Layer, significantly improves wear-resisting, anti-corrosion, heat-resisting, anti-oxidant and electrical characteristic the process of substrate surface, changes so as to reach surface
Property or the purpose of reparation, had both met the requirement to material surface particular characteristic, and had saved cost again；With built-up welding, spraying, plating
With gas phase sedimentary facies ratio, there is laser melting coating small dilution factor, dense structure, coating and matrix to be combined, be adapted to cladding material it is more,
The features such as granularity and big changes of contents, therefore laser melting and coating technique application prospect is very wide.
Axle journal is usually to be used for installing the place of bearing on axle, and one section of axle of same diameter or diameter be not etc. but shape on spindle
Into outer round surface be uniformly continuous the face of cylinder, outer round surface must be uniformly continuous, it is impossible to have the shaft shoulder or groove to disconnect.
In the prior art, axle journal tends to wear, such as the axle journal of compressor, because the rotary speed of compressor can be big
45000r/min, so compressor axle journal easily wears；Tradition is repaired and uses brush-plating technique, because coating and matrix can not
Accomplish metallurgical binding, coating is easily peeling during compressor high speed rotational operation, causes security incident.
Therefore, now provide a kind of anti-wear performance good laser melting coating compressorshaft.
Utility model content
Therefore, now providing a kind of laser melting coating compressorshaft, laser melting coating compressorshaft of the present utility model, it includes pressure
Mechanism of qi axle matrix, in addition to laser cladding layer, the laser cladding layer covering are molded over the axle journal of the compressorshaft matrix

The laser cladding layer in a ring, and the axial length of the laser cladding layer be equal to the axle journal length.
Axle journal and/or rear shaft neck before the axle journal is set to.
The laser cladding layer include by cladding powder laser melting coating effect under with the preceding axle journal/rear shaft neck
The cladding layer of the molten solidifying formation in outer surface.
The laser melting coating is set to presetting system or synchronous mode laser melting coating.
The cladding powder is set to high chromium nickel fe-based self-fluxing alloy powder.
The preceding axle journal/rear shaft neck is set to carry out the axle journal after acetone cleaning.
The thickness of the laser cladding layer is not less than 0.5mm.
Above-mentioned technical proposal of the present utility model has advantages below compared with prior art：
Covered in the utility model, at the axle journal of the compressorshaft matrix and form the laser cladding layer, also
It is to say, Laser Cladding Treatment has all been carried out at the axle journal of the compressorshaft matrix so that all swashs formed with described its outer surface
Light cladding layer, so as to improve, the axle journal of the compressorshaft matrix is wear-resisting, anti-corrosion, heat-resisting, anti-oxidant and electrical characteristic
Etc. performance；So that the axle journal of the compressorshaft matrix has good anti-wear performance, the compressorshaft base is improved
The service life of body, while also reduce the probability of security incident generation.
Brief description of the drawings
In order that content of the present utility model is more likely to be clearly understood, below according to specific implementation of the present utility model
Example and with reference to accompanying drawing, is described in further detail to the utility model, wherein
Fig. 1 is laser melting coating compressorshaft schematic diagram described in the utility model；
Fig. 2 is another schematic diagram of laser melting coating compressorshaft described in the utility model；
Reference is expressed as in figure：1- compressorshaft matrixes,；2- laser cladding layers；Axle journal before 3-；4- rear shaft necks.
Embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.It should be appreciated that herein
Described embodiment is merely to illustrate and explained the utility model, is not limited to the utility model.
As illustrated in fig. 1 and 2, the laser melting coating compressorshaft of the present embodiment, it includes compressorshaft matrix 1, in addition to swashs
