Abstract

3Cr13 stainless steel (SS), commonly applied to marine engineering components such as bearings and drive shafts, is damaged by tribocorrosion. For improving the resistance of tribocorrosion, the Cu₅₅Zr₂₅Ti₁₅Ni₅ glassy composite coating is prepared via high-velocity air-fuel (HVAF) spraying technology on 3Cr13 SS, and the tribocorrosion experiment of the coating is investigated using friction and wear tester. The coating exhibits a multiphase structure, comprising amorphous-nanocrystalline region and oxide phase consisting of TiO₂ and t-ZrO₂, of which the amorphous-nanocrystalline phase accounts for about 53 %. The nanomechanical properties and the corrosion properties are investigated. The analysis of the tribocorrosion system (counter-balls, post-tribocorrosion solution, and wear tracks) is carried out using 3D scanner, inductively coupled plasma mass spectrometer (ICP-MS) and scanning electron microscope (SEM). Abrasive wear and fatigue wear mainly occur in the coating during tribocorrosion, and adhesive wear and chemical reaction wear are slight. As the load increases, tribo-film is formed on the surface of the coating and the wear rate decreases dramatically, due to the suppression of abrasive wear. The wear rate of the coating is only half of that of 3Cr13 SS at the load of 30N.

期刊介绍： This journal is a platform for publishing innovative research and overviews for advancing our understanding of the structure, property, and functionality of complex metallic alloys, including intermetallics, metallic glasses, and high entropy alloys. The journal reports the science and engineering of metallic materials in the following aspects: Theories and experiments which address the relationship between property and structure in all length scales. Physical modeling and numerical simulations which provide a comprehensive understanding of experimental observations. Stimulated methodologies to characterize the structure and chemistry of materials that correlate the properties. Technological applications resulting from the understanding of property-structure relationship in materials. Novel and cutting-edge results warranting rapid communication. The journal also publishes special issues on selected topics and overviews by invitation only.
