Investigation of mechanical properties on nano cuprous oxide coated/uncoated spur gear

Abstract

Abstract Metals and their alloys have been widely used in all aspects of science and engineering. However the science of nanotechnology is driving newer demands and requirements for better performance of existing materials and also at a higher level of precision. This is naturally presenting complicated demands on the surface of these metals with a need for surface modification. In the present scenario it is noteworthy that nano scaled particle coatings enhances the mechanical properties in the metals rather than the macro or micro sized particles. Hence an attempt was made to characterize the mechanical properties of cuprous oxide nano particles coated spur gear (Mild Steel). The mechanical properties such as tensile, hardness and corrosion (salt spray) were experimentally investigated at ambient condition. A deep compression had been made between the coated and uncoated gear. The results reveal that the coated gear shows better performance compared with uncoated gears.
