An investigation of abrasive wear and corrosion behavior of surface repair of gray cast iron by SMAW

Journal of Materials Research and Technology, 2017
In this work, improving the abrasion–corrosion behavior of gray cast iron used in centrifugal pumps was studied. These pumps are usually made of gray cast iron (BS:1452Gr220) and are repaired by Shielded Metal Arc Welding (SMAW).
