Description
Technical field
The invention belongs to field of surface engineering technique, specifically relate to a kind ofly in titanic alloy machining process, to its surface, there is protection against oxidation and the protective coating from peel-ability.
Background technology
Titanium alloy has that density low and high temperature intensity is good, creep resisting ability is strong and fusing point advantages of higher, has become the focus material of aerospace industry and high-tech product at present.But in high-temperature heat treatment process, oxygen generation oxidizing reaction in titanium alloy surface and air, one deck oxide skin and hard and crisp surperficial infiltration layer is formed on its surface, this not only makes the titanium alloy accounting for charging capacity more than 2.2% lose, but also cause very large difficulty can to postorder hot-work, even make whole alloy workpiece scrap.Therefore, in hot procedure, prevent titanium alloy to be oxidized is the effective means improving its quality product and material use efficiency.Coating protection technology is one of minority effective ways addressed this problem, and compared with vacuum protection technology and protection of inert gas hot-working process, it has the advantages such as the hot-work that coated technique is simple, protected effect is remarkable, cost is low, be applicable to large workpiece.
But; the development of China to titanium alloy hot-work supercoat is unsatisfactory; and the existing initial feed for the preparation of titanium alloy inoxidzable coating is all analytical pure or commercially pure metal oxide and nonmetal oxide; and; in order to reach low temperature and softening effect, in coating ingredients, usually add a certain amount of environmentally harmful lead element.
Summary of the invention
The object of the present invention is to provide a kind of titanium alloy high-temperature protective coating utilizing trade waste boron mud and cullet to prepare for raw material.This coating can directly be brushed at titanium alloy workpiece on the surface, and forms high hat resistant cover in hot procedure, reaches the oxidization burning loss reducing titanium alloy, improves the object of volume recovery and titanium alloy surface quality; Coating has in the process of cooling after thermal treatment completes from the ability that titanium alloy surface peels off certainly simultaneously.
Another object of the present invention is the application providing described titanium alloy hot-work antioxidizing paint.

A kind of method preparing coating at titanium alloy surface: adopt suitable brushing method by above-mentioned coating brushing at the titanium alloy workpiece through purification on the surface, titanium alloy sample after coating is put natural air drying 1 ~ 2 hour in atmosphere, then puts into dry 1 ~ 2 hour of the air dry oven of 100 DEG C.
This coating can form continuous print supercoat under high temperature action, effectively reduces the high temperature oxidation scaling loss of titanium alloy in hot procedure, and does not change the original performance of titanium alloy workpiece matrix.
Suitable brushing method, when referring to coating, brush pen will accomplish that single direction is brushed, and does not brush back and forth, ensures that coating does not have bubble, coating evenly.About 150 ~ 300 μm of the thickness of coating, can control coat-thickness by repeatedly brushing.
Purification metallic substrate surface, refers to that the coverture eliminating those self-assembling formations goes out the surface of metal natural colour and surface crystal structure from surface open.Its main contents select appropriate means to remove natural cover exactly, reach and required cleanliness factor.The surface smoothness of this technical requirements metal base is 600
#, and surface is without grease, rusty stain, dirt etc.(such as: adopt sand papering workpiece surface to remove surface covering, and reach respective surfaces smooth finish; Again with alcohol or acetone cleaning workpiece surface and oil contaminant etc.）
The invention has the beneficial effects as follows:
1. environmental protection, with low cost.Titanium alloy hot-work surfacecti proteon coating of the present invention, selected most of raw material is trade waste and raw mineral materials, achieves the recycling of waste, turns waste into wealth, alleviate problem of environmental pollution, reduces the cost of coating simultaneously; In addition, this coating, under the prerequisite not containing harmful Element Lead, can provide good protection against oxidation the temperature range of 500 ~ 900 DEG C for titanium alloy.
2. technique is simple, applied widely.Because this coating is with water base water glass for binding agent, with the powder below 100 orders for being contained in bonding in aggregate or auxiliary packing, brush on pretreated metallic surface, natural air drying as paint, Conventional cryogenic drying forms coating.It does not need expensive equipment, and technique is simple, and to the shape of workpiece and size all without any restrictions; In addition, this technique is nontoxic, pollution-free, can be suitable for most environment.
3. coating protection is effective, is easy to remove.In 500 ~ 900 DEG C of high-temperature heat treatment process; coating of the present invention can form rapidly the supercoat of one deck densification on titanium alloy workpiece surface; effectively prevent the infiltration of extraneous oxidizing gas; for providing good protection against oxidation in titanium alloy hot procedure; and after titanium alloy workpiece heat treatment completes and comes out of the stove
In process of cooling, this coating very easily to be peeled off and without the need to carrying out extra process automatically from titanium alloy surface.
