High-temperature wave-absorbing material containing dendritic nickel ceramic matrix and preparation method of high-temperature wave-absorbing material
The invention discloses a high-temperature wave-absorbing material containing a dendritic nickel ceramic matrix and a preparation method of the high-temperature wave-absorbing material, relates to the field of wave-absorbing stealth materials, and aims to solve the problems that a wave-absorbing agent of an existing wave-absorbing material is easy to oxidize in a high-temperature service environment and the wave-absorbing performance is relatively poor. The high-temperature wave-absorbing material is formed by compounding dendritic nickel and a ceramic matrix. The method comprises the following steps: 1, grinding, polishing and cleaning an electro-deposition cathode material and an anode material; 2, preparing an electro-deposition plating solution; 3, the electro-deposition plating solution is poured into an electro-deposition tank, the annular nickel sheet is placed into the electro-deposition tank, a quartz glass sheet is placed at the bottom of the electro-deposition tank, and an electro-deposition cathode material is located on the upper portion of the center of the glass sheet; switching on a power supply for electro-deposition; 4, cleaning the dendritic nickel; 5, drying the ceramic matrix raw material; 6, adding the dendritic nickel into the ceramic matrix raw material, uniformly mixing, and carrying out compression molding to obtain a ceramic matrix green body containing the dendritic nickel; and 7, sintering and densifying the ceramic-based green body to obtain the dendritic nickel-containing ceramic-based high-temperature wave-absorbing material. The method is used for preparing the wave-absorbing material.
