“…A surface hardness of around 800 HV was achieved via heat treatment at 500 °C for 24 h due to the diffusion of nickel in the 7075 aluminium substrate and formation of Al3Ni2 intermetallic phase. This value reported to be around 670 HV by heat treatment at 550 °C for 24 h due to the diffusion of aluminum toward the surface [18,19].…”

In this study, AA2024 aluminum alloy specimens were electroplated with almost uniform nickel coating with an average thickness of 5 μm. The coated materials were then heat treated in an argon atmosphere at 450, 500 and 550 °C for 30, 60, 90, and 120 min, in order to investigate possible diffusion and formation of intermetallic compounds like Al 3 Ni and Al 3 Ni2 at the interface of the treated specimens. The fabricated layers were characterized by using scanning electron microscope (SEM) equipped with energy dispersive spectroscopy (EDS) analyzer, and x-ray diffraction (XRD) technique. XRD pattern of the electrodeposited materials indicated formation of semi-crystalline nickel coating. In addition, based on the XRD and SEM studies, intermetallic compounds began to form at 450, 500, and 550 °C after 120, 60, and 60 min, respectively. Polarization test were also carried out to study the corrosion behaviors of the coatings. The results indicated that heat treatment deteriorates the corrosion resistance of the coatings. Formation of intermetallic compounds increased the susceptibility to corrosion due to the increase in the formation of localized microcells.

“…The process is widely used because of its uniform coating, good decoration, environmental protection and ability to improve the corrosion resistance, electrical conductivity and lubrication of products. Y. Shajari [83] prepared the nanostructure of Ni-B coating on the surface of nibral alloy, a marine propeller material, and the surface hardness increased from 410 to 788 and 1365 Vickers hardness. The coating and heat treatment improved the wear resistance.…”

As the demand for the development and utilization of marine resources continues to strengthen, the service requirements for advanced marine equipment are rapidly increasing. Surface protection technology has become an important way of solving the tribological problems of extreme operating conditions and improving the safety performance of equipment by imparting certain special properties to the surface of the material through physical, chemical or mechanical processes to enhance the ability of the material to withstand external environmental factors. Combined with the extremely complex characteristics of the marine environment, this paper describes the commonly used surface protection technologies for metal materials in the marine environment. Research on surface texture was summarized under different surface reshaping technologies, as well as processes and coating materials under different surface modification technologies. Combined with the existing research progress and development trends of marine metallic materials, the surfaces of metal materials under the marine environment protection technology foreground are prospected and provide a reference for the improvement of equipment performance in extreme marine environments.
