Developments on friction surfaced coatings for corrosion, wear-resistant and composite

Friction surfacing is the most recent technology applied in surface engineering for developing surface materials. It is a solid-state technique employed to coat one material over another material in order to reconstruct the worn-out parts, to enhance protection from ware and corrosion, to develop mechanical features and composite materials.This is an environmentally-safe process in which a consumable rod is deformed plastically and forms a deposit of viscoelastic material over the substrate. The thickness and properties of the layer can be controlled by the rotational speed, axial downwards force, horizontal motion, time and tilt angle. Different materials have been taken in friction surfacing for deposition. The friction surfaced coating is also modified in different way according to requirement. Friction surfacing has been significantly applied to industrial applications. This paper reviews thoroughly the properties and microstructure of friction surfaced coating using different operating parameters and processes, focusing alternative technology on future research.
