Abstract
Friction surfacing is a candidate process for depositing corrosion and wear resistant coatings Being a solidstate process it offers several advantages over conventional fusion welding based surfacing process In the current work martensitic stainless steel AISI 410 was friction surfaced over mild steel substrates Coating microstructures were characterized using light microscopy scanning electron microscopy and Xray diffraction Coatings in asdeposited condition exhibited a fully martensitic microstructure and were found to be quite hard with an average hardness of 460 HV Bend and shear tests indicated excellent coating/substrate bonding Overall the current work shows that martensitic stainless steel AISI 410 can be satisfactorily friction surfaced on mild steel
