Automotive plastics are heterogeneous and complex mixtures of various plastics incorporated with significant amounts of additives and fillers. Automotive shredded residue (ASR) waste plastics are difficult to recycle and hence contribute significantly to environmental problems. In this study, a sustainable approach to fabricate protective nanoscale TiN thin film on a metal surface by using automotive waste plastics as titanium and carbon sources is investigated. The synthesis of nanoscale thin film of titanium nitride on steel substrate was carried out by using carbothermal reduction and nitridation reaction in a nitrogen atmosphere. The formation of TiN nanofilm on steel substrate was confirmed by XPS, XRD, and EDS techniques. The TiN film was characterized by HRTEM, and thickness was found to be in the range of 18 nm. The uniform and highly crystalline TiN thin film could provide good oxidation resistance to steel substrate. This innovative approach of using automotive waste plastics as titanium and red...
