| Summary: | This study investigates laser cladding of Monel 400 alloy with a Stellite 6 coating for marine and offshore applications. This report addresses the gap in knowledge on material compatibility and defect analysis in laser cladding of these alloys. The research has three key goals. First, to evaluate the mechanical properties, particularly the hardness, of the clad layer. Second, to identify the optimal laser cladding parameters that will achieve the desired properties. Finally, analyze the relationships between the process parameters, microstructure, and mechanical performance.
Fifteen samples with varying laser power, scan speed, and powder feed rate are fabricated. Microstructural analysis, Vickers hardness testing, and Energy-Dispersive Spectroscopy (EDS) were utilized for investigation of the clad layer. This study examines the impact of process parameters on defects, porosity, dilution rate, hardness, and elemental composition, thus aiming to establish possible correlations or relationships between these factors and achieve optimal performance. |
