This paper presents an experimental study of both wear and corrosion performance of Ni-Graphene nano composite coatings at simulated industrial conditions. It is essential to understand the performance of Ni-Graphene nano composite coating when subject to tribo-corrosion environments to predict service life and enhance durability of industrial equipment. During this research Tribo-corrosion performance of Ni-Graphene coating deposited by electrodeposition technique is evaluated and the main mechanisms associated with their degradation under combined wear and corrosion are highlighted. The effects of various parameters such as: coating composition, microstructure, defect level, adhesion, cohesion and substrate properties are discussed. These parameters are seen as some of the most critical attributes in coating performance when subjected to tribo-corrosion contacts. Interactions between wear and corrosion mechanisms are significant in terms of their influences on the durability of these coatings. These mechanisms are studied in detailed through advanced experimental methods along with state-of-the-art predictive modelling techniques. These modelling techniques are useful tools for the design and development of nano coatings and to predict their performance under varying industrial applications.
