Abstract : Since G. Bird introduced Nickel electrodeposition coating in 1837, it has remained a focal point of research. Over the past few decades, attention has shifted towards its distinctive applications and properties in engineering. Electroplated nickel coatings offer numerous advantages over conventional electrolyte coatings, especially in terms of their excellent tribological properties, leading to widespread use in industries such as chemical, automotive, aerospace, and electrical. To further enhance these properties, researchers have incorporated second phase particles like SiC, ZrO2, B4C, TiO2, Al2O3, Si3N4, CeO2, between others, into the electrodeposition process. Studies have demonstrated that the addition of these particles leads to improvements in tribological characteristics. As industries continue to seek new coating materials with superior tribological properties for various applications, this article reviews the tribological advantages of different electrodeposited nickel and chromium (Ni-Cr) nano coatings, considering factors such as bath types and structure.
