Embodiment Construction

[0033] Below in conjunction with accompanying drawing and example the present invention will be further described:

[0034] Such as figure 1 and figure 2 As shown, the ultrasonic vibration-assisted laser cladding composite processing device of the present invention includes a test block [1], a horn [2], a flange [3], a transducer [4], and a cooling fan [5] , column bracket [6], cable [7] and ultrasonic generator [8]. Grind the surface of the substrate test block [1] to be clad flat, then wipe the surface with acetone to remove oil stains, fix the test block [1] and the horn [2] with bolts, and then use the cable [7] to generate ultrasonic waves Device [8] is connected with transducer [4]. The powder to be clad is preset on the surface of the test block, the laser head is moved to the position to be clad, and the ultrasonic generator and laser are turned on at the same time. Turn off the ultrasonic generator after cladding to achieve the purpose of refining the structure ...

Abstract

The invention relates to supersonic vibration-assisted laser cladding composite processing equipment. Supersonic vibration is synchronously exerted on a matrix sample in a laser cladding process; the crack sensitivity of a laser cladding layer is reduced; and the tissue is refined. The laser cladding composite processing equipment is characterized in that 1 the composite processing equipment comprises a test block (1), an amplitude-change pole (2), a flange (3), a transducer (4), a cooling fan (5), an upright post bracket (6), a cable wire (7) and an ultrasonic generator (8); 2 a base plate is a flat test block; preheating is not required before treatment; and slow cooling is not required after treatment; 3 the variety of cladding powder is not limited; 4 the test block (1) is connected with the amplitude-change pole (2) through bolts; 5 the cooling fan (5) is used for discharging heat generated when the device works; and 6 the ultrasonic generator (8) is connected with the transducer (4) through the cable wire (7); and ultrasonic vibration is transmitted to the test block (1) through the amplitude-change pole (2). The supersonic vibration-assisted laser cladding composite processing equipment is high in processing efficiency, simple to operate, and free of pollution to environment, and a cladding layer which is free of a crack in surface and fine in internal texture is obtained.

Description

technical field [0001] The invention relates to an ultrasonic vibration-assisted laser cladding composite treatment device, which belongs to auxiliary equipment in the material surface treatment process. The device is especially suitable for the field of laser surface processing. Background technique [0002] Laser cladding technology refers to placing the selected coating material on the surface of the coated substrate in different ways of adding materials, melting it and a thin layer of the substrate surface at the same time through the high-energy laser beam, and forming a very low dilution after rapid solidification. , A surface coating that forms a metallurgical combination with the base material, thereby significantly improving the wear resistance, corrosion resistance, heat resistance, oxidation resistance, etc. of the base material surface. As an emerging technology in the field of surface engineering technology, laser cladding has become a relatively active technol...
