Background technology
Porous metal material with foamy structure is because its special structure formation, not only have weldability, can conduct electricity, general metal properties such as extending, and more demonstrate self characteristic at aspects such as energy-absorbing damping, high damping, noise elimination noise reduction, heat insulation heat exchange, electromagnetic shielding, air-and water-permeables, be widely used in fields such as industry, health care, building trade, environmental protection cause and high and new technology.State according to metal in the preparation process divides, and the preparation method of porous foam metal mainly contains liquid phase method, solid phase method and metal deposition.The foaming of the liquid metal method such as method that can reduce foaming by direct gas-blowing foaming method, metal hydride realizes; The foaming of solid metal can be passed through methods such as powder metallurgic method, powder foam method, metal hollow ball method and metal-powder fiber sintering method and realize; Metal deposition is to adopt the method for chemistry or physics to realize.But all there are some problems in these methods:
1, metal hydride reduces foaming method because the metal hydride decomposition course is restive, and there is the cost problem of higher in the bubble of its formation equally with direct air blast foaming; Because the existence of H forms hydrogen embrittlement easily, worsen the mechanical property of metal again, only be suitable for the foaming of Al, Mg metal, then inapplicable to Ti metal and alloy thereof.
2, the foaming of Al metal can only use direct inflation foaming to prepare foamed metal, but in preparation process, because gathering, the merging of bubble, the pore size in the Al foamed metal is restive, pore size is not of uniform size, thereby the performance of material is produced adverse influence.
Summary of the invention
Be to solve the problems referred to above that prior art exists, the objective of the invention is to propose a kind of preparation technology simple, with low cost, go for that multiple metal foaming and pore size can control prepare the Apparatus for () and method therefor of porous foam metal with the metal melt inflation process.
To achieve these goals, technical scheme of the present invention is as follows: a kind of equipment for preparing porous foam metal with the metal melt inflation process, comprise the metal melt groove, foaming chamber, fluid bore, divider wall, snifting valve, the metallic crystal device, described metal melt groove separates with foaming chamber by the divider wall of band fluid bore, snifting valve is arranged at described foaming chamber top, the side links to each other with the metallic crystal device, the middle part of described metallic crystal device is equipped with the high frequency ultrasound vibrator, described high frequency ultrasound vibrator be used to regulate its vibrational frequency, the high frequency ultrasound power supply of amplitude and watt level connects.
Metallic crystal device of the present invention adopts bolt to be connected with the high frequency ultrasound vibrator.
The experiment power of high frequency ultrasound vibrator of the present invention is 400～500W, and vibrational frequency is 21.8kHz, and amplitude is 1.4～2.0 * 10
-5M, magnetzation current is 6～10A during experiment, screen current is 1～2A.
A kind ofly prepare the method for porous foam metal, may further comprise the steps with the metal melt inflation process:
A, with the METAL HEATING PROCESS in the metal melt groove to about 200-300 more than the fusing point ℃, form metal melt;
B, metal melt is charged into air by tracheae;
