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 …

Metal Surface Coating Through Welding Processes
Abstract: The adversity of service conditions limits the service life of components. The replacement cost of the components is extremely high. Surfacing technique offers benefits in reducing materials costs and, in salvage applications, enables an expensive or difficult-to-replace part to be reclaimed and restored to operation with minimum of downtime. Industries involved in surfacing operations use various fusion welding especially arc welding processes. These operations demand high deposition rates but at …
