Problems solved by technology
Anodized pores need to grow at a slow rate in a stable, uniform electric field and an appropriate electrolyte, and the honeycomb network structure is a single metal oxide, and there are interfaces between pores, resulting in low strength of the entire material
[0007] Therefore, the above-mentioned methods all have certain limitations, and there is no method that can be applied to a variety of metals, and can uniformly and controllably construct a pure metal porous structure on the surface of the material for the material that has been formed.

Embodiment 1
[0032] like figure 1 As shown, the metal sample to be treated is CuZn30, and it is processed according to the above steps. The liquid medium is stored water, and the metal sample is treated with 1MHz ultrasonic wave in pure water for 60 minutes. The porous structure that appears on the metal surface is as figure 1 shown.
Embodiment 2
[0034] like figure 2 As shown, the surface of the metal sample CuZn30 was treated with 1 MHz ultrasonic waves for 10, 30 and 60 minutes in pure water, and the porous structure appeared on the surface.
[0035] from figure 1 and figure 2 It can be seen that the longer the treatment time, the larger and more pores, and the ultrasonic input power will affect the area of the treated surface and the shape and size of the pores.

The invention discloses a device and a method for assisting manufacturing of a metal porous foil. The device comprises an ultrasonic transducer and a liquid vessel which contains a liquid medium; anda metal sample is fixed in the liquid medium in a suspending manner. A manufacturing method for multiple pores comprises the following steps of 1) device building: a liquid vessel is placed on the upper surface of the ultrasonic transducer, the liquid medium is injected into the liquid vessel, and a constant-temperature water bath device is connected with the liquid vessel through a connecting pipeline; 2) metal sample fixing: a metal sample to be treated is suspended in liquid and is thoroughly immersed into the liquid; and 3) manufacturing of the multiple metal pores. The device provided bythe invention is simple in structure and liable to operate. In the manufacturing method for the multiple metal pores, the micron-sized pores are manufactured on the surface of metal with assistance ofultrasonic waves; and compared with existing manufacturing of the multiple metal pores, the method is simple and convenient as well as is liable to implement and relatively strong in universality.
Description
technical field [0001] The invention belongs to the technical field of metal porous manufacturing, and in particular relates to a technology for manufacturing porous technology by using ultrasonic vibration to catalyze chemical corrosion reaction. Meanwhile, the technology also belongs to the application of local physical damage caused by ultrasonic vibration. Background technique [0002] The manufacturing methods of porous metals can be roughly divided into four types due to the limitation of high hardness and high melting point of metals. The first is a foaming method in which gas is blown into the molten state to create pores and cooled. This method can obtain metal foam with extremely high porosity, but its pore size is large, and it can only be produced in the forming process, and the alloy composition is also limited to alloys in a molten state. [0003] The second is the widely commercialized sintering method: the metal powder is thoroughly mixed with the pore-formi...
