Abstract: The aspects of investigation on surface characterisation and role of material for various applications of petroleum, gas refineries, marine, aerospace, etc. have spurred in this era. The usefulness of surface protection techniques, materials, their performances and characteristics for particular medium is important to study, as it is vital to employ a specific required material for particular application. Considering these features, this manuscript presents the overview of plasma transferred arc welding technique used for the surfacing of parts. The main aim is to focus the investigations carried out from last decade based on tribo-corrosion performance of overlay surfaces and their key observations. In addition, the material combination, effects of process parameters, cause and effect diagram, microstructural benefits, common advantages and drawbacks associated with the technique are also presented. This will be beneficial to find out the main targeting areas by establishing a theoretical and technical bias for new research and industrial people.

Keywords: surface modification; plasma transferred arc welding; overlay; erosion-corrosion; wear; abrasion.
