"Carbon coatings were reported in 1954 and exhibit graphite-like behaviours since diamond-like carbon (DLC) coatings were reported around 1970. DLC coatings grasped rapid recognition in the industry and were widely adopted for mechanical applications as DLC coatings exhibit high hardness, lower friction coefficient and excellent anti-wear properties. DLC coatings have progressed through a range of deposition techniques like physical vapor deposition, plasma-enhanced chemical vapor deposition etc.; coating architectures such as monolayer, multilayer, doped; nanocrystalline, amorphous or granular morphologies; and have been used for a wider range of industrial applications including automotive, mechanical components and cutting tools, healthcare products, renewable energy, computing and electronics, plastics, textiles sectors etc."--
