Abstract
Wear brings about drastic fallout in metallic components during their application. It is established that hardfacing process has substantially matured over the recent times. To start with, Stainless steel 410 L is hardfaced over the face of low carbon steel IS-2062 valve seat rings by plasma transferred arc hardfaced process. The main and interaction effects of Plasma Transferred Arc hardfaced variables for stainless steel were obtained. These investigations were based on a design matrix of five factors, five level factorial method. The Regression analysis was tested for scrutinizing the adequacy. The percentage dilution was optimized. The conformity test was conducted and the optimized results were verified, with the percentage of error being calculated. The impact factors on the dry sliding wear resistance of Stainless Steel 410 L alloy was investigated under conditions leading to an obdurate metallic wear condition of the hard facing alloy. Mathematical model was developed relating the wear and the main factors, such as, normal load, Disc Speed, track radius. The Optimized wear model was obtained for minimizing the wear rate. Mathematical models relating wear testing parameters to wear and coefficient of friction were developed. The developed mathematical model can be used to assess the wear and the wear was found to increase.
