High-strength and corrosion-resistant black titanium clock ornament and production process thereof

Abstract

The invention discloses a high-strength and corrosion-resistant black titanium clock ornament and a production process thereof. The clock ornament comprises an outer frame made of high-strength and corrosion-resistant black titanium metal, and ornament lines are directly arranged on the outer frame. The clock ornament has the natural and black surface, requires no electroplating, cannot fade for along time, has very high stability, cannot be scratched or damaged when impacted by hard objects, can resist sweat and other corrosive substances and can always keep higher gloss surface effect. Theproduction process is based on a black titanium technology, a titanium material is treated in 7 steps including titanium alloy solution preparation, casting, hot rolling, intermediate annealing, coldrolling and finish rolling, continuous straightening and withdrawal and finish machining, so that a black surface layer is formed on the surface of a titanium alloy, a mirror effect is obtained aftercold rolling and finish rolling of the black surface, finally, the density of particle sizes of crystals on the surfaces of the titanium metal strips is larger than that of the middle through continuous straightening and withdrawal, the titanium metal becomes harder, and the corrosion resistance and scratch resistance of the black titanium are greatly improved.

Description

technical field [0001] The invention relates to the technology in the field of watches, in particular to a high-strength anti-corrosion black titanium watch ornament and a manufacturing process thereof. Background technique [0002] Titanium is more expensive than other watch-making metals, so it is mainly used in relatively high-end products, such as structural parts of rockets, missiles and high-speed aircraft, and now famous Swiss watches are also gradually used. [0003] With the rapid development of today's society, in terms of watch design, more designers choose to use black elements to highlight the cool style. Among the many watch case manufacturing materials, titanium is favored as a mid-to-high-end material, while traditional methods The main reason for making titanium black is to form a black electroplating layer on the surface of the titanium material by electroplating, but the electroplating layer is very unstable, and the electroplating process often produces a...

[0003] With the rapid development of today's society, in terms of watch design, more designers choose to use black elements to highlight the cool style. Among the many watch case manufacturing materials, titanium is favored as a mid-to-high-end material, while traditional methods The main reason for making titanium black is to form a black electroplating layer on the surface of the titanium material by electroplating, but the electroplating layer is very unstable, and the electroplating process often produces a lot of pollution, such as waste gas and waste water discharge, and greatly increases the cost of enterprises. cost, reducing business efficiency

[0004] The survey found that the corrosion resistance of the traditional method of electroplating a black surface layer on the surface of titanium materials can no longer meet the requirements of the company's high standards and high-quality products
