<p>Laser cladding (LC) is an effective method for enhancing the mechanical and surface characteristics of metal alloys and metal matrix composites. Various factors, including cladding shape, microstructure, dilution ratio, defects, distortion, surface quality, and metallurgical changes in the base material, can influence the quality of the cladding layer. This research is specifically examining the shape, hardness, and dilution ratio of cladding layers made from martensitic stainless steel (17-4PH). Numerous parameters related to laser cladding, such as powder feed rate, cladding speed, laser focus, and laser power, have been taken into consideration. Additionally, the study focuses on achieving desired geometric shapes and preventing porosity on the cladding surface. By optimizing parameters like scanning speed, powder feed rate, and laser power, a minimal dilution of approximately 9% was achieved. The findings indicate that proper distribution of cladding powder can result in a uniform cladding surface. Furthermore, the use of 17-4PH powder led to a notable enhancement in the micro-hardness of the cladding layer.</p>
