Abstract

ABSTRACTThe NiCrMoSiC composite cladding on Titan-31 base alloy was produced using a hybrid microwave heating process. The produced claddings were examined for microstructural, phase analysis, microhardness, and surface roughness using suitable techniques. The linear reciprocator ball on plate wear test was conducted using a static alumina indenter on microwave cladding. Studies have been done on track specifications for friction and wear. It is feasible to fabricate a dense microstructure with uniform distribution of hard phases, absence of pores and fractures, and strong metallurgical bonds. Typically, cladding is two times as durable as the underlying metal. The cladding has a lower coefficient of friction than the substrate as a result of enhanced hardness and improved internal lubricity brought on by the production of hard carbide phases.KEYWORDS: Nickel-ChromiumMolybdenumSilicon CarbideMicrowave Hybrid HeatingCladding Disclosure statementThe authors and the subject of this study do not have any stated conflicts of interest.

SiC和Mo增强NiCr微波熔覆层的显微组织、力学和磨损性能

摘要采用微波复合加热法制备了钛-31基合金的NiCrMoSiC复合包层。使用合适的技术对生产的包层进行了显微组织、相分析、显微硬度和表面粗糙度的检测。采用静态氧化铝压头对微波复层进行了直线往复器球对板磨损试验。已经对轨道的摩擦和磨损进行了研究。制备出硬相分布均匀、无气孔和断口、冶金结合强的致密显微组织是可行的。通常，包层的耐用性是底层金属的两倍。由于硬质合金相的生成提高了熔覆层的硬度，改善了内部的润滑性，熔覆层的摩擦系数比基体低。关键词:镍铬钼碳化硅微波杂化加热包层披露声明本研究的作者和受试者没有任何声明的利益冲突。
