A Critical Analysis of Cold Spray Coatings and its Tribological Performances
Abstract: Coatings are utilized for temperature barrier, protection against corrosion and wear etc. Cold spray is a solid-state processing method that is unique among thermal deposition procedures since it deposits particles at temperatures below their melting point. This technology does not involve particle melting, hence retaining the original properties of the materials. Increased coating strength is achieved by retaining of feedstock powder microstructures and characteristics, which prevents oxide formation and other …

Engineering Perspectives: Thermal and Structural Examination of Disc Brakes for Light Vehicles
Abstract: The procedure of braking transforms the kinetic energy of a car into mechanical energy that needs to be released as heat. High temperatures may result from the frictional heat produced at the disc and pad interface during the braking phase. Frictional heat produced on the rotor surface can contribute to an excessive rise in temperature, which can have unfavorable effects including premature wear, brake fluid vaporization (BFV), thermally excited vibrations …
