Wear behaviour of different nano particles coating on Al6061 substrate
ABSTRACT The tribological behaviour of Ni-based composite coatings on Al6061 substrate with secondary phase hard oxide particles like ZrO2, TiO2, and Al2O3 at different elevated temperature conditions was compared. The composite coatings with different reinforcement of nano particles were characterized by scanning electron microscopy and X-ray diffraction technique. The higher microhardness value is reported for the Ni coating with TiO2 particles and Al2O3 particles. At higher temperature limits of 120°C and 140°C Ni–ZrO2 coatings have found better specific wear rate. The Ni–Al2O3–TiO2–ZrO2 composite coating fails to achieve better properties due to higher agglomeration of the particles and dendrite growth. The Ni–Al2O3 coating showed steady wear behaviour at different temperature limits. The coefficient of friction values is found nearly similar for all the type coatings at 40°C and 120°C.
期刊介绍:
Surface Engineering provides a forum for the publication of refereed material on both the theory and practice of this important enabling technology, embracing science, technology and engineering. Coverage includes design, surface modification technologies and process control, and the characterisation and properties of the final system or component, including quality control and non-destructive examination.
