| titleOfInvention | Al (aluminum)2O3Al/Mg layered density gradient material and preparation method and application thereof |
| abstract | The invention particularly relates to ultrathin Al 2 O 3 a/Al/Mg layered density gradient material, a preparation method and application thereof. The Al is 2 O 3 the/Al/Mg density gradient material comprises Al 2 O 3 A layer, an Al layer or an aluminum alloy layer, a Mg layer or a Mg alloy layer; the Al is 2 O 3 The layer is prepared in situ on the surface of aluminum or aluminum alloy by adopting micro-arc oxidation, and the Al 2 O 3 The thickness of the layer is 20-100 microns; the Al is 2 O 3 The thickness ratio of the layer to the Al layer or the aluminum alloy layer is 1-5: 10-25; and the interface bonding strength between the Al layer or the aluminum alloy layer and the Mg layer or the Mg alloy layer is more than or equal to 25 MPa. The preparation method comprises the following steps: by designing electrolyte and based on micro-arc oxidation technology, Al with a thicker compact layer can be obtained in a short time 2 O 3 a/Al/Mg layered density gradient material. The Al2O3/Al/Mg density gradient material designed and prepared by the invention has high surface hardness, and can realize high-efficiency absorption and dissipation of kinetic energy of fragments. It is particularly suitable for the aerospace field. |
