Abstract

Magnesium alloys are easily exposed to wear and corrosion during service life, hindering their applications. Herein, the Ti-Ni-Cu coatings were designed. Thermal-mechanical simulation of laser cladding on magnesium alloy surface was performed for exploring the optimal cladding parameters. Form the simulation results, laser power of 1200 W, scanning speed of 20 mm/s and spot diameter of 3 mm were applied. A series of characterizations were performed to study the microstructure, corrosion and wear properties of the coating. The results indicated Ni_52.5Ti_33.5Cu₁₄ coating presented the comprehensively enhanced wear resistance than the substrate. Specifically, an increase in coatings’ microhardness by a factor of 6 over substrate was achieved. Besides, the I_corr was one order of magnitude lower than that of the substrate.

期刊介绍： Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
