Synthesis and Characterization of Wear and Corrosion Resistant Ni-Doped Al2O3 Nanocomposite Ceramic Coatings by Sol-Gel Method

Abstract

Cp-Ti is frequently used in biomedical applications because of its good corrosion and high biocompatible properties. However, its poor wear resistance limits its use in some applications. Therefore, this study aims to improve its wear and corrosion resistance by producing Ni-doped Al2O3 nanocomposite coatings on Cp-Ti. In order to achieve this goal, undoped Al2O3 and Ni-doped Al(2)O(3 )nanocomposite ceramic coatings were produced on Cp-Ti samples at two different rotational speeds by the spin coating process, which is a sol-gel method. Afterward, their structural and morphological features were examined by XRD, SEM, Raman, and 3D surface profilometer. Reciprocating wear tests and electrochemical investigations were performed to determine their wear and corrosion properties.
