Embodiment 1

[0039] In this embodiment, the workpiece is a turbine rotor blade. Place the intake side of the two turbine working blades inward in the positioning box, and place it on the first floor of the equipment. After the coating process is carried out according to the process parameters in the present invention, the outer surface of the airfoil and the upper surface of the edge plate are coated, and the turbine working blade is obtained with effective protection for the tenons.

[0040] The specific usage of tooling is as follows:

[0041] Step 1, cleaning: clean the turbine working blades and tooling with acetone, and prepare for clamping. Cleaning is to prevent the parts from being polluted and affecting the adhesion of the coating.

[0042] Step 2, clamping: put the tenons of the turbine working blades into the positioning box, and connect them into a string through the hook.

[0043] Step 3, apply the coating, the specific process is:

[0044] Furnace loading: Connect the str...

Embodiment 3

[0065] The tooling of this embodiment can effectively ensure that the outer surface of the blade body and the upper surface of the edge plate are coated with a uniform thickness, and the tenon needs to be protected.

[0066] In this embodiment, the workpiece is a turbine rotor blade. Place the intake side of the two turbine working blades inward in the positioning box, and place it on the third floor of the equipment. After the coating treatment is carried out according to the corresponding process parameters, the outer surface of the airfoil and the upper surface of the edge plate are coated, and the working blade of the turbine is obtained, and the tenons are effectively protected.

[0067] The specific usage of the tooling is as follows:

[0068] Step 1, cleaning: clean the turbine working blades and tooling with acetone, and prepare for clamping. Cleaning is to prevent the parts from being polluted and affecting the adhesion of the coating.

[0069] Step 2, clamping: pu...

Abstract

The invention discloses a tool for depositing a coating on multi-arc ion plating equipment and a usage method thereof. The tool comprises a pull bar, positioning boxes, a connection plate and suspension hooks; two ends of the pull bar are provided with the suspension hooks, the bottom end of the pull bar is provided with the connection plate, and the positioning boxes used for putting turbine blades are arranged on the connection plate at two sides of the pull bar. The provided tool is simple in structure, convenient for maintenance, novel in design and convenient and rapid for mounting and dismounting. The tool protects a tenon, and also guarantees the uniformity of the thickness of the coating on various areas of the turbine blades and a margin plate upper surface, in other words, the usage performance of the coating is guaranteed. The tool protects the tenon through a physical shielding principle, the blade bodies simultaneous realize revolution and rotation in the coating process, two blades are arranged in a parallel way, and all blades are uniformly coated to form coatings by controlling the distance between the turbine working blades to not generate the physical shielding phenomenon.

Description

technical field [0001] The invention belongs to the physical vapor deposition technology, and in particular relates to a coating tooling used for multi-arc ion plating equipment and a use method thereof. Background technique [0002] Multi-arc ion plating technology is a kind of ion plating technology using cathodic arc evaporation source, which is used for coating MCrAlY on turbine blades and TiN coating on compressor blades. At present, there are many technical difficulties to be overcome when applying multi-arc ion plating equipment to coating deposition. First of all, the effective size of the equipment is small, the alloy ingot is expensive, and the deposition rate is low, which leads to problems such as long processing cycle and high cost of parts. Secondly, when using multi-arc ion plating technology to deposit coatings on the surface of turbine working blades, the outer surface of the blade body and the surface of the edge plate are required to be coated with unifor...
