Description
Technical field
A kind of method the present invention relates to plating tool and using the plating tool.
Background technology
High-pressure turbine blade is in the rough circumstances of combustion chamber rear end, in high temperature, such as 1300 degrees Celsius with
Upper running, quick rotation from high temperature gas flow to obtain energy.The high operation temperature so that high-pressure turbine blade is easy
It fails because of corrosion.Therefore, how to improve its heat-resisting ability is absorbed in always to the research of turbo blade.With operation temperature
The raising of degree, it is inadequate by the intrinsic high temperature resistance of blade metal material, and need to improve it using protective coating
Heat-and corrosion-resistant performance.
Usually have on blade on the surface that the gas of very high temperature flows through coated with ceramic heat-barrier coating (thermal
Barrier coating, TBC).For traditional high-pressure turbine blade, blade listrium region is generally coated with ceramic heat
Barrier coating, and other regions, such as the cavity region between listrium and tenon root, be typically do not have it is cated because the cavity region
On operating temperature it is lower than the operating temperature on blade and listrium region, do not have cated high temperature alloy that can be resistant to described opposite
Relatively low operating temperature.However, the growth of the working time with engine, burn into from hot gas and from gas
Present in corrosive elements such as sulphur corrosion etc., may result in the defects of micro-crack occurs in the cavity region.
It has now been found that, the coating containing chromium is adapted to increase cavity region between high-pressure turbine blade supramarginal plate and tenon root
Corrosion resistance.Plating is a kind of cost effective method for being widely used for providing coating on workpiece.However, due to high-pressure turbine leaf
There are sharp recess or projective structure on the cavity region of piece, be difficult to be obtained uniformly in the entire cavity region in electroplating process
Electric field distribution, so as to be difficult to obtain uniform coating layer thickness in the entire cavity region.Therefore, being somebody's turn to do in high-pressure turbine blade
Cavity region, which obtains one layer of Chromium coating for meeting thickness uniformity requirement, has larger difficulty.
