| 中文摘要 | 针对瓦楞辊工况下强烈的干摩擦磨粒磨损,开发了一种专门针对瓦楞辊的旨在大幅提高耐磨性的激光熔覆材料体系。通过工艺优化,在新辊或失效辊表面激光熔覆制备了无气孔裂纹等缺陷、厚度大于0.4mm的耐磨涂层。熔覆层与基体呈冶金结合,平均显微硬度915HV0.2。该工艺已经用于工业生产,实践证明该技术相对于已有的方法如氮化、激光相变硬化、镀铬、喷涂碳化钨在性能、成本、寿命、可修复性等方面具有综合优势,有广阔的应用前景。; A unique cladding powder material to harden corrugating rollers surface was developed to tackle the severe dry friction abrasive wear.After laser cladding with optimized parameters,a crack-free coating with thickness over 0.4mm was obtained.This coating with average hardness of 915HV0.2 has strong metallurgic bond with the substrate.The technology has been applied to industrial production,which demonstrates comprehensive advantages on cost,lifetime,technique stability and rejuvenation capability compared with present hardening technologies like intermediate frequency quenching,nitrogen hardening,chromeplate,laser transformation hardening,and tungsten carbide spraying. |
