Popis: | The main objective of this work is to develop a plasma coated aluminium alloy brake disc reinforced with Silicon Carbide and Graphite on the surface. The coated brake disc specimen is characterized and is validated for their braking time in single seater (All-terrain vehicle) ATV vehicle in static condition. Plasma spraying was carried out using 40 kW atmospheric plasma spray system. Input DC power to the plasma torch was varied from 10 kW to 20 kW by controlling the arc current and voltage. Aluminium alloy disc coated with silicon carbide and graphite were investigated for its hardness, wear rate and the braking time. Micro hardness of plasma sprayed samples was tested. The disc was characterized using X-Ray diffraction technique (XRD) to identify the compounds. Scanning electron microscope is used to study the surface and interface morphologies of the coatings. Line and area Electron Dispersive Spectroscopy (EDS) were carried out to determine the constituents present in the surface of the composite disc. |
