The invention relates to a high-performance tungsten / steel composite material based on high-temperature application and a preparation method thereof and belongs to the technical field of preparation of composite materials. By adoption of the high-performance tungsten / steel composite material, the problems of large residual joint stress, low strength, poor heat resistance and high connection temperature in an existing tungsten / steel connector are solved. The high-performance tungsten / steel composite material is prepared from a tungsten-based layer, a titanium layer, a niobium layer, a nickle layer and a steel-based layer which are arranged in sequence and prepared by adopting a welding method. The high-performance tungsten / steel composite material is obtained by superposing the tungsten-based layer, the titanium layer, the niobium layer, the nickle layer and the steel-based layer in sequence according to the superposition mode of the tungsten-based layer, the titanium layer, the niobium layer, the nickle layer and the steel-based layer and carrying out vacuum diffusion bonding. The high-performance tungsten / steel composite material has the advantages that the room-temperature tensile strength is larger than or equal to 352MPa, and the tensile strength at the temperature of 650DEG C is larger than or equal to 338MPa; the structure design is reasonable, the process is simple, the large-scale application is convenient, and simultaneously, the high-performance tungsten / steel composite material can be widely applied in diffusion bonding of refractory metal and other dissimilar metal materials.

The invention discloses a thermoplastic elastic self-sealing film and a preparation method thereof. The film is mainly prepared from the following components in part by weight: 100 parts of matrix resin, 100 to 140 parts of wax, 10 to 100 parts of thickening agent and 1 to 30 parts of filler. The preparation method comprises the following steps of: fusing and mixing the components except the matrix resin in a ratio; adding the matrix resin, and performing fusing and mixing; and delivering the obtained melt to a hot melt T-shaped crack die head for coating, rolling and forming the film. The thermoplastic elastic self-sealing film has the advantages of no stickiness on the original surface of the film, easy packaging and transporting, no stickiness to hands, and ideal permeability and resilience; and the preparation process is simple and easy to operate.

The invention discloses a self-balancing pressure-resistant casing device, and belongs to the technical field of a bathyscaphe pressure-resistant structure. The self-balancing pressure-resistant casing device is formed by sequentially sleeving and installing a ball-shaped inner casing, a ball-shaped middle casing and a ball-shaped outer casing around the ball center from inside to outside, wherein the ball-shaped inner casing and the ball-shaped middle casing are connected through a pair of symmetrical and coaxial connecting shaft assemblies; the ball-shaped middle casing and the ball-shaped outer casing are connected through a pair of symmetrical and coaxial connecting shaft assemblies; the axial lines of the two pairs of connecting shaft assemblies are mutually vertical, so that the ball-shaped inner casing and the ball-shaped middle casing can mutually rotate, and the ball-shaped middle casing and the ball-shaped outer casing can mutually rotate; each of the two pairs of connecting shafts is provided with a spring damper; the axial impact between the adjacent casings is resisted. The self-balancing pressure-resistant casing device has the advantages that a control system is simplified; the work reliability and the operation stability of a bathyscaphe are improved; the noise is a cabin is reduced; the work environment comfort of aquanauts is improved; the work safety of the bathyscaphe is improved; the material selective range is expanded; the thickness of the casings is reduced; the processing difficulty of the casings is reduced.
