Graphene-Based and Spray Deposition Techniques

---

Coatings based on graphene are transforming the coating industry, providing lightweight, highly conductive, and ultra-strong films. These coatings are being incorporated into flexible electronics, aerospace parts, and protective military applications because of their outstanding thermal, electrical, and mechanical characteristics. The demand for wear-resistant and anti-corrosion coatings is increasing, especially in defence, automotive, and renewable energy industries.

Thermal spray and cold spray deposition methods, among others, are frequently employed for biomedical coatings, automotive anti-corrosion applications, and self-cleaning surface developments. Thermal spraying techniques apply coatings in a molten or semi-molten state, making them particularly suitable for wear-resistant coatings on turbine blades and industrial equipment. Cold spray techniques, utilizing high-velocity particle deposition, are increasingly employed for applications such as electronic shielding, medical implants, and aerospace uses.

A growing emphasis is being placed on the sustainability of coating technologies, driven by innovations in water-based coatings, low-energy plasma treatments, and eco-friendly spray techniques that minimize environmental impact. The integration of artificial intelligence-driven modelling for spray coatings is predicted to optimize material efficiency by minimizing waste and improving durability and functionality. The ongoing advancements in graphene-enhanced and bio-based coatings will propel the development of next-generation protective and functional coatings for smart materials, renewable energy, and high-performance industrial applications.
