Abstract: The present disclosure discloses a modular large spherical tank internal detection device with a self-locking function, and belongs to the technical field of safety detection of large spherical tanks. The detection device includes a transmission group and a detection group. A movable pin is matched with the rotation of a second motor in an unconnected state, so that inner central shafts rotate to realize up-down movement of a detecting instrument in a vertical plane. The movable pin is matched with the rotation of a first motor in a connected state, so that the whole detection device rotates round a central axis of a large spherical tank to realize horizontal circumferential movement of the detecting instrument. All detection of a spherical surface inside the large spherical tank can be completed by combining two types of movement of the detecting instrument.

Abstract: The present disclosure relates to the technical field of composite coating preparation, in particular to a method for plasma-assisted and multi-step continuous preparation of a diffusion layer/amorphous carbon film composite coating and use thereof. In the present disclosure, a high-temperature plasma carburizing/nitriding technology and a low-temperature plasma carbon coating technology are combined by a plasma activation technology with argon ion under gradient cooling, and the surface of a material is activated by multiple bombardment on the surface of the material with high-energy argon ions. In this way, a cluster-like porous and loose structure on a surface of the diffusion layer is removed. In summary, the multi-step continuous preparation of the diffusion layer/amorphous carbon film composite coating is formed based on an integrated technology of the high-temperature plasma diffusion with nitrogen/carbon ion and plasma activation with argon ion under gradient cooling and plasma coating with low-temperature carbon ion.

Abstract: The metal ceramic powder with a particle size of 15-45 µm and suitable for thermal spraying is prepared through a combination of mechanical ball milling, spray granulation, and vacuum sintering. The metal ceramic powder is sprayed on a surface of a steel substrate adopting the high velocity oxygen fuel (HVOF) technology with oxygen-propane as fuel and taking oxygen as a combustion improver, propane as fuel, nitrogen as powder feeding carrier gas, and air as a cooling medium to prepare and form the NiCrBSi—ZrB2 composite coating. The present disclosure solves the problem that ZrB2 ceramic is difficult to compact during sintering and improves powder bonding strength and fluidity. The preparation method is simple, has advantages of high coating deposition efficiency and convenient equipment operation, and is cost-effective. The preparation method can improve thermal corrosion resistance and high-temperature wear resistance of a surface of boiler, and prolonging lifetime of the boiler.
