Description
Technical field
The invention belongs to titanium alloy material processing technology field, be specifically related to the surface process side of a kind of titanium alloy thin material
Method.
Background technology
Titanium alloy is as light metal alloy, high owing to having specific strength, and corrosion-resistant, nonmagnetic, solderability
Deng excellent properties, it not that aerospace field is used widely in industries such as Aero-Space, chemical industry, naval vessels.
It is known that titanium is a kind of high activity metal element, easily form oxide with the oxygen in air.Due to titanium alloy
Part has the advantages that surface activity is strong, and titanium alloy material heat treatment rear surface more than 500 DEG C produces one layer of 0.0025mm extremely
0.004mm heavy scale.The oxide-film of titanium alloy surface not single structure.At oxide-film and titanium interface with TiO2、
Ti2O3It is main with TiO, the most also can there is the alloy solid solution oxidized compounds such as Ti-Al, Ti-Mo, Ti-V, Ti-Fe, Ti-Zr,
Just because of this multiple structure, the cleaning of oxidizing skin is removed and is brought many difficulties.
Titanium is irreversible with the reciprocal action of oxygen, and oxide skin is firmly combined with matrix, is difficult to remove.Piece surface
Part quality and existence in service life are had a strong impact on by oxide skin, it is necessary to after removal, part can meet use demand.At present,
Scale removal mainly has a two ways: chemical method (alkali, pickling) and Mechanical Method (sandblasting or polishing).Alkali, acid wash are on rule
The method soaking scale removal in fixed acid, alkaline concentration and the time, but there is oxide skin and remove the most thorough in the method
And " suction hydrogen " phenomenon, it is difficult to ensure that the surface quality of product, and environmental pollution is serious.Oxide skin remains, and has a strong impact on titanium and closes
Metal parts surface quality and being normally delivered for use.By mechanical grinding, matrix easily occurs cut, easily hurts by sandblasting way
Matrix surface, can produce cementation zone simultaneously, thus reduce the performance such as the mechanics of materials, corrosion, and both approaches compares expense
Time, laborious.
Titanium alloy product reaches certain performance indications and could use after typically needing heat treatment, therefore heat treatment step must not
Can lack, for the problem of the oxide skin difficulty removal that titanium alloy component in heat treatment process produces, researchers the most once taked various
Measure, carries out application of vacuum as controlled the atmosphere in heating furnace, but effect is unsatisfactory, and vacuum heat cost is high, and
Rate of cooling is uncontrollable, is therefore badly in need of a kind of new processing technique, meets part heat treatment surface requirements.
Summary of the invention
The technical problem to be solved is for above-mentioned the deficiencies in the prior art, it is provided that a kind of titanium alloy thin material
Surface treatment method.The method efficiently, environmental protection, low cost, it is possible to be prevented effectively from titanium alloy thin material surface shape when heat treatment
Become deep oxidation skin and the difficult problem removed, while reducing metal consumption, it is possible to preferably ensure the surface quality of product
And method is simple, cost is relatively low.
For solving above-mentioned technical problem, the technical solution used in the present invention is: the surface process side of a kind of titanium alloy thin material
Method, it is characterised in that the method comprises the following steps:
Step one, by glass dust, binding agent and water mix homogeneously, obtain mixed liquor；Described glass dust, binding agent and water
Addition is: every 1kg glass dust adds 1L～2L binding agent, adds 4L～6L water；
Step 2, titanium alloy thin material is placed in electric furnace preheating, then mixed liquor even application described in step one is existed
Titanium alloy thin material surface after preheating, carries out heat treatment to the titanium alloy thin material being coated with mixed liquor afterwards；Described titanium alloy is thin
Material is titanium-alloy thin-plate or thin-wall workpiece, the thickness of slab of described titanium-alloy thin-plate and the wall thickness of thin-wall workpiece no more than
10mm；
Titanium alloy thin material after heat treatment in step 2 is processed by shot blasting by step 3, employing nylon abrasive band, obtains table
Titanium alloy thin material after the process of face.
The surface treatment method of above-mentioned a kind of titanium alloy thin material, it is characterised in that binding agent described in step one is ZS-
1071 type inorganic high-temperature resistant binding agents.
The surface treatment method of above-mentioned a kind of titanium alloy thin material, it is characterised in that titanium alloy thin material described in step 2
For beta titanium alloy thin material.
The surface treatment method of above-mentioned a kind of titanium alloy thin material, it is characterised in that the temperature of preheating described in step 2
Being 100 DEG C～200 DEG C, the time of described preheating is 20min～30min.
The surface treatment method of above-mentioned a kind of titanium alloy thin material, it is characterised in that heat treatment described in step 2 is solid
Molten aging strengthening model.
The present invention compared with prior art has the advantage that
1, the principle of the present invention is: titanium alloy thin part is heated commonly to 700 DEG C of left sides when solid-solution and aging heat treatment
The right side, in glass dust, the inorganic silicon of content can form one layer of fine and close inorganic silicate ceramic-like film layer, by titanium alloy component surface
Carry out isolation with air to play a protective role, thus be effectively prevented oxygen atom and penetrate into formation oxide skin in the middle of titanium material.Owing to not having
Have and form the oxygen diffusion layer that hardness is higher, use plastic nylon abrasive band to be processed by shot blasting thin-wall workpiece to remove easily
It is coated in the glass dust mixed liquor of piece surface, reaches the effect of any surface finish.
2, processing titanium alloy thin material according to surface treatment method of the present invention, after heat treatment, piece surface will not be formed
Deep oxidation skin, is not required to carry out time-consuming, the laborious subsequent treatment such as alkali, pickling or mechanical treatment, do not exist environmental pollution and
While extremely low metal loss, it is possible to preferably ensureing surface quality and the dimensional accuracy of product, and method is simple, cost is relatively
Low.
3, the present invention efficiently, environmental protection, low cost, it is possible to be prevented effectively from titanium alloy thin material surface when heat treatment and form the degree of depth
Oxide skin and the difficult problem removed, while reducing metal consumption, it is possible to preferably ensure surface quality and the method for product
Simply, cost is relatively low.
