Abstract—In a textile mill the spinning machine's ring frame comprises of a ring and a traveller. The yarn is twisted with the help of a traveller and is winded on the bobbin with the dual support of a ring and the traveller. The traveller is dragged along behind by the spindle even though it doesn’t have a drive on its own. During winding the centrifugal force generates high contact pressure between the ring and the traveller. This pressure results in the internal surface degradation of the ring which further affects its working life. The main aim of this study was to augment the working life of the ring in order to depreciate the idle time required to restore the rings on the spindle repeatedly during spinning. The objective was accomplished by the means of thermal spray coatings, where the effect of the coatings on the ambit of the wear and wear characteristics of the rings were inspected. In this study the plasma sprayed coatings, namely Cr3C2NiCr was analyzed on E52100 of the ring. ATSMG99 standards were used for performing wear tests on Pin-on-Disc for both the uncoated and coated samples of E52100. The wear behavior of the coated as well as uncoated bearing alloy steel is interpreted with the result of wear data generated. The result exhibit that Cr3C2NiCr has been profitably deposited on E52100 grade of bearing alloy steel by plasma spray process. In comparison to bare E52100 the coated E52100 have shown considerably less wear loss. The accruing volume loss for plasma sprayed coatings increases with the increase in load. The Cr3C2NiCr coating has sustained minimum wear. The Cr3C2NiCr- E52100 coating-substrate combination has shown minimum wear.
