The problem was that it was weak in mechanical strength. Furthermore, although composite materials have advantages such as being lightweight and easy to install, they cannot improve the mechanical strength of ceramics.

利用できる。(Example) The following describes an example of the dewatering blade as an example of the present invention. Fig. 1 is a sectional view of a wire dewatering section using the dehydrating blade of the present invention, and 1 in the figure is a flat bar. This is a base material for thermal spraying, and 2 is a frame having a U-shaped cross section.
Both the flat bar 1 and the frame 2 are made of thin plates of an alloy material, such as austenitic stainless steel, which has excellent corrosion resistance and is less deformed by thermal spraying, etc., and the two are bonded and integrated using a solution. In the illustrated embodiment, both are integrated by spot welding 3. In addition, seam welding, laser welding, etc. can be used.

めに、３〜4S程度の研磨仕上げがなされる。 After blasting, the entire surface of the flat bar 1 is coated with ceramic such as alumina (Al 2 O 3 ) by plasma spraying to form a ceramic sprayed layer. The sharp edge portion 8 of the flat bar 1 is also formed of a thermally sprayed coating. By spraying the sharp edge portion 8 to the back surface, the peeling resistance of the sprayed coating is improved. Furthermore, after thermal spraying, the film is sealed with epoxy resin or the like. The sprayed surface is polished to a level of about 3 to 4 S in order to prevent wear and damage to the plastic wire 9 or to improve water flow.

A core 4 made of synthetic resin is incorporated inside the frame, and a substantially T-shaped groove 5 is formed on the bottom surface of the core 4 to be attached to the main body side consisting of a T-bar 7. Note that since the T-bar on the main body side is generally made of metal, using a synthetic resin material for the core has the advantage of preventing seizure and can keep the weight of the entire blade low. The plastic wire 9 advances while sliding in the direction of the arrow shown in the figure over the ceramic sprayed layer 6 on the dewatering blade of this embodiment having such a structure. At this time, dehydration is carried out through the mesh of the plastic wire 9. Most of the liquid is dehydrated at the sharp edge part 8 of the flat bar 1, and this liquid hits the side surface of the frame 2 and flows down to the bottom, as shown by the thick arrow in FIG.

の重量を低く押えることができるものである。(Effects of the invention) As explained above in detail, the sliding member for a paper machine according to the invention uses a thin plate of an alloy material with excellent corrosion resistance, such as austenitic stainless steel, as a base material, and Since the film is formed by plasma spraying an alumina-based material on the material, a sliding member that is lightweight, has high impact resistance, and has wear resistance can be obtained. Therefore, it is possible to extend the life of the wire, prevent pulp residue from adhering to the surface of the member, and because a thin plate of alloy material is used, it is easy to form an integral structure member that matches the width of the paper machine. As a result, good paper can be produced. Furthermore, compared to blades made of sintered ceramics or synthetic resins, since the base material is metal, the mechanical strength is improved and it can be manufactured at a relatively low cost. In addition, since the T-bar on the main body side is generally made of metal, if a synthetic resin material is used as the core,
This has the advantage of preventing seizure and can keep the weight of the entire blade low.
