Fabrication and Corrosion Resistance of Al-Co-Ce Amorphous Alloy Coating by a Combined Process of Thermal Spraying and Pulsed Electron Beam Surface Remelting
The surface modification technology based on high current pulsed electron beam (HCPEB) can eliminate the porous structure of thermal sprayed coatings and obtain amorphous coatings with excellent corrosion resistance. In this study, Al-Co-Ce master alloy and powder were firstly prepared, followed by the preparation of an Al-Co-Ce alloy coating on Q235 steel substrate using high velocity flame (HVOF) spraying technology. Finally, HVOF sprayed coating was irradiated and remelted by HCPEB to change its porous crystalline microstructure into dense and amorphous form which greatly enhances its corrosion resistance. The combination of thermal spraying and HCPEB surface remelting proposed in this study provides a new process for preparing Al-Co-Ce amorphous alloy coatings.
