With the development of society and economy, there is an increasing demand for surface treatment techniques that can efficiently utilize metal materials to obtain good performances in fields mechanical engineering aerospace industry. The laser deposition (LMD) technique cladding has become a research focus recent years because its lower dilution rate, small heat-effect zone metallurgical bonding between coating substrate. This paper reviews simulation technology melt pool’s grain growth mechanism, temperature stress distribution are directly related defect formation LMD technology. At same time, suppression method performance improvement cladded layer introduced. Finally, it pointed out active selection according required performance, combined with controllable processing technology, form corresponding microstructure, finally, actively realize expected function, future direction

Protection against microbiologically influenced corrosion (MIC) is critical for materials used in aquatic environments, as MIC accelerates material degradation and leads to faster structural failure. Copper (Cu) has the potential substantially improve resistance alloys. In this study, high-entropy alloy (HEA) coatings containing Cu were deposited using DC (Direct Current) magnetron sputtering enhance mechanical properties of various substrates. Two CuCrFeMnNi HEA compositions form bulk alloys PVD (Physical Vapor Deposition) coatings, with 5% 10% Cu, analyzed their microstructural, mechanical, anticorrosive characteristics. Deposition parameters varied select optimal values. Microstructural evaluations SEM-EDS (scanning electron microscopy energy dispersive X-ray spectroscopy), XRD (X-ray diffraction), AFM (atomic force microscopy) revealed uniform, dense good adhesion composed dendritic interdendritic BCC (body-centered cubic) FCC (face centered structures, respectively. Microhardness tests indicated improved samples coated developed HEAs. The exhibited NaCl solution, composition displaying highest polarization lowest rate. These findings suggest that Cu-containing are promising candidates applications requiring enhanced protection.
