Abstract
The utility model discloses a titanium alloy member with a cavitation erosion resistant surface, which comprises a substrate and a surface texture layer, and the surface texture layer is provided with a texture structure processed by laser. The texture structure is a mesh or linear or spotted texture. The processing method of the titanium alloy ember comprises the following steps of: pretreating the substrate of the titanium alloy member; and carrying out texture structure processing on the surface of the titanium alloy member with a laser processor to prepare the titanium alloy surface texture layer with intervals of 5 mu m and 100 mu m. In the utility model, after the titanium alloy surface is processed into meshes, linear and spotted texture structures with different intervals, the cavitation erosion resistance of the titanium alloy is obviously improved. Because the laser beam used by the utility model has favorable coherency and directivity, the utility model can ensure that a processed workpiece has no deformation in shape and the problems of loose workpiece structure, weakened binding force and the like cannot be caused.
Description
Technical field
The utility model design relates to a kind of Surface-micromachining process of metallic substance, and particularly a kind of surface has the titanium alloy spare of anti-cavitation property.
Background technology
Titanium alloy is mainly used in fields such as Aeronautics and Astronautics, the energy, Naval Architecture and Ocean Engineering and medical science, and cavitation impingement often takes place in above-mentioned application, therefore is necessary to improve the anti-cavitation corrosion performance of titanium alloy.Surface treatment can effectively improve the anti-cavitation corrosion performance of titanium alloy, but traditional surface modification treatment such as carburizing, boronising and nitriding etc. exist shortcomings such as long processing period and workpiece be yielding; The coating of hot-spraying techniques preparation exist weave construction loose and with the more weak deficiency that waits of the bonding force of matrix.
Summary of the invention
Be to solve the problems referred to above that prior art exists, the purpose of this utility model be a kind of process-cycle of design short, workpiece is indeformable and surperficial titanium alloy spare with higher anti-cavitation property.
To achieve these goals, the technical solution of the utility model is as follows: the titanium alloy spare that a kind of surface has anti-cavitation property comprises matrix and superficial makings layer, and described superficial makings layer has the texture structure with laser processing.
Texture structure described in the utility model is grid or straight line or point-like texture.
Compared with prior art, the utlity model has following beneficial effect:
1, because the utility model becomes grid, straight line and the point-like texture structure of different spacing at titanium alloy surface with laser processing after, the anti-cavitation corrosion wearing character of titanium alloy significantly improves.Particularly for the titanium alloy spare sample of grid texture, produce J93025 type ultrasonic wave cavitation corrosion experimental machine with the Wuxi and carry out cavitation test, experiment power is 200W, vibrational frequency is 21.8kHz, and amplitude is 1.4 * 10-5m, and magnetzation current is 6A during experiment, screen current is 1A, test medium is a distilled water, and uncovered cylindrical container, environment are a standard atmospheric pressure.Carry out the cavitation corrosion experiment after one hour, the cavitation corrosion area is less than 1/10th of polishing titanium alloy spare sample cavitation corrosion area.
2, because the employed laser beam of the utility model has good coherency and directivity, so be widely used in surface modification treatment to various metallic substance.The advantage of laser treatment is that workpiece distortion is less, and matrix is low to the extent of dilution of cladding layer, can more accurately control the width and the degree of depth of processing layer, can selectively handle the particular surface of workpiece, therefore, can guarantee the workpiece shape invariance.
3, because laser processing of the present utility model has the process-cycle weak point, the workpiece shape invariance, and because laser processing is the processing work top layer, and the workpiece interior tissue is not had big influence, so do not cause problems such as the workpiece weave construction is loose, bonding force weakens.
