Aluminum reinforcement by gas tungsten arc welding

open access: yesScience and Engineering of Composite Materials, 2012
AbstractAluminum is a light metal and is widely used in a variety of industries. Aluminum-silicon has good casting properties but does not offer any suitable tribological properties. Therefore, in this study surface composite coating was performed by the gas tungsten arc welding (GTAW) process, which increased hardness up to 34 HV, which is nearly two ...
