Embodiment 1

[0027] The preparation method of titanium alloy base diatomite barium iron oxide composite material of the present invention, it comprises the following steps:

[0028] a. Preparation of diatomaceous earth iron oxide barium complex:

[0029] 1. Dissolve ferric chloride, barium nitrate and citric acid in a weight ratio of 1:5:5 and add a small amount of water to form a mixed solution of the three, then put them into diatomite, stir in a water bath at 80°C for 10-20min, silicon The size of the diatomaceous earth is 0.5mm, and the weight ratio of the three mixed solutions to the diatomite is 5:1. After the stirring is completed, place the stirred material in an oven at 120°C for 30 minutes and cool it naturally, and then put it in a 550-590 In an oven at ℃, keep warm for 30 minutes and then cool naturally to obtain diatomite barium iron oxide compound;

[0030] 2. Then put ferric chloride and ammonium ferrous sulfate into a hydrothermal container with Teflon lining, add water to...

Embodiment 2

[0035] a. Preparation of diatomaceous earth iron oxide barium complex:

[0036] First add ferric chloride, barium nitrate and citric acid in a weight ratio of 1:10:20 and add a small amount of water to form a solution, and the weight ratio of the solution to diatomite is 10:1 to obtain diatomite iron oxide barium complex. Diatomaceous earth has a size of 0.5-1 mm.

[0037] Then ferric chloride, ferrous ammonium sulfate and diatomaceous earth iron oxide barium compound obtained above are formulated in a weight ratio of 1:1:2.

Abstract

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.
