Embodiment Construction

[0007] Below in conjunction with embodiment the present invention is described in detail:

[0008] Implementation example, add the metal tantalum raw material into the ball mill and mix 40-90% of the ground metal tantalum powder Tac and 9-59% of the metal nickel powder in proportion; in order to mix the powder evenly and increase the adhesion, so that the mold can be fixed Molding, add 1% binder to the mixture and then mix the mixture and mix it evenly, then pour the mixture into the mold for shaping, then degrease, and finally sinter under pressure protection and pressure, in order to improve the sintering The effect is to increase the bonding of tantalum and nickel, and control the temperature of sintering and setting at 1400°C. In the above examples, due to the addition of 40-90% of tantalum powder mixed with corresponding nickel powder in different proportions, the final sintered ring products have differences in physical properties such as hardness, bending resistance, an...

Abstract

The invention relates to a novel material finger ring and a manufacturing method thereof. The novel material finger ring is mainly formed by mixing tantalum and nickel. The compositions in weight percentage of the novel material finger ring are 40 to 90 percent of the tantalum and 9 to 59 percent of the nickel. The compositions are uniformly mixed when 1 percent of adhesive is added; a finger ring blank is manufactured by fixing and degreasing of the mixture in a die and sintering of the mixture at a temperature of 1,400 DEG C; and the finger ring blank after sintering forming is processed by various techniques such as grinding, CMC wire cutting, electric spark and so on, and the finished product finger ring is finally formed. Therefore, the novel material finger ring has the characteristics of high strength of material matrix, large and stable friction coefficient, high hardness, capability of guaranteeing strong abrasion resistance on the friction surface, long service life, beautiful and elegant appearance and so on.

Description

technical field [0001] The present invention not only relates to a general method for making a ring, but also a ring and a process firstly made of tantalum as a raw material. technical background [0002] Gold, silver, platinum and other softer materials are mostly used as raw materials for traditional ring making, because these metals are highly malleable and very easy to pour, forge or mold. But at the same time, these materials are also susceptible to scuffs, scratches, and other damage, which can greatly reduce their service life and cosmetic value. Once formed, tantalum is a very hard metal. Because of this, it is difficult to shape, requiring special processing procedures and grinding tools to change their configuration and appearance. We found that in the powder metallurgy sintering process, tantalum can be used in the field of jewelry. In addition, this material, if used in ring manufacturing, can also protect the precious metal and gemstone jewelry set in the rin...
