Abstract
本发明公开了一种超高速激光熔覆Fe基非晶复合耐磨涂层及制备与应用，属于表面工程技术领域。该方法包括基材预处理、涂层粉末准备、超高速激光熔覆三个步骤，具体采用铁基非晶合金粉末与TiC陶瓷粉末为原料，利用超高速激光熔覆技术在基材表面进行沉积。通过极高的冷却速率与精准的热输入控制，涂层保持了高非晶含量，并与基体形成了极窄的冶金互扩散带。所制备的复合涂层具有极高的显微硬度，且在中高温工况下能通过原位摩擦化学反应生成致密的复合氧化物纳米晶自润滑釉质层，展现出卓越的“热致抗磨”特性。本发明能显著降低构件的磨损量与粉尘排放，特别适用于新一代低排放车辆刹车盘及其他高端耐磨零部件的表面防护。
