Iranian Firm Uses PVD Coating to Produce Beautiful Dining Utensils
A gold-colored titanium nitride (TiN) coating is one of the most widely used nano-coatings for decorative and industrial surfaces, which is applied to metal surfaces through PVD (physical vapor deposition) technology. By creating nanoscale structures, this technology not only gives the utensils a beautiful appearance, but also increases their resistance to scratches, corrosion, oxidation and discoloration.
Compared to older methods like electroplating or metallic and non-metallic coatings, PVD coating provides advantages like high adhesion, surface uniformity, the absence of toxic materials, and the ability to precisely control thickness.
Tak Steel Paya company succeeded in launching a TiN coating system by using the PVD method. This coating is applied to 18/10 stainless steel dishes using common PVD methods like Arc-PVD and sputtering. 18/10 steel, with a combination of 18% chromium and 10% nickel, is one of the most resistant and standard alloys used in the food industry. Chromium prevents rusting, and nickel provides shine and stability to the surface.
In relevant remarks in 2023, the managing-director of Ara Seram company had underlined the advantages of using nanoparticles in materials produced by PVD method.
Engineer Farhad Qaffari stressed the effectiveness of using nanotechnology in improving the good features of products.
“By using methods like PVD, we make new products with nano properties, which, compared to similar ordinary products, enjoy features like environmental compatibility free-from-pollution properties, increased resistance to corrosion, resistance to wear, creation of different colors, and cost reduction due to quality and longevity,” he added.
Several Iranian nanotechnology companies have succeeded in development of physical vapor deposition (PVD) system, enabling the application of golden ceramic compound with a variety of thicknesses on different substrates.
‘Pars PVD’, ‘Tolerance Atris’, ‘Iran Bronze Steel’, ‘Kimiyae Saadat Sanat Modern’, ‘Ara Ceram’, ‘Noor Mehr Hoda’ and ‘Negar Gostar Javid’ companies have made the nano-based product.
