Technical Field

The invention relates to the technical field of personal ornaments, in particular to a preparation method of a personal ornament with a titanium nitride hard coating.

Background

The origin of the ornaments, originally because of the shielding body, with the continuous development of the living level and the creativity of people, begins to be converted to the decoration part, and derives various decorations mainly based on the decoration. The ornaments are used for decoration and wearing, some ornaments can play roles of fragrance, cleanness, beautification and the like, good ornaments can enable a wearer to feel new and relaxed, a plurality of ornament boutiques on the street increasingly pay attention to the market of the ornaments, and the ornaments can not be separated from the ornaments in home decoration, birthday gifts, friends parties, men and women, and the like. The consumption trend of the ornament industry is as follows: the ornament industry is a new industry which is formed by separating and integrating the industries of jewelry and artworks gifts. Ornaments are used as growth points of new economy, and developed countries gradually mature. All grades of exclusive shops and point-of-sale chess cloth; various styles and various levels of products fully meet the increasing market demand. In China, the industry is still in the early development stage. With the leap development of social economy and culture, people step into a well-off type from a full-warm type, advocate humanity and fashion, continuously shape personality and charm, and become the pursuit of people.
