Problems solved by technology

[0003] However, the metallurgical reaction of high-speed arc spraying used at the present stage is used to obtain intermetallic compound coatings. Due to the fast cooling rate of molten particles and insufficient metallurgical reactions, the obtained coatings have defects such as too little compound content and poor performance.

Abstract

The invention discloses a novel manufacture method of an iron-aluminum thermal spraying powder core wire. The manufacture method comprises the following steps of (a) mixing materials; (b) manufacturing U-shaped steel belts; (c) filling the materials; (d) sealing the U-shaped steel belts; and (e) drawing by using a wire-drawing die. The manufacture method is reasonable in procedure arrangement, convenient to implement and moderate in cost. A thermit reaction is performed on the core wire in the spraying process, so that the metallurgy reaction is full, the core wire is high in quality, iron-aluminum intermetallic compounds can be easily manufactured, a thermal spraying coating has performance of being good in high-temperature vulcanization resistance, high-temperature oxidization resistance and high-temperature corrosion resistance, and the core wire can be widely used.

Description

technical field [0001] The invention relates to a preparation method of iron-aluminum thermal spraying powder core wire, in particular to a preparation method of a novel iron-aluminum thermal spraying powder core wire which is easy to form intermetallic compounds, and belongs to the field of coating technology. Background technique [0002] Intermetallic compounds are materials between metals and ceramics with excellent high-temperature performance, especially iron-aluminum intermetallic compounds, which not only have excellent anti-oxidation, anti-sulfurization properties, corrosion resistance and high high-temperature strength , and does not contain precious metal elements, the preparation cost is low, and it has a very wide range of uses. However, intermetallic compounds have the Achilles heel of high brittleness, which makes it difficult to process and form, which hinders the development of applications. The emergence of arc spraying powder core wire provides a new oppo...
