MICROWAVE-ASSISTED PRODUCING CLOSED-CELL ALUMINUM FROTH
Keywords:
aluminum froth, closed-cell, microwave, high-strength, high durabilityAbstract
This work constitutes a contribution of authors to making microwave-assisted closed-cell aluminum froth. The required aluminum powder was obtained as a result of the own method applying by nitrogen jet atomization of the molten metal through rapid microwave heating, the solidified aluminum grains being very fine (under 10 µm). Reducing the aluminum powder granulation influenced the foam denseness decrease in the range of 0.45-0.82 g·cm-3 and the increase of its porousness up to 80.8 %. Depending on the size of the cell structure, the compression strength varied between 3.8-7.3 MPa. The main application areas of these froths are energy and respectively, sound absorption, electromagnetic shielding, and vibration damping.References
