Ezinqubweni zokuqinisa ubuso bensimbi ezifana nokufaka i-carburizing, ukufaka i-nitriding kanye nokucima i-induction, ukuhlolwa kobulukhuni be-core kanye nokujula kwesendlalelo esiqinile, kanye nokukhubazeka ezinqubweni zokwelapha ukushisa, kuzothinta izakhiwo zemishini zemikhiqizo. Sisebenzisa umhloli wobulukhuni be-micro Vickers ukuqedela yonke inqubo yokuhlola nokulawula ukujula kwesendlalelo esiqinile, okuyisibonakaliso esiyinhloko sokulawula ikhwalithi.
1. Ukulungiselela Isampula
· Khetha ingxenye yokuhlola noma isampula ejwayelekile bese usika ingxenye evundlile ukuqinisekisa ukuthi indawo evivinyiwe iyisicaba, ayinazo iziphazamiso futhi ayinazo iziphazamiso.
· Gaya bese upholisha ingxenye ephambene ukuze ususe ungqimba lwe-oxide olungaphezulu kanye namamaki omshini.
· Qopha njengoba kudingeka ngokwezindinganiso ezifanele (uma kudingeka) ukuze uhlukanise ngokucacile ungqimba olungaphezulu nokwakheka okuyinhloko.
2. Ukuhlolwa kobulukhuni obuyinhloko
Sisebenzisa isihloli sokuqina kwe-Model MHV-1000AT micro Vickers ukuze siqedele yonke inqubo yokuhlola.
· Beka isampula ngokuphephile esiteji sesivivinyo sokuqina kwe-Micro Vickers bese uyivumelanisa nendawo eyinhloko (kude nongqimba oluqinisiwe olungaphezulu).
· Setha amandla okuhlola (ngokuvamile i-HV1.0) kanye nesikhathi sokuhlala, bese uqinisekisa ukuthi imishini ilinganiswe kahle.
· Khetha amaphuzu okulinganisa afanayo angu-3 kuya kwangu-5 enkabeni, ugweme amaphutha afana nokuvuleka, imigodi yomoya kanye nokufakiwe.
· Qala ukulinganisa; amanani obulukhuni afundwa ngokuzenzakalelayo, futhi inani elimaphakathi lithathwa njengomphumela wokugcina wobulukhuni obuyinhloko.
3. Ukuhlolwa Kokujula Kwezingqimba Eziqinile
· Hlela amaphuzu okuhlola ngezikhawu ezilinganayo emugqeni oqondile ukusuka ebusweni kuya enkabeni, bese usetha ibanga lesinyathelo ngokuhambisana nezindinganiso ezifanele (ngokuvamile 10–50 μm).
· Kala iphuzu lobulukhuni ngephuzu, bese uqopha inani lobulukhuni kanye nokujula okuhambisanayo kwendawo ngayinye.
· Qhubeka nokulinganisa kuze kube yilapho ubulukhuni buzinzile ngaphansi kwenani elibalulekile, bese umisa ukuhlolwa.
4. Ukwahlulela Ukujula Kwezingqimba Eziqinile (CHD) Okusebenzayo
· Nquma inani lokuqina okubucayi ngokuhambisana nezindinganiso ezihambisanayo (isb., GB/T 9450).
· Thola indawo lapho ubulukhuni buqala khona ukwehla bube yinani elibalulekile; lokhu kujula kuchazwa njengokujula kwengqimba eqinile okusebenzayo.
5. Ukucubungula Nokubika Idatha
· Hlela ijika lokusabalalisa ubulukhuni ngokujula njenge-axis evundlile kanye nobulukhuni njenge-axis eqondile ukuze ubonise i-gradient yobulukhuni.
· Hlela idatha ehlanganisa ubulukhuni obuyinhloko, ukujula kwezingqimba eziqinisiwe kanye nejika lobunzima ukuze ukhiqize umbiko wokuhlola.
Ukuhlolwa kobulukhuni nokujula okungenhla kwenziwa yi
Umshini wokusika we-metallographic we-Q-80Z
Umshini wokugaya nokupholisha we-metallogtaphic ozenzakalelayo we-MP-2000
Isihloli sokuqina kwe-MHV-1000AT micro Vickers
Uma ufuna ukwazi okwengeziwe ngabo sicela ucindezele ngokuchofoza okuhambisanayo entweni yomkhiqizo.
