The method that gold surface different colours.
Background technology
Titanium is a kind of silver grey non-ferrous metal, and quality is slim and graceful, high mechanical strength, because surface easily forms dense oxidation film,
There is excellent antiacid caustic corrosion, both high temperature resistant and low temperature resistant.In industrial heat exchange device, reactor, building materials, electronic component, essence
The aspects such as close instrument, advanced camera, notebook computer are applied widely, have currently become in aerospace industry and have manufactured rocket motor
The housing of machine and the important materials of artificial satellite, spacecraft.
Because titanium quality is softer, rub resistance is poor；Color is single, and aesthetic property is poor.Therefore improve titanium surface color become work as
Front important subject.Introducing nitrogen, oxygen, carbon are greatly improved the intensity of titanium, titanium surface electrochemistry as titanium interstitial impurity
Process, not only improve surface texture performance, also can produce different surface colors.At metallic titanium surface chemical treatment and electrochemistry
Reason, is the important channel improving surface of metal titanium feature and surface of metal titanium color.Borax treatment method, surfaces nitrided method, swash
Light fusing-particle injection method, quench-hardening tini method with plastic film, electroplating surface hardening process are the important sides strengthening titanium case hardness
Method；Air heated oxide method, surface alloying, ion implanting facture, noble coatings method are to prevent important the arranging of titanium corrosion
Apply；Aluminum diffusion coating technology is to prevent titanium high-temperature oxydation and reduce the important measures that titanium inhales hydrogen embrittlement.In the surface treatment of numerous titaniums
In technique, electrochemical anodic oxidation technique course is simple, and the superficial film various aspects of performance of acquisition is excellent.
Wherein the chemical oxidization method of titanium, air heated oxide method, three kinds of titanium method for coloring surface of anodizing compare, sun
No matter most valuable from tinctorial quality, surface texture, process safety, Environmental security pole oxidizing process is.Can by anode oxidation coloration
Reach color spectrum titanium.Promote with Titanium anode oxidation process, titanium surface texture, feature, aesthetic property more and more higher.
In electrochemical anodic oxidation facture, decomposition voltage is the major influence factors in anode oxidation process parameter, with
The color of the change anode oxide film of decomposition voltage is in regular change.Meanwhile, the composition of electrolyte, concentration are all to the complexion changed time
There is different degrees of impact.
As a kind of method of surface modification, anode oxidation process has been started one and has been improved material function and aesthetic property
New way.Oxide-film rich color obtained by anode oxidation coloration, film layer is relatively thin, and stable crystal form possesses good surface
Corrosion resistance, wearability, thermostability.As the technique of titanium coloring, process is simple it is achieved that the combination of base material and film layer,
Achieve the raising of titanium surface-functional.
Therefore, from anode oxidation process, titanium is carried out with coloring research, mainly inquire into anodised technological process, bag
Include surface of metal titanium pretreatment, electrolyte selects, pole plate selects, polar plate area is than determination, electrolyte temperature, decomposition voltage, oxygen
Change time, color and luster determine, film performance is inquired into.Optimization technological process, determines optimum process scheme.
Content of the invention
Invention broadly provides a kind of method for anodizing and coloring surface of Titanium, the Ti content of wherein Titanium is big
In equal to 99.99%.The method is with low cost, simple to operate, easy to control, coloring stabilized, is a set of perfect metal Ni-Ti anode
Heat-tinting new technology.This technique, on the basis of determining coloring liquid, only passes through constant coloration voltage, control coloration time can
To obtain desired titanium surface color and polish in specific range of temperatures, and surface color and polish is stable, good quality.Coloring with the present invention
Technique can obtain the high-quality metal titanium products of the solid colour meeting performance requirement.
In order to achieve the above object, technical solution of the present invention comprises the following steps:
Anodizing solution of the present invention is with water as solvent, and every liter of solution includes:

Present invention titanium to be colored need to be washed pickling pure water through pure water soda and be washed, then carries out at anodic oxidation
Reason.
The cathode plate of electrolyzer of the present invention is high-density graphite, and anode is pretreated titanium to be colored, negative electrode pole
Plate suqare and positive plate appearance profile frontal projected area ratio 5 1～1 1, polar plate spacing 1～60mm.Pole plate space set, the
One piece of pole plate and the last block pole plate are minus plate, with pole plate between voltage improve, polar plate spacing accordingly increases.
Anodic oxidation voltage 1～36v of the present invention, oxidization time time 30s-1200s.
The titanium metal work-pieces of the different surface treatment such as anodizing solution pigmentable polishing of the present invention, turning, sandblasting, and can protect
Hold titanium surface initial condition and can guarantee that color even is consistent.
Electrolytic oxidation gained oxide-film of the present invention is combined stable, lovely luster with matrix, has good decorative appearance effect
Really, higher case hardness, good corrosion resistance, in atmosphere temperature reach less than 200 DEG C no color and luster and structural mutations.
Under setting electrolytic oxidation voltage, oxidization time, oxidizing temperature fluctuation affect very weak the present invention on color consistency.
The excellent results of the present invention are:
Part surface treatment to be colored is simple, and autoxidation film layer is gone in decontamination of deoiling it is ensured that former Workpiece structure pattern is constant.
Heavy metal element, no poisonous and harmful element environmental pollution is not contained in electrolyte.Work circumstances safe is preferable.
