| Abstract Scope |
Globally, a fifth of energy generated annually (~100 million terajoule) is needed to overcome friction and wear. This accounts to 1 – 4% of the gross domestic product of industrialized economies. Therefore, there is the need to minimize wear and friction. This is achievable by depositing two-dimensional materials, such as graphene and its variance on metallic surfaces. This paper presents results of experimental and theoretical/computational study of macroscale superlubricity of carbon coated metallic surfaces. Carbon nano crystals with graphene signatures were deposited on 1045 steel, Ni invar, CP Ti and Ti6Al4V alloys. The deposition was achieved through a novel low-cost high temperature biowaste treatment prior to wear and friction experiments. The carbon nano crystal coatings deformed to graphene nano composite film with varying orientation and sizes and covered the wear tracks during the wear test. The implications of these results on circular economy and reduction of carbon footprint are elucidated. |
