Optimization of Stellite Defect in Manufacturing of Engine Valves: A Review
Abstract: Intake and exhaust valves are the important components of an engine valves which are used to control flow and replacement of fuel gases inside the cylinder. This work mainly deals with defect known as stellite defect in different sizes of engine valves; and methodology adopted to prevent valve from stellite defect. Valve base material is low alloy steel (AISI 4140) and upper surface of engine valve is generally hard faced …

Implications of WC–cobalt Composed Forms Matrix
Abstract: This article summarizes some forms of tungsten carbide in metals under composition. Accumulated ceramic and metal powders produce cement carbide (CC). Systems in these categories are used to manufacture resistive equipment. Cementation method of tungsten carbide is a metallic manner. CC mine drills are applied for any corrosion resistant purposes. Common matrix metals are Co, Ni, Cu, Al, etc. The performance fault from heat-treated assisted oxidation was assessed by the …
