| description | The invention discloses a metal-ceramic gradient composite armor and a manufacturing method thereof, and belongs to the technical field of armors. The composite armor is formed by metal cast ceramic balls which are densely arranged from a bullet receiving surface to a bullet back surface in a volume gradient reduction mode; the diameter difference of adjacent two rows of the ceramic balls is 1 mm,and the thicknesses of the ceramic balls account for 2/3 of the total thickness of the composite armor. The manufacturing method for the armor comprises a ceramic surface pretreatment stage, a ceramic surface silver-plating stage, a metal suction casting preparation stage, a gradient casting manufacturing stage, and a cooling and de-moulding stage. The structure of the laminated composite armor is optimized, so that acoustic resistance mismatch and stress focus among interface layers of the laminated composite armor can be alleviated, firm peripheral restraining of the ceramic balls can be realized, potsherds are pre |
