Detailed description of the invention
The cross-sectional view of Fig. 1 the utility model；
The outside drawing of Fig. 2 the utility model.
In figure, 1, upper surface；2, bolt hole；3, outer surface；4, lower surface；5, inner surface.
Specific embodiment
To overcome defect existing for existing wear ring, meets real needs, design a kind of pump for liquid salts wear ring (such as Fig. 1, figure
2), including circular body, the outer surface 3 of ontology are L-type structure, and width, which is greater than on the upper surface 1 of lower surface 4, is provided with several spiral shells
Keyhole 2, bolt hole 2 are evenly distributed on the inside of ontology circumference, and ontology is using austenitic stainless steel (OCr17Ni12Mo2N) successively
The integral structure to be formed is cleaned by forging, heat treatment, machine tooling and ultrasonic wave and ion beam bombardment, 1 μm of roughness or so
Inner surface 5 on multi-layer lifting abrasion resistant and corrosion resistant is coated with by electron beam evaporation plating, equipment for Ion Beam Assisted Deposition hard it is compound
Film；The multilayer hard composite membrane is three-decker, successively includes the titanizing coated in 1 μ m-thick on inner surface 5 except interior
(Ti) layer, titanium nitride (TiN) layer of 1 ~ 3 μ m-thick and the silicon nitride (Si of 3 ~ 5 μ m-thicks3N4) layer.When forging, starts light pressure, work as deformation
Amount reach 30% after could weight, when forging should unidirectionally be sent into, avoid repeating to suppress at one, be split with preventing central cross
Line, deflection should be greater than recrystallization critical deformation, and deflection generally should be greater than 12% ~ 20%, require to become in deformation process
Shape is uniform, and to obtain more uniform grain structure, when deformation is compressed using interval, when final forming, is considered as larger shrinking percentage
(1.5 ~ 1.7%), and forging temperature highest furnace temperature overstriking, to 1200 DEG C, forging temperature should be at 850 DEG C.Ontology is heated to solid solution temperature
It spends (1050 ~ 1100 DEG C), then rapid cooling, keeps single-phase high temperature microstructure to be heat-treated at room temperature.Ontology is carried out before plating tight
The ultrasonic cleaning of lattice, oil removing and descale cleaning, are fitted into filming equipment and are cleaned using ion beam bombardment, about very
Clock.The primary effect of icon bombardment cleaning is to remove the foreign particle of substrate surface, thorough exposed true substrate surface atom.
Using special electron beam evaporation plating, equipment for Ion Beam Assisted Deposition plated film, i.e., with the beam bombardment material to be evaporated focused, make
Evaporation material generates thousands of degree high temperature locally to achieve the purpose that evaporate material, while constantly bombarding film table with ion beam
Face makes the counterdiffusion of atom phase and mixing between film base material material, so that film base interfacial stress be made to be minimized, while improving material film base junction
With joint efforts, fine and close coating is obtained.
The utility model has the beneficial effects that selecting austenitic stainless steel (OCr17Ni12Mo2N raw material) are forged as impeller,
OCr17Ni12Mo2N is had in N, improve intensity and does not reduce plasticity, there is very good corrosion resistance, and heat resistance and machinery are special
Property, punching press, the hot-workabilities such as bending are good, no heat treatment hardening phenomenon, cupric and phosphorus content is low, and resistance to corrosion is not better than 304
Become rusty steel；Inner surface is coated with multilayer complex films, improves wear-resistant, anti-oxidant and corrosion resistance, high-efficient and long service life.
Simply changing and replacing for those ordinary skill in the art is all within the protection scope of the utility model.
