摘要
由于高硬度、高强度、高热稳定性、良好的耐磨性、耐腐蚀性、软磁性、成本低等诸多优点,Fe基非晶合金在众多领域有着十分广泛的应用前景。但其有限的玻璃形成能力、本征脆性等缺点极大地限制其作为工程材料的应用推广。利用热喷涂技术制备的Fe基非晶涂层不仅能够保持其原本的优异特性,还能弥补其缺点,突破工程应用的局限性。本文对Fe基非晶涂层的主要热喷涂制备方法进行了介绍,并对非晶涂层耐腐蚀性的影响因素:成分、氧化、孔隙、晶化和裂纹等一一归纳,并提出了Fe基非晶涂层耐腐蚀性能的优化措施,最后对Fe基非晶涂层耐腐蚀性的下一步研究进行展望。
Because of the advantages of high hardness and strength, superior thermal stability,good wear resistance, excellent corrosion resistance, outstanding soft magnetism, and low cost, Febased amorphous alloys exhibit a broad application prospect in many fields. However, the limited glassforming ability and intrinsic plasticity greatly limit their application as engineering materials. Thereinto, Febased amorphous coatings prepared by thermal spraying technology can not only maintain their inherent characteristics but also avoid the aforementioned shortcomings, thus breaking through the limitation of engineering application. In this paper, the main preparation methods of Fe-based amorphous coatings by thermal spraying were comprehensively introduced, and the influencing factors of corrosion resistance, including the chemical composition, oxidation, pore, crystallization, and crack, were reviewed. Then, the methods to optimize the corrosion resistance of Fe-based amorphous coatings were summarized. Finally,the prospective research regarding the corrosion resistance of Fe-based amorphous coatings was proposed.
