

Description

technical field [0001] The invention relates to a wire mesh flexible composite 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. [0003] Traditional surface coatings such as pre-clad coatings, wear-resistant coatings, spray welding, surfacing, thermal spray coatings, etc. still have serious deficiencies and disadvantages in terms of wear resistance, heat transfer and operation requirements, and can only provide ...
