Stainless steel (SS) 410 is widely used in many components of nuclear reactors due to its good corrosion resistance and high strength. However, wear is a major issue of these components due to its continuous sliding. SS 420 and Colmonoy 5 particles were deposited over SS 410 substrate by laser cladding process. Then, X-ray diffraction was used to find the phases present after cladding process. Further, coating morphologies were analysed by scanning electron microscopy (SEM) twinned with energy-dispersive spectroscopy. The obtained morphology indicates the hard laves phase present in the Colmonoy 5 cladding surface and needle-like structure in SS 420 cladding surface. Then, Vickers microhardness test was carried out in order to study the hardness and load-carrying capacity of the cladding specimen. Among those, Colmonoy 5 cladding specimen provide higher hardness due to the presence of laves phase formation. Then, the dry sliding wear study was conducted to calculate the mass loss after 2500 m of sliding. The combined effect of hardness and laves phase formation were reflected in dry sliding wear study analysis of the specimens. Then, to study the wear mechanism and roughness, worn surface morphologies were captured using SEM and white light interferometer, respectively.

不锈钢（SS）410由于其良好的抗腐蚀性和高强度而被广泛用于核反应堆的许多组件中。然而，由于其连续滑动，磨损是这些部件的主要问题。通过激光熔覆工艺将SS 420和Colmonoy 5颗粒沉积在SS 410基板上。然后，使用X射线衍射查找包覆过程后存在的相。此外，通过与能量色散光谱法配对的扫描电子显微镜（SEM）分析了涂层的形态。所获得的形态指示在Collmonoy 5包层表面中存在硬熔岩相，在SS 420包层表面中存在针状结构。然后，进行维氏显微硬度测试，以研究包层试样的硬度和承载能力。在这些，由于存在Laves相形成，Colmonoy 5熔覆样品提供了更高的硬度。然后，进行了干式滑动磨损研究，以计算2500 m滑动后的质量损失。在样品的干滑磨损研究分析中反映了硬度和熔渣相形成的综合作用。然后，为研究磨损机理和粗糙度，分别使用SEM和白光干涉仪捕获了磨损的表面形貌。
