Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1
As shown in fig. 1 to 3, the method for preparing a precise and efficient color titanium alloy by using laser processing comprises the following steps:
the parameters of the cross-scan are shown in Table 1, and the parameters of the single scan are shown in Table 2.
TABLE 1 parameters of Cross-Scan
TABLE 2 parameters of a single scan
And 4, carrying out laser coloring, then carrying out ultrasonic cleaning on the titanium alloy by using 95% absolute ethyl alcohol again, and airing after the cleaning is finished.
When a complex color image on the surface of the titanium alloy is drawn, compared with the single-color coloring process, the method has the main differences that: the image to be processed is partitioned according to colors, areas with the same color number are respectively extracted and stored into a BMP format, then a plurality of BMP pictures are imported into ezCAD software for processing, and different pictures are sequentially processed by using parameter settings of corresponding colors.
In fig. 1, a is a color object image, and b is a complex image processing image;
in fig. 2, under an optical microscope, only small patches of blue, yellow, magenta and black were observed, which are different from the macroscopically observed colors. The reason is that the resolution of the human eye is 100 μm, and the size of the laser-induced color patch is smaller, which cannot be distinguished by the human eye. And minute color lumps are generated by the uneven oxidation of titanium. The macroscopically appearing color is influenced by the distribution of the oxides on the surface of the material and the resolution of the tiny color patches by human eyes; the corresponding relationship between the microstructure and the macroscopic coloration result in the figure is as follows: 1. yellow 2, orange 3, pink 4, light blue 5, purple 6, brown 7, dark blue 8, green 9, black.
Fig. 3 shows that the number, depth and presence of light trapping holes of the microstructure can be considered to influence the color depth of the surface of the material. It was also found that an increase in the scan pitch increased the brightness of the surface color of TC4, and that the color saturation was highest when the scan pitch was close to the spot diameter (30 μm). The corresponding relationship between the microstructure and the macroscopic coloration result in the figure is as follows: (a) yellow (b) pink, (c-d) orange, (e) violet, (f) light blue, (g) dark blue, (h) green, and (i) black.
Example 2
As shown in fig. 1 and 4, a: the processing area is directly divided by using a circle in the ezCAD, and the transverse/cross filling post-processing is carried out according to the processing parameters of the corresponding color.
b: the image to be processed is divided into regions according to colors, the regions with the same color number are respectively extracted and stored into a BMP format, then a plurality of BMP pictures are sequentially guided into ezCAD software for image scanning processing, and different pictures are sequentially processed by using parameter settings of corresponding colors. Taking b as an example, the processed image used in b is shown in fig. 4, and when processing is performed, a large area of ground color of the image is processed first, and the portion of the image with the emphasized outline is processed optimally, in consideration of the overlapping problem caused by the size of the laser spot.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
