ABSTRACT

The main aim of present work is to enhance effectively the working life of boron steel (medium carbon steel, 22BMn5) having application in agricultural implements. Process was carried out by using a protective layer i.e. providing a coating. Coating provided had the basic properties like high density and high wear resistance. Tungsten Carbide with 12% Cobalt (WC-Co) coating powder was selected, it shows improved wear resistance. Powder was mixed with cerium oxide, (5% and 10%) using ball milling with powder to ball ratio of 1:1 for time interval of 1 hour. Study is carried out in order to have knowledge about its phase and micro-structural characteristics and phase. Specimens were fabricated and wear test was carried out using pin-on-disc test rig. Wear test was carried out under three different load conditions with 7 cycles (to completely understand the wear behavior/pattern). SEM/EDAX and XRD analysis of worn out surface was performed, and results depicted that when lubrication is done with low value of applied load, powder with high percentage of cerium oxide shows the best result i.e. practically negligible wear loss.

Keywords: D-Gun, Pin-on-disc Test Rig, XRD, SEM/EDAX
