SELF LUBRICATING COMPOSITE ANODIC COATING FOR LIGHTWEIGHT METAL ALLOYS
BOOTH NO : I8
Category : Manufacturing Technologies
Anodizing refers to electrochemical anodic oxide film formation; it is one of the most popular methods to increase wear and corrosion resistance of light alloys, especially under light loads. Anodic films are most commonly applied to protect aluminum (Al) alloys. The main concern is the porous structures of oxide films, which lead to significant flaws at the surface. This surface defect may start to cause problems during sliding that can lead to a high friction coefficient. In this project, we introduced an improvement of mechanical and tribological behavior of oxide coating through the incorporation of graphite and graphene as the reinforcement materials. The effectiveness of formulated solid lubricant additive in the oxide coating can supports the strong request by industry today for machines that use less energy for the same output and have components that last longer in service.
Limited research has been addressed toward the development of self-lubricated coatings containing solid lubricants. One of the main reasons for this is the complexity of embedding solid lubricant inside the matrix of the coating. Poor bonding leads to detachment of particles from the matrix and these act as third-body abrasives and, consequently, increase wear. The comprehensive strategy would require careful attention to prepare graphite or graphene reinforced oxide coating with improved wear resistance and friction property on Al alloy by anodizing method. This project focused on achieving the homogeneous distribution of graphite or graphene in the Al2O3 matrix. Homogeneous distribution of the graphite or graphene in the Al2O3 matrix and make a good bond with Al2O3 matrix could lead to significant improvement in wear resistance as compared to the base alloy.
Self-lubricating coated components are also referred to as maintenance-free or greaseless bearings as they require no relubrication or grease
Many areas of the component parts are difficult to access for service and thus self-lubricating coated components can benefit from components with long service lives
Self-lubricating bearings eliminate the need for maintenance, lowering labor costs, and increase the service life of mechanical component applications
Self-lubricating materials provide cost-effective solutions to various end-users compared to grease or oil
Growth in the automotive industry and increase in demand for self-lubricating materials for the maintenance of machineries in order to increase efficiency and reduce cost are the key factors driving the global self-lubricating materials market
Additionally, increase in focus on quality is estimated to influence manufacturers to opt for quality lubricating materials that provide optimum performance.
Rise in research & development activities in the field of bio-based self-lubricating materials is estimated to create substantial opportunities for manufacturers of self-lubricating materials.
Low cost technology
Our anodizing process works at higher currents and potentials, and requires a shorter processing time namely: a high growth rate as well as more suitable for treating complex geometry samples
Green technology as we used green lubricant additives as graphite and graphene contains only Carbon element
Composite anodic coating technology is not commercially available in Malaysia
To achieve high wear resistance, the industries focused on using conventional hard anodizing (TYPE 3)
