| Objective To further enhance the properties of Fe-ZrO2 Nanocomposite ceramic coating. Methods The Fe-ZrO2 nanocomposite ceramic coating was prepared on 45 steel surface by electrodeposition and then processed by laser remelting coating. A set of orthogonal experiments were used to analyze the effects of laser remelting parameters on the coating microstructure, hardness and binding force and optimize the remelting process. Results The optimized process was drawn as the followings: current 150 A, impulse width 8ms, frequency 15 Hz, scan rate 250 mm / min, negative defocus amount 2 mm. After the laser remelted, the coating hardness had been improved, nanoparticles had been refined, the metallurgical bond had been formed between the coating and substrate. Conclusion The results show that after the laser remelting, the morphology and properties of Fe-ZrO2 nanocomposite ceramic coating have been improved. |
