一种超声振动同步辅助FCAW-S堆焊铁基耐磨熔覆层的制备方法

本发明属于表面工程与耐磨材料电弧增材制造技术领域，具体涉及一种超声振动同步辅助FCAW‑S堆焊铁基耐磨熔覆层的制备方法。针对传统自保护药芯焊丝堆焊铁基熔覆层组织粗大、气孔多发、易开裂、耐磨性不足的问题，在FCAW‑S堆焊过程中同步施加超声振动，旨在改善熔池流动性与元素分布，以改善显微组织的均匀性‑细化晶粒并提升耐磨性，获得熔渗均匀‑气孔少‑组织细化的高质量耐磨熔覆层，利用空化与声流效应扰动熔池、细化晶粒、促进气泡逸出、降低残余应力。本发明采用高碳高铬自保护药芯焊丝，协同调控堆焊与超声参数，获得致密无裂纹的细晶熔覆层，硬度与耐磨性显著提升，适用于矿山选矿弯头等冲蚀磨损复合工况。
