Анотація: (English) This article considers the problem of traditional use of nickel in jewelry production, associated with the risk of allergic reactions, and presents a comprehensive solution based on the development of an innovative nickel-free alloy with gold plating. A review of the literature demonstrates that nickel, used to provide luster and strength to products, can release ions upon skin contact, leading to allergic contact dermatitis. The present study is devoted to the development of a new composition that excludes nickel, while maintaining the necessary mechanical and aesthetic properties, as well as the technology of gold plating with the formation of a protective barrier layer, which ensures the hypoallergenicity of the product. The obtained results, confirmed by X-ray fluorescence analysis (XRF) and certification from “UKRCHIMANALIZ” LLC (2020), indicate the complete absence of nickel and the coating resistance to corrosion, which meets modern regulatory requirements (EN 1811, REACH). The scientific novelty lies in the integration of environmentally friendly materials into jewelry production through the creation of a unique nickel-free alloy capable of meeting the requirements of safety, aesthetics and functionality.
