The invention relates to a doctor blade holder (1) which is configured as a profile strip having a groove (3) extending in the axial direction and receiving the rotatable doctor bar (2). Said doctor bar is forced against a rotating surface and meters and / or levels out a liquid to pasty medium applied to the rotating surface. When the medium is directly applied, the rotating surface is a face of a paper, carton or other fibrous web, and when the medium is applied indirectly, the rotating surface is the surface of a transfer element which transfers the medium onto the fibrous web. According to the invention, the doctor blade holder, in some sections, is configured in the axial direction by at least one insert element (4) which is more resistant to wear and / or heat than the remaining material.

The invention relates to a super-compliant nickel-titanium alloy intracranial vascular stent with a micro-nano structure, which can be used to assist coil embolization in the treatment of intracranial aneurysms, and belongs to the field of medical devices. The main body of the intracranial vascular stent is composed of an open-loop structure and a closed-loop structure. The open-loop structure is formed by connecting the first V-shaped unit arranged in the circumferential direction with the second V-shaped unit arranged in the circumferential direction through connecting rods. The closed-loop structure consists of The second V-shaped units arranged in the circumferential direction are connected by connecting rods, and the ratio of the open-loop free ends of the second V-shaped units to the open-loop free ends of the first V-shaped units is 1:2; the open-loop structure enhances the flexibility of the bracket And adherent, closed-loop construction provides supportive performance. The intracranial vascular stent of the present invention has super-flexible performance, and can be used for assisting coil embolization in the treatment of aneurysms in complex intracranial vessels (such as large-curvature vessels and variable-diameter vessels), achieving good wall-attachment effects.

The invention relates to a novel thermal barrier coating preparation process, which comprises the following steps: forming a metal bonded underlayer on the surface of a substrate; forming an in-situ thermally grown oxide layer (TGO); and forming a ceramic heat-insulating surface layer. The TGO layer is pre-grown before the substrate is put into service. The composition of the TGO layer includes alpha-alumina. In the present invention, a layer of dense and continuous TGO layer mainly composed of α-alumina is preset through large-particle dry ice jet purification and roughening treatment and pre-vacuum argon oxidation treatment. The oxide film will have good resistance to high temperature oxidation, prevent rapid oxidation, reduce the growth rate of TGO layer thickness, and achieve the purpose of reducing the occurrence probability of thermal barrier coating peeling.

The invention relates to high-conductivity polymer-carbon-based composite aerogel and a production method thereof. The high-conductivity polymer-carbon-based composite aerogel comprises carbon atoms distributed in a flake nano-structure mode and a polymer which is connected with the carbon atoms through covalent bonds; and the polymer comprises a polymer containing at least one carboxyl group anda polymer containing at least one alcoholic group. The polymer-carbon-based composite aerogel is polymer-graphene oxide composite aerogel or polymer-graphene composite aerogel; and the polymer which has at least one carboxyl group is 4-carboxybenzaldehyde and the like, and the polymer which has at least one alcoholic group is polyvinyl alcohol, a polymer which is obtained by conducting hydroxyl modification on poly-p-phenylene, a polymer which is obtained by conducting hydroxyl modification on poly-p-xylylene, or the like. According to the aerogel, pure graphene oxide or graphene is used, by combining the pure graphene oxide or graphene and an intrinsically conductive polymer through the covalent bonds, the conductivity performance is greatly improved, and large-scale industrial productionis benefited.
