Decorative Coatings and Metals in Jewellery and Art Products

Abstract

The article considers the classification of precious and non-precious alloys used in the manufacture of jewellery and art articles. Alloys are considered from the point of view of necessity of using protective and decorative coatings both for protection from environmental impact during operation of articles and colour surface decoration. A diverse nomenclature of various metallic, non-metallic and conversion coatings formed by different technological methods is shown. It is shown that the use of a certain coating is largely determined by the designer at the stage of creating a rendering of the product. Necessity to take into account the colouristic characteristics of alloys and coatings at the design stage and the existence of an inseparable connection between the product design, materials used, technologies of their shaping and decoration is pointed.
