2. If there is residual RCF after grinding, that could be the area of growth depending on the Friction Modifier used. 3. When using an HH material there seems to be a max depth of crack propagation. 4. The HH rail did not have the severe RCF propagation as that exhibited by the rails used in the previous study (WRI 2014) 5.

Grinding is a machining process improving the surface finish of the job and producing small chips. The tool used for this process is the grinding wheel. It is a cutting tool in which millions of microscopic abrasive grains are bond together. Here, each abrasive grain acts like a spiky tool. As shown in the image, the abrasive grains are held ...
