a) For each of the worn surface describes below in i) and ii), identify the wear phenomenon, describe the wear mechanism (s) that produced the surface, justifying your choice and suggest of reducing the observed wear. (i) Occurs when a material is displaced to the side, away from the wear particles, resulting in the formation of grooves that do not involve direct material removal. Instead, the displaced material forms ridges adjacent to grooves, which may be removed by subsequent passage of hard particles. (ii) Surface wear causes metal to unintentionally engage with another metal in contact. This phenomenon can result in separating metal pieces from the original component. This process is relatively rapid and once initiated can lead to component failure with subsequent operating cycles
