Specific embodiment
For the ease of the understanding of those skilled in the art, the present invention is made further with reference to embodiment and accompanying drawing It is bright, it has to be noted that the content that following implementation methods are referred to not limitation of the invention.
The equipment that preparing wear resistant corrosion resistant nuclear grade stainless steel of the present invention need to use has multifunction ion to inject enhancing Depositing device, LD-3 type ion-nitriding furnaces, drying box, the note nitrogen and nitriding that these equipment are commonly used for those skilled in the art set Standby, test material used is core 304 stainless steels of level, chemical composition（In terms of mass fraction）For：C≤0.07%, Si≤1.0%, Mn ≤ 2.0%, Cr：17.0% ~ 19.0%, Ni：8.0% ~ 12.0%, P≤0.035%, S≤0.03%, Fe surpluses.Specific preparation process is such as Under：
The pretreatment of the first step, nuclear grade stainless steel
1）Polishing：With 200#SiC silicon carbide papers polish, remove surface cutting cut and greasy dirt, then successively with 400#, 600#, 800#, 1000# and 1200#SiC silicon carbide paper carry out mechanical grinding to nuclear grade stainless steel surface；
2）Polishing：Nylon polishing cloth and granularity are that 1.5 μm of diamond polishing cream is mechanically polished to each sample facet, table Surface roughness reaches Ra≤0.05um；
3）Cleaning：Ultrasonic wave cleaning is carried out in the mixed solution of acetone soln, distilled water and alcohol successively, the time is about 15 points Clock；
4）Dry：Nuclear grade stainless steel after cleaning is put such as cold air drying in drying box, is sealed stand-by.
Second step, nitrogen implantation：Set multifunction ion injection enhanced deposition is put into by the nuclear grade stainless steel of pretreatment Standby to carry out note nitrogen, ion implantation energy is 45KV, implantation temperature is controlled at 300-400 DEG C, and implantation dosage is 6 × 1017ions/ cm2-12×1017ions/cm2；
3rd step, glow discharge nitriding：The nuclear grade stainless steel noted after nitrogen is put into carries out Nitrizing Treatment in ion-nitriding furnace, set in stove Temperature is 450-490 DEG C, and nitriding pressure is 330pa, N2:H2It is 3：1, nitriding time is 15-19h.
The nuclear grade stainless steel surface treated using the above method can produce the uniform composite nitride layer of a layer thickness, the nitrogen Changing layer has good wearability, corrosion resistance and the bond strength with matrix.Nitridation thickness >=the 100um, case hardness is remote It is much better than existing glow discharge nitriding；XRD analysis display composite nitride layer possesses the γ N phases of single, wideization（Referring to）, thus with good Good corrosion resistance；Electrochemical corrosion test shows that the nuclear grade stainless steel corrosion potential after treatment is improved, and corrosion current increases Slowly, the nuclear grade stainless steel of the more traditional Nitrizing Treatment of rate of corrosion is greatly lowered；Scratch test display composite nitride layer load is reachable More than 60N, and scratching edge occurs without composite nitride layer peeling.
For the wear resistant corrosion resistant nuclear grade stainless steel that the checking present invention is provided notes nitrogen, nitrided surface handling process relative to existing The improvement amplitude of the combination property of nuclear grade stainless steel afterwards, applicant has done 8 groups of examinations using existing process and above-mentioned preparation method Test.Wherein, above-mentioned preparation method is totally five groups of embodiment 1-5；Nuclear grade stainless steel without any treatment is comparative example 1；By existing There is technique to make Nitrizing Treatment for comparative example 2；Make note nitrogen by existing process and be processed as comparative example 3.
The difference of embodiment 1-5 essentially consists in and the partial parameters of second step and the 3rd step is adjusted, so that Generate the slightly discrepant different nitration cases of property indices.The specific processing parameter of each embodiment and comparative example see the table below 1 It is shown.
