Problems solved by technology

Traditional brazing materials are usually prepared by preparing powdery brazing material, cemented carbide particles, adhesives, organic matter, etc. into suspended slurry-like brazing materials or sheet-like brazing materials, and then coated or adhered to the surface of the workpiece. In order to prevent the oxidation of the base metal and powdered solder and promote the wetting and spreading of the solder on the surface of the cemented carbide particles and the base metal, it is often necessary to continuously add flux during the brazing coating process, which is low in work efficiency and easily causes a large amount of flux waste, high cost

Abstract

The invention discloses a tubular braze coating material. The tubular braze coating material is of a double-layer filament-shaped or strip-shaped structure shaped like a belt core, the outer layer is a brazing alloy wrapping layer, and the inner layer is composed of mixtures of hard alloy particles and brazing flux. The mixtures are composed of, by weight, the hard alloy particles of 80-90% and the balance brazing flux. Compared with traditional suspending slurry braze coating materials or sheet braze coating materials formed by powdery brazing filler metal, hard alloy particles, adhesives, organic matter and the like, the tubular braze coating material has the advantages that the brazing flux is contained internally, quantitative and automatic addition of the brazing flux is realized in the braze coating process, the proportion of brazing alloy and the proportion of the hard alloy particles are uniform, the hard alloy particles are uniformly distributed after braze coating, and storage, transportation and use are convenient.

Description

technical field [0001] The invention relates to a tubular brazing coating material, in particular to a tubular brazing coating material with self-contained brazing flux, good formability, consistent proportion of brazing material alloy and hard alloy particles, and convenient use. Background technique [0002] Partial surfaces of some workpieces are often required to have high wear resistance and corrosion resistance. If the workpiece is made of an overall wear-resistant alloy or corrosion-resistant material, not only the cost is high, but also the overall mechanical properties often cannot meet the requirements. A reasonable solution is usually to use surface treatment technology to coat a layer of wear-resistant or corrosion-resistant metal or alloy on the working surface of the workpiece. As far as the wear-resistant layer is concerned, the commonly used methods are physical vapor deposition (PVD), chemical vapor deposition (CVD), thermal spraying, surfacing and brazing....
