Nano-Guardians: Smart coatings resilience in extreme environments

The objective of this work is to analyse the tribological behaviour and durability of new generation of Hard Coatings known as Nano-Guardians in harsh environment. Four different types of coatings were examined, and it was discovered that all of the coatings’ ingredients differed from one another and comprised such substances as graphene oxide, titanium dioxide, polyurethane, ceramic nanoparticles, and quantum dots. These are known as NanoArmor, TitanShield, PolyResilient and QuantumGuard. During the controlled exposure test wear rates were high due to recreation of such tough conditions. For instance, NanoArmor wear rate was measured at 0.002 mm3/Nm when tested under conditions of controlled exposure. Functional checks confirmed mechanical endurance of the coatings and had indicated that TitanShield had better adhesion and abrasive stress resistance. Some observed characteristics were revealed through the performance assessments. For instance, TitanShield outperformed the NanoArmor by at least twenty percent in terms of wear rate, while QuantumGuard was relatively intermediate in terms of this parameter as well as flexibility. The work reveals the tribomechanical interplay of Nano-Guardians that contributes to the development of smart coatings for multiple applications in industry. These consideration can be based on real data and percentage changes.
