In the present investigation microwave energy has been utilized to develop wear resistant Ni-based clad without Nd₂O₃ (unmodified coating) and with addition of Nd₂O₃ (modified coatings) in varying wt. % of 1-3. The clads have been developed using domestic microwave oven at frequency of 2.45 GHz and power 900 W for duration of 360 s. The unmodified and modified clads have been characterized in terms of microstructure, XRD, microhardness and two body abrasive wear. The average thickness of developed clads has been measured as 1.0 mm approximately. A two body abrasive wear behaviour of unmodified and modified coatings at sliding speed of 36 m/min & 72 m/min with abrasive grit size of 220 & 600 has been investigated. The results revealed a better abrasive wear resistance at lower sliding speed and fine grit size. Further, the best results of microstructure, formation of hard phases, improved microhardness and wear resistance have been shown by the samples having coating composition as 3 wt. % of Nd₂O₃.

稀土对镍基微波熔覆层组织和磨损行为的影响

在本研究中，微波能已被用于开发不含Nd ₂ O ₃（未改性涂层）和添加Nd ₂ O _3的耐磨Ni基包覆层（改性涂料）的不同重量 1-3的百分比。使用家用微波炉以2.45 GHz的频率和900 W的功率在360 s的持续时间内开发了包层。未经修饰和经修饰的包层已经在微观结构，XRD，显微硬度和两体磨料磨损方面进行了表征。已测得的包层的平均厚度约为1.0毫米。研究了未改性和改性涂层在滑动速度分别为36 m / min和72 m / min，磨料粒度为220和600时的两体磨料磨损行为。结果表明，在较低的滑动速度和细粒度的情况下具有更好的耐磨性。此外，涂层组成为3重量％的样品显示出最佳的微观结构，硬相形成，改善的显微硬度和耐磨性的结果。钕含量₂ O ₃。
