Method fr preparing electric arc spraying fiber material containing core of nano material

Abstract

An arc-spraying wire with the core containing nano material features that its core is a composite powder containing nano material and its jacket layer is chosen from carbon steel band, chromium steel band, stainless steel band, nickel band and aluminium band. Its sprayed layer has high adhesion and resistance to abrasion, crossion and oxidization.

Description

Technical field

[0001] The invention relates to the processing or treatment of wires, in particular to a method for preparing electric arc spraying wires containing nanomaterial drug cores. Background technique

[0002] Due to high-temperature erosion and wear of fly ash and high-temperature corrosion of flue gas, the boiler pipes of coal-fired power plants have reduced the wall thickness of the "four pipes" (water wall pipes, superheater pipes, reheater pipes, and economizer pipes). Small, a pipe burst accident occurred, causing huge losses to the power plant. Traditional methods, such as adding welding angle iron, anti-wear tile protection or directly replacing the pipe, not only seriously affect the thermal efficiency, but also uneconomical, and the anti-wear and anti-corrosion effect is not good. Spraying common drug core wire material, the effect is also unsatisfactory. Contents of the invention
