摘要（英）：

The invention provides a titanium alloy, diatomite and barium ferric oxide composite material and a preparation method thereof. The composite material has high absorbing property and excellent damping property. The preparation method is simple in process, low in production cost and suitable for industrialized production. The composite material takes the titanium alloy as the matrix and diatomite and barium ferric oxide compounds are distributed on the matrix. The diatomite and barium ferric oxide compounds account for 45-55% of the composite material by volume. The particle size of the diatomite and barium ferric oxide compounds is 0.5-1mm. The titanium alloy matrix comprises the following chemical components in percentage by weight: 3-8% of Al, 0.001-0.005% of Ta, 0.5-1% of Si and the balance Ti. The diatomite and barium ferric oxide compounds are formed in such a manner that barium ferric oxide penetrates into the pores of the diatomite and a layer of film is formed on the wall surfaces of the pores.
