Description
Technical field
The invention belongs to material surface modifying technology field, particularly to a kind of Large Titanium and titanium alloy product weld seam anode
The cathode assembly of oxidation.
Background technology
Titanium is one of more rich element of reserves in the earth's crust, and its abundance in the earth's crust is about 0.64%, in structural metal
In be only second to aluminum, magnesium and ferrum and occupy the 4th.Titanium or titanium alloy is due to having low-density, highly corrosion resistant, high intensity are become reconciled
The advantages of plasticity, it is widely used in the industrial departments such as oil, chemical industry, shipbuilding.But because Large Titanium and titanium alloy product size are big,
The reason such as complex-shaped, preparation during it is often necessary to soldering is carried out to titanium or titanium alloy component, and weld seam and
Heat affected area fe content is higher, in use, is affected by factors such as environment, these regions are more tight as anodic attack
Weight, have impact on the service life of titanium article.
Anodizing, is that a kind of generation using electrochemical reaction aoxidizes film method.Its principle is logical between two electrodes
After electricity, metal is spread in the presence of electric field with oxonium ion, finally forms oxide-film on anode metal surface.With respect to titanium
And titanium alloy others surface treatment means, anodizing has a process is simple, low cost, the oxide-film wearability being formed,
Corrosion resistance preferably, be industrial be easily achieved, frequently with method.
Content of the invention
It is directed to titanium or titanium alloy large product weld metal zone perishable, realize anodized difficulty and oxygen in weld metal zone
Change film layer problem of non-uniform, the invention provides a kind of anodised cathode assembly of titanium or titanium alloy large product, it is permissible
There is provided continuous, stable electrolyte for anodic oxygen chemical process.
Using technical scheme it is:
A kind of anodised cathode assembly of titanium or titanium alloy weld seam, including feed pipe, negative electrode pen, negative electrode, negative electrode
Jacket.Negative electrode pen and negative electrode are made using graphite material.Negative electrode pen is column type, and there is hole inside, and one end is provided with female thread and confession
Liquid pipe is threaded, and the other end is provided with external screw thread and is threadeded with negative electrode.Negative electrode can add according to oxidized anode plants profile
Work become respective shapes as shown in Figure 1, Figure 2, Fig. 3, to ensure that negative electrode and positive contact face fit as far as possible.Cathode internal is provided with confession fluid apertures,
Confession fluid apertures are connected with feed pipe by negative electrode endoporus, average branch some apertures on negative electrode binding face, aperture with interior
Portion's confession fluid apertures connection, to ensure the uniform and stable branch of electrolyte on binding face in oxidizing process.
There is negative electrode jacket outside negative electrode.Jacket is made using the high hot pressing sponge of good water absorption, wearability, in oxidizing process,
Electrolyte passes through feed pipe and confession fluid apertures, makes negative electrode jacket be saturated with electrolyte, anode and negative electrode relative motion carry out anodic oxidation,
By adjusting the electrolyte ensureing to consume in anode oxidation process for flow quantity.
In oxidizing process, electrolyte is connected with confession fluid apertures by feed pipe, makes negative electrode jacket be saturated with electrolyte, anode and the moon
Pole relative motion carries out anodic oxidation, by adjusting the electrolyte ensureing to consume in oxidizing process for flow quantity.
The invention has the beneficial effects as follows: it is provided with the negative electrode of confession fluid apertures due to employing inside, can be made by flow-control
Negative electrode jacket is in electrolyte all the time and is saturated with state, thus ensureing the stability of various process parameters in anode oxidation process,
And then obtain the oxidation film layer of uniformity.
