Friction-stir-surfacing (FSS) process is an advanced and surpassing technique for surface amendments. The current study investigates the mechanical, metallurgical and corrosion characteristics of Al-Cu-Si (AA2014-T6) alloy-coated over low-carbon steel IS2062 substrate. An investigation was conducted to examine how friction-stir-surfaced (FSS) aluminum alloy coatings correlated with its mechanical, metallurgical, corrosion and other surface properties. Mechanical, metallographic and electrochemical testing methods were employed to evaluate bond quality at interfaced regions which were assessed by optical microscopy (OM), X-ray diffraction analysis (XRD) and scanning electron microscopy (SEM) techniques. The influence of process parameters such as frictional force, rotational speed, and table traverse speed individually denoted as C1-C8 on tensile properties, bending strength, flash width and face diameter of bar was evaluated. The mechanical performance studies stated that the maximum hardness values of 165 +/- 4 HV are observed for sample C8 and a lower hardness of 70 +/- 4 HV is observed for sample C5 combination in the coatings. The corrosion studies revealed that higher values of corrosion rates (0.0111 mm/y) are observed for combination C5, while these values are lower (0.008474 mm/y) for combination C8. All FSS AA2014-T6 alloy samples shown are superior to the standard corrosion rate (0.002638 mm/y) due to fully recrystallized fine grains and not better than base metal substrate due to higher strain hardened (residual) zones. The experimental findings of the current study will be useful for the promising applications transversely several industrial parts, automotive (air-suspensions, brackets, frames), aerospace structural components (fittings, wheels, tanks), marine hulls, pumps, turbine blade reclamation and crack repairs.
