Experimental analysis of Fracture Toughness of EN9 and EN31 Steel under double layer of electroplating materials with different varied thickness

Abstract

Abstract With the advent of technology, there is a need to invent newer plating to improve the strength of the material. In this paper, two materials namely Steel Grades EN9 and EN 31 are considered. These materials are having quite a good industrial applications and are being used in many machine parts manufacture. Some of the widely used applications are in the manufacture of Crank shafts, Cylinders, Gears, Sprockets, aerospace parts and body of the ships and automobile parts mainly its surfaces which require high impact resistance and also wear resistance for increased life of the components. The non-electro plated materials are also having the property of higher abrasion resistance. In this paper, the preparation of the specimen, electro plating techniques adopted for getting varied thickness and their critical characteristics in improving the property of the material are discussed further, a statistical model is proposed to obtain the bench mark for its effective implementation of these materials for its industrial use.
