Ngoba akwenzi luthoUkukhokhiswa kwensimbizivame ukusetshenziswa endaweni esemqoka yomshini, ngakho-ke ikhwalithi yangaphakathi ye-stainlessUkukhokhiswa kwensimbikubaluleke kakhulu. Ngoba ikhwalithi yangaphakathi ye-stainlessUkukhokhiswa kwensimbiAyikwazi ukuhlolwa yindlela enembile, ngakho-ke kusetshenziswa ukuhlolwa okukhethekile ngokomzimba nangamakhemikhali ukuhlola.

Okokuqala, izakhiwo zemishini zokuthikhiswa
Izakhiwo zemishini zeukuthethelelwazinqunywa ngokuya ngezidingo zomkhiqizo. Izindlela zokuhlola zihlukaniswe ngobunzima bokuhlola, ukuhlolwa okuthe xaxa, ukuhlolwa komthelela nokuhlolwa kokukhathala.
1. Ukuhlolwa kobulukhuni
Ubulukhuni buwukumelana nokuchazwa kwezinto ezibonakalayo, kuyinkomba ekala ngokuthile kwensimbi kanzima. Ubulukhuni kanye nezinye izakhiwo zemishini zinobudlelwano obuthile bangaphakathi, ngakho-ke ezinye izakhiwo zemishini zezinto zokwakha zingalinganiswa ngenani lokulukhuni. Ukuhlolwa kwe-Hardnessness akudingi ukulungiselela amasampula akhethekile, futhi ngeke kubhubhise i-specimen, ngakho-ke ukuvivinya ukuqina kuvame ukusetshenziswa kakhulu ekukhiqizweni kwendlela yokuhlola impahla yempahla.
Izindlela zokuhlola izinkambiso ezivame ukusetshenziswa namanani ahlukene yilezi: I-Brinell Hardness (HB), i-Rocwell Hardness (HRC), Ubulukhuni be-VS), Ubulukhuni bama-HORE, kanye noMhloli wobulukhuni obuhambisanayo.
2. Ukuhlolwa kwesikhashana
Ngokusebenzisa umthwalo othe xaxa othangothini lwesimo esithile ngomshini we-tensile, ukucindezelwa okulinganayo, iphuzu lesivuno, amandla okuvuselela, ukuncishiswa kanye nokuncishiswa kwesigaba sezinto zensimbi zilinganiswa.
3. Ukuhlolwa komthelela
Ukuqina kwethonya lensimbi kutholwe ngokusebenzisa i-pendulum enesivinini esikhulu ukufaka umthelela ocingweni nge-notch.
4. Ukuhlolwa Kokukhathala
Umkhawulo wokukhathala kanye nokukhathala amandla wensimbi angalinganiswa ngemuva kokucindezela okuphindaphindwayo noma okuhlukile.
Ukuhlolwa okubili, okungekho okulimazayo kokwakha
Ukuhlolwa okungahambi kahle kungahlukaniswa ekuhlolweni kwe-radiographic, ukuhlolwa kwe-ultrasonic, ukuhlolwa kwamandla kazibuthe, ukuhlolwa kwe-EPAGE kanye nokuhlolwa kwamanje kwangaphambi kwesikhathi. Ukuthethelelwa kuvame ukusetshenziswa ekuhlolweni kwe-ultrasonic kanye nokuhlolwa kwezinhlayiyana kazibuthe.
1. Ukuhlolwa kwe-Ultrasonic
I-Ultrasonic Wave (imvamisa imvamisa ikhulu kune-20000hz) izokhombisa futhi iphinde ivume isikhonkwane sezinto ezihlukile. Ngakho-ke, uma kukhona iziphambeko zezinto ezihlukile kwezinto eziqinile, ukuboniswa kwe-wave kanye ne-attenciation kuzokwenziwa. Ukuba khona kweziphambeko kungahlulelwa ngama-waveform amasiginali.
Okwesikhulu naphakathiukuthethelelwa, ukuhlolwa kwe-ultrasonic kungenye yezindlela ezibalulekile zokuhlolwa okungathandeki.
2. I-Magnetic Particle (
Amaphutha anjengokuqhekeka, ama-pores kanye nokufakwa okungathandeki futhi eduze kobuso obukhokhiswayo kungahlolwa ngokuhlolwa kwezinhlayiyana kazibuthe. Ngenxa yemishini yayo elula, ukusebenza okulula kanye nokuzwela okuphezulu, le ndlela ivame ukusetshenziselwa ukuvivinya izizathu zokufa ezincane naphakathi eziphakathi nendawo ezikhiqizwe ngamanani amakhulu.
Amathathu, Amandla Amandla Amandla Ne-Fracture
Ukuhlolwa kwamandla okuphansi isampula ngemuva kwenani elithile lokucutshungulwa, bese ngeso elinqunu izikhathi eziyi-10 ~ 30 Ingilazi ekhulisayo ukubheka isampula, ukuze ithole iziphambeko zokukholelwa kwesampula. Hlanganisa uDendir, uDendrite, okhululekile, uNaphthalene, ukuqhekeka kwamatshe nezinye iziphambeko kungahlolwa ngokusika amasampula we-wafer ne-eacing. Ukuze ubone ukwahlukaniswa, ikakhulukazi ukusatshalaliswa okungalingani kwe-sulfide, kusetshenziswa indlela yokuphrinta ye-sulfur.
Ezine, ukuhlolwa kwamandla aphezulu
Ukukhokhiswa kwensimbi okungenasici kuzokwenziwa ngesampula ethile ngaphansi kwesibonakhulu ukubheka izikhonzi zangaphakathi (noma ukuqhekeka) esimweni senhlangano noma izinkinga eziyi-microscopic. Isakhiwo sangaphakathi kanye nokusatshalaliswa kwe-inclusions kwecala kungabhekwa ngokusika isampula ende. Iziphetho ezingaphezulu njenge-decorruburization, izingqimba ezigobile, ezibunjiwe kanye nezinkambiso nezinkambiso zingahlolwa ngokusika amasampula aguqukayo.
