Electroless nickel alloy coatings provide a hard, wear-resistant, and corrosion-resistant surface. Thus, the present study aims to investigate the wear, corrosion, and tribocorrosion behaviors of monolayer and duplex coatings with nickel-boron (Ni-B) and nickel-phospore (Ni-P) on 316L steel in comparison with 316L steel in dry sliding and 0.9 wt% NaCl solution environments. It is determined that the coatings have a mixture of crystal and amorphous structures, the interfaces on the 316L are uniform, and the compatibility between the layers is good. The Ni-B, Ni-P/Ni-B, and Ni-B/Ni-P coatings are 2.3, 2.06, and 1.6 times as hard as the 316L, respectively. The wear rates of Ni-B, Ni-P/Ni-B, and Ni-B/Ni-P coatings show decrease by 99.3%, 92.5%, and 99.1% in the dry-sliding condition and by 98.5%, 30.1%, and 19.1% in the tribocorrosion condition compared with that of 316L, respectively. It is observed that the monolayer Ni-B coating exhibits superior hardness, a higher contact angle, low electrical conductivity, and better tribological performance in both dry sliding and tribocorrosion conditions compared to the 316L and duplex coatings.eninfo:eu-repo/semantics/closedAccessTribocorrosion behaviorSliding wearNickelAlloyHardnessProtectionResistanceCompositeAisi 316lDry sliding wearElectroless coatingElectrolytic corrosionTribocorrosionScience & technologyTechnologyMaterials science, multidisciplinaryMaterials scienceArticle000949295300001251010.1002/adem.202201501
