Iron-based amorphous powder cored wire containing MXenes and preparation method and application of iron-based amorphous powder cored wire.

Abstract

The invention discloses an iron-based amorphous powder cored wire containing MXenes and a preparation method and application of the iron-based amorphous powder cored wire. The wire comprises 98.5-99.5wt.% of FeSiB and 0.5-1.5 wt.% of MXenes. The iron-based amorphous powder cored wire is prepared by coating a powder core with a stainless steel belt, the powder core is formed by mixing seven kindsof element powder, and the powder core is prepared from, by weight percent, 38% of Cr, 2% of C, 4% of Si, 3% of Ni, 5% of Co, 10% of Zr and the balance Fe. MXenes is at least one of Ti3C2Tz, Zr3C2Tz and Hf3C2Tz (Tz=O, F, OH); and the stainless steel belt is 310S stainless steel, and the weight ratio of the powder core to the stainless steel belt is 0.8: 1. According to the application of the iron-based amorphous powder cored wire containing the MXenes to a high-corrosion-resistance iron-based amorphous / MXenes composite protective coating, the coating is prepared by adopting an electric arc spraying technology. The protective coating with high bonding strength and excellent corrosion resistance is obtained, is suitable for the surface of a part working under severe working conditions such as a marine environment, is easy to industrialize and has a wide application prospect.

Description

technical field [0001] The invention belongs to the thermal spraying field of material processing engineering, and in particular relates to an iron-based amorphous powder core wire material containing MXenes and a preparation method and application thereof. Background technique [0002] With the development of science and technology, the service environment of various metal components is becoming more and more complex. The highly corrosive environment such as the ocean seriously reduces the performance of metal components and shortens their service life. Therefore, the development of new high-corrosion-resistant metal materials has become an urgent need. solved problem. Iron-based metal materials are one of the most cost-effective metal types, but their corrosion resistance is often poor. [0003] Due to the long-range disordered atomic structure of iron-based amorphous materials, there are no defects such as grain boundaries and dislocations inside the material, so its cor...

Problems solved by technology

However, in order to obtain a higher amorphous content in the existing arc sprayed iron-based amorphous coatings, the chromium content is usually low. In addition, there are inevitably pores, oxides and crystalline phases in the thermal sprayed amorphous coatings. These lead to localized chromium-depleted areas in the coating, which reduce the corrosion resistance of the coating
