Sliding Wear Analysis on A390 Aluminium Nanocoated with Sol-Gel–Synthesized Particles for Bearing

Abstract

ABSTRACT Nano means small but of high potency, and emerging with large applications piercing through all the discipline of knowledge, leading to industrial and technological growth. In other words, nano-sized structure needs to be magnified over 10 million times before we can easily appreciate its fine detail with the naked eye. Nanotechnology is already having its impact on products as diverse as novel foods, medical devices, chemical coatings, personal health testing kits, sensors for security systems, water purification units for manned space craft, displays for hand-held computer games, and high-resolution cinema screens. Nanotechnology is expected to have an impact on nearly every industry. Nanotechnology can overcome the negative impact of wear and friction, enhance the life of the component, and improve the efficiency. The aim of this work is to reduce the size of chromium nitrate particles to the order of nano (10−9m) size using sol-gel method, analyze the surface topography of the steel and alumi...
