Abstract
Centrifugal pumps are prevalent for many different applications in the industrial or other sectors. The paper reviews the literature available on
the improvement of efficiency of centrifugal pump through improvement in performance of pump shaft (AISI 316L stainless steel). The paper
discusses the available material of performance improvement through amelioration of tribological characteristics of pump shaft and mainly
focuses on the abrasive wear resistance of AISI 316L stainless steel. In order to improve the abrasive wear resistance of stainless steel
components, carbide-hardened surfaces were produced on AISI 316L austenitic stainless steel by salt bath nitriding. Nitriding of AISI 316L
austenitic stainless steel was carried out at high temperature (580°C) for 10 h. The microstructures, abrasive wear resistance, as well as its
surface hardness, were investigated using optical microscopy, tribometer tester and microhardness tester. The results confirmed that salt bath
nitriding was effective in improving the abrasive wear resistance.
