Embodiment Construction

[0053] The present invention is described in further detail below in conjunction with accompanying drawing:

[0054] The invention discloses a supporting device for gas phase deposition on the full channel surface of a guide vane and its application method; the device comprises: a connecting rod 1, a through hole 2, an L-shaped connecting plate 3, a self-rotating bearing device 4, and a protective box for an outer edge plate 5. Support nut 6, inner edge plate protection box 7, guide vane 8 and connecting screw rod 9.

[0055] like figure 1 As shown, one end of the connecting rod 1 is provided with a through hole 2 for connecting with the equipment rotating shaft 11, and the other end uses a nut to fix the connecting rod 1 and the L-shaped connecting plate 3; the L-shaped connecting plate 3 is provided with a self-rotation bearing device 4. The rotation bearing device 4 is connected with the protective box 5 of the outer edge plate, and the protective box 5 of the outer edge p...

Abstract

The invention discloses a support device for guiding vane full flowpath face vapour deposition and an application method thereof. A clamping device is connected with a rotating shaft through a connecting plate and an L-shaped connecting plate. A guiding vane is mounted inside the clamping device in a clamping manner. The L-shaped is in an L shape, thus, the axis direction of the guiding vane is perpendicular to the axis direction of the rotating shaft; in the coating process, the guiding vane can substantially rotate around the axis direction of the rotating shaft; on the premise that the vanebody surface ceramic coating bonding strength and the columnar crystal structure are guaranteed, the listrium surface bonding strength is greatly improved; an uniform columnar crystal structure is formed; thus, the guiding vane full flowpath face is coated with thermal barrier coating; the heat-resistance temperature of the guiding vane and working stability are greatly improved. The support device is simple in structure; the number of the components is small; product is easy to machine and dismount and mount; and matching design can be conducted on a tool according to the guiding vane structure.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of engine guide vane manufacturing, in particular to a support device for vapor deposition on the full channel surface of a guide vane and a method for using the same. [0003] 【Background technique】 [0004] At present, electron beam physical vapor deposition (EB-PVD for short) has the advantages of high bonding strength between the coating and the substrate, the columnar grain structure can be obtained, the chemical composition of the coating is easy to precisely control, and the coating has a long service life. It has been widely used in multi-machine The preparation and processing of high-temperature protective coatings for engine turbine blades significantly improves the high-temperature oxidation resistance, corrosion resistance, and heat insulation performance of turbine blades, and prolongs the working life of the engine. [0005] EB-PVD technology uses an electron beam gun to heat the part when deposi...
