Particulate preplaced TIG melted surface layer of duplex stainless steel

Despite their excellence qualities, DSS shows decrease in performance under aggressive environment. Under this condition, DSS is vulnerable to failure due to combined action of wear and corrosion. Therefore, the main aim of this project is to perform surface modification and study the effect of proc...
