Friction and wear have been shown to be a source of power loss and an increase in manufacturing costs in industry. Many researchers created cutting-edge methods for reducing friction and wear in two sliding components. Lubricants, both liquid and solid, are utilized to improve the working qualities of the materials. The advancement of nanotechnology has provided manufacturers some relief since nano coatings are more dependable at reducing friction and wear. In this study, an attempt is made to deposit Al2O3 and TiO2 in mono-layered and multi-striped coatings, and an interpretation is made to assess the coated disc’s tribological achievement using a pin-on-disc apparatus. The grooves necessary for coating are created using an Electric Discharge Machine (EDM), and the grooved disc is coated using a Physical Vapor Deposition (PVD) machine. Tribological characteristics like as wear, friction, and force are investigated. The creative solutions reveal that the force of friction and coefficient are lowered as a consequence of the use of nano coatings, although wear rate is enhanced in some trials due to the unpleasant conditions.
