Problems solved by technology

[0004] Apply the traditional surface treatment technology that has been successfully applied in the iron and steel field to the surface of titanium materials, specifically: surface heat treatment, surfacing, multi-layer composite, coating, hot-dip coating, conversion coating, coloring, vapor deposition, thermal Spraying, electroless plating, hot-plating, etc. These methods are mainly to improve the functionality of the titanium surface, and some can achieve some decorative effects, but this special crystal pattern cannot be obtained
[0005] Combining the characteristics of titanium materials, develop new surface treatment technologies, specifically: liquid phase plasma surface treatment (including micro-arc oxidation, cathode carbonitriding) and glow plasma surface metallurgy technology. Improved functionality and complicated operation
[0006] Titanium products with a certain texture are processed by mechanical treatment methods such as polishing, sandblasting, and wire drawing, but this kind of decorative effect is relatively common and single, and does not reflect the originality

Embodiment 1

[0035] A method for processing crystal patterns of titanium products, specifically comprising the following three steps:

[0036] The first step: heat treatment of titanium products under vacuum conditions, including the following steps:

[0037] Step 1.1, vacuum treatment, specifically: in vacuum (vacuum degree is 6 * 10 -2 Pa) conditions, the titanium product is raised from room temperature to 1050°C for 2 hours, and then kept for 2 hours;

[0038] Step 1.2, cooling treatment, specifically: filling with argon (the pressure when backfilling with argon during cooling is set to 2.3 bar), and cooling the titanium product to 60° C. in 3 hours to obtain a heat-treated titanium product.

[0039] Step 2: Grinding the titanium products after heat treatment, specifically: use the abrasive tools of 400#, 800# and 1200# to carry out rough grinding, medium grinding and fine grinding on the titanium products in turn, and polish to bright (rough degree Ra<0.1μm).

[0040] The third step...

Embodiment 2-3

[0043] The difference between embodiment 2-3 and embodiment 1 lies in table 1.

[0044] The effect diagrams of the titanium products with patterns obtained in Examples 2-3 are shown in detail respectively image 3 with Figure 4 .

[0045] Table 1 embodiment 1-3 and the process parameter comparison table of comparative example 1-2

[0046]

[0047] Combining Table 1 and Figure 1-Figure 6 It can be seen that:

[0048] The combination of Embodiment 1, Embodiment 2 and Embodiment 3: the heat treatment temperature is 1000°C-1200°C, which can make the surface of titanium products obtain abnormally coarse grains (up to 1-5mm), and then grind and pickle Process, the grain boundary is corroded, so that the grain boundary between the grains is clear, and the effect is visible to the naked eye. The crystal flower effect with metallic luster can be seen with the naked eye, and the product yield is high. Different heat treatment temperatures result in different coarse grain sizes...

Abstract

The invention provides a processing method for crystal patterns of a titanium product. The processing method comprises the following steps that firstly, the titanium product is heat-treated under the vacuum condition; secondly, the heat-treated titanium product is polished; and thirdly, the polished titanium product is acid-pickled, and thus the titanium product with the crystal patterns is obtained. The processing method has the following effects that (1), the method comprises the three steps of heat treatment, polishing and acid pickling, the technical steps are simple, and industrial production is facilitated; (2) abnormally-thick titanium crystal grains (the size of each crystal grain can reach 1-5 mm) are obtained through heat treatment firstly, then the crystal boundaries are corroded through the polishing and acid pickling technique, so that the grain boundaries among the crystal grains are clear and visible to naked eyes, the naked eyes can see the crystal patterns with metal luster through observation, and the product yield rate is high; and (3) technical parameters in the processing process are convenient to control, reagents are easy to obtain, and the processing cost is low.

Description

technical field [0001] The invention relates to the technical field of surface treatment of titanium products, in particular to a method for processing crystal patterns of titanium products. Background technique [0002] With the continuous expansion of the application field of titanium materials, in order to solve the problems generated during the use of titanium materials, and at the same time in order to meet consumers' needs for the surface craftsmanship of titanium products, domestic and foreign scholars have carried out a lot of research on the surface treatment technology of titanium materials. Research. [0003] In the prior art, the surface treatment of titanium or titanium products mainly includes the following three aspects: [0004] Apply the traditional surface treatment technology that has been successfully applied in the iron and steel field to the surface of titanium materials, specifically: surface heat treatment, surfacing, multi-layer composite, coating, ...
