Chrome coatings provide good wear resistance and are cheap. However, it causes health and environmental hazards due to the presence of hexavalent chromium. A few of the alternatives which are available in the industry are thermal spray, in particular high-velocity oxy-fuel (HVOF) which is preferred due to its high strength and wear resistance, relatively low cost, and fast turnaround time. Other emerging processes include electroless nickel composite plating, which can deposit uniformly diamond-composite coatings and are not restricted to line-of-sight geometries. Other emerging techniques include explosive bonding that could be used to make stainless-steel or titanium coatings. Another method is plasma vapor deposition (PVD); which can make thin, high quality coatings for less cost; in many cases; than even decorative chrome.
The Advanced Coating and Surface Technology TechVision Opportunity Engine (TOE) provides intelligence on technologies, products, processes, applications and strategic insights on various coatings across industries. This encompasses protective and functional coatings such as antimicrobial coatings, food coatings, energy-saving coatings, smart glazing, hydrophilic, hydrophobic and super hydrophobic coatings, corrosion protection coatings, barrier coatings and paints.
The Materials and Coatings cluster tracks research & innovation trends and developments across specialty chemicals, plastics, polymers, chemicals, bio-chemicals, metals, coatings, thin films, surface treatments, composites, alloys, oil and gas, fuel additives, fibers and several other related technologies and its impact and application across industries.
