In order to reach the purpose of this utility model, technical scheme is as follows：
A kind of oil cylinder, piston rod matrix material, it is characterised in that be provided with plasmasphere in substrate material surface, it is described etc.
The surface of sheath is provided with hard alloy layer.
Preferably, the thickness of the plasmasphere is 200~400mm, and the thickness of the hard alloy layer is 50~80mm.
Preferably, there is the oil sump for caving inward on the surface of the hard alloy layer.
A kind of oil cylinder, piston rod matrix material and preparation method thereof, it is characterised in that including step：
1), plasma quenching：Quenching matrix is formed plasma quenching is carried out to substrate material surface, the depth of quenching is 50
μm~400 μm, in quenching process, quenching matrix surface is formed the groove for caving inward；
2), quenching matrix surface treatment：The matrix that will quench be impregnated in hard alloy, and hard alloy is made with catalytic reduction method
Quenching matrix surface is adsorbed in, adding to uniform temperature with industrial sintering process makes sintering cemented carbide strong bonded in quenching matrix
On, then honing is to required size.
Preferably, according to weight fraction meter, the hard alloy includes：
The utility model has the advantage that：
New technology does not use plating but by techniques such as plasma hard alloy, and the cylinder piston rod produced has super
Strong hardness (HV1037) and rotproofness (salt mist experiment more than 200 hours), have filled up the sky of domestic and international cylinder piston rod manufacture
In vain.There are many Mini-type Grids on treated surface and have oil sump, with good lubrication, largely prolongs
The service life of part is grown.

Fig. 2 is the cross section structure schematic diagram of matrix material of the utility model on oil cylinder；
Fig. 3 is the partial enlarged drawing of Fig. 1；
Net distribution figure when Fig. 4 is for quenching.
Specific embodiment
The utility model is further described with reference to embodiment, but protection domain of the present utility model not only office
It is limited to embodiment.
With reference to shown in Fig. 1 and Fig. 2, a kind of oil cylinder, piston rod matrix material are provided with plasmasphere on the surface of matrix material 1
2, the surface of the plasmasphere 2 is provided with hard alloy layer 3.The thickness of plasmasphere 2 is 200~400mm, the hard alloy
The thickness of layer 3 is 30mm or so.
With reference to shown in Fig. 3, the oil sump 4 for caving inward is formd on the surface of hard alloy layer 3.Machine oil can be held in oil
In pond 4, therefore good lubrication can be played, largely extend the service life of part.
A kind of oil cylinder, piston rod matrix material and preparation method thereof, it is characterised in that including step：
1), plasma quenching：Quenching matrix is formed plasma quenching is carried out to substrate material surface, the depth of quenching is 50
μm~400 μm, preferably 200 μm~300 μm, during quenching, can be to the four corner of substrate material surface or part range
Carry out plasma quenching；
Preferably, matrix surface is quenched using web form, as shown in figure 4, the meshy arrangement of quenching point 10, not complete
Matrix surface is lived in all standing, and after quenching, the matrix surface at quenching point 10 just generates depression.
2), quenching matrix surface treatment：The matrix that will quench be impregnated in hard alloy, and hard alloy is made with catalytic reduction method
Quenching matrix surface is adsorbed in, adding to uniform temperature with industrial sintering process makes sintering cemented carbide strong bonded in quenching matrix
On, then honing is to required size.
Because matrix surface forms depression after quenching, after dipping hard alloy, in the recess of hard alloy layer 3
Oil sump 4 is formd with regard to corresponding.
According to weight fraction meter, the hard alloy includes：
The shape of oil sump arrangement can have many kinds, such as grid-shaped, screw thread shape, linear etc..It should be noted that oily
The formation in pond is determined by quenching process, in quick cooling procedure after the heating, quenching matrix table is made by applying external force
Face forms the groove for caving inward, and then when being surface-treated to quenching matrix, hard alloy is also according to quenching matrix
Shape and adsorb and be consolidated in quenching matrix surface, ultimately form the oil sump that can store machine oil.
Final material obtained in the present invention is carried out into performance contrast test, testing standard with reference to GB/T 4340.1-2009,
GB/T 6462-2005/ISO 1463：:2003rd, GB/T 1012502012, it is as a result as shown in the table,
Wherein salt mist experiment condition is：Through concentration (50+5) g/L (chemical pure sodium chloride+distilled water), pH value is 6.5-7.2
Solution in, nozzle air pressure：70KPa, salt fog cabinet temperature (35 ± 2) DEG C, saturation air temperature (45 ± 2) DEG C, continuous spray
Mist 200 hours, 4 samples are showed no and get rusty.
From test result as can be seen that matrix material obtained in the utility model, its hardness and smog experimental performance much
More than the performance of domestic existing product, Japan and American-European standard have been even more than.
Finally it should be noted that：Above example is only used to illustrate the utility model and not limit the utility model and retouched
The technical scheme stated, therefore, although this specification the utility model is had been carried out with reference to each above-mentioned embodiment it is detailed
Illustrate, but, it will be understood by those within the art that, still the utility model can be modified or equally replaced
