Ukusetshenziswa komhloli wobulukhuni

Umhloli wokuqina uyithuluzi lokulinganisa ubulukhuni bezinto zokwakha. Ngokwezinto zokwakha ezahlukene ezilinganiswayo, umhloli wokuqina ungasetshenziswa emikhakheni ehlukene. Ezinye izihloli zokuqina zisetshenziswa embonini yokucubungula imishini, futhi zilinganisa kakhulu ubulukhuni bezinto zensimbi. Njenge: umhloli wokuqina weBrinell, umhloli wokuqina weRockwell, umhloli wokuqina weLeeb, umhloli wokuqina weVickers, umhloli wokuqina we-microhardness, umhloli wokuqina weShore, umhloli wokuqina weWebster njll. Izikali zokusetshenziswa ezithile zalezi zihloli zokuqina zilandelayo:

Umhloli wobulukhuni beBrinell:Isetshenziswa kakhulu ekuhlolweni kobulukhuni bensimbi ehlanganisiwe kanye nensimbi ehlanganisiwe enesakhiwo esingalingani. Ubulukhuni beBrinell bensimbi ehlanganisiwe kanye nensimbi ehlanganisiwe empunga buhambisana kahle nokuhlolwa kokuthamba. Ukuhlolwa kobulukhuni beBrinell kungasetshenziswa futhi ezinsimbini ezingezona insimbi kanye nensimbi ethambile. I-indenter encane yebhola enobubanzi ingalinganisa usayizi omncane nezinto ezincane, futhi ilinganise izitolo zokulungisa ukushisa kanye neminyango yokuhlola ifektri yezimboni ezahlukene zemishini. I-Brinell hardness tester isetshenziswa kakhulu ekuhlolweni kwezinto zokusetshenziswa kanye nemikhiqizo eqediwe kancane. Ngenxa yokugoba okukhulu, ngokuvamile ayisetshenziselwa ukuhlolwa komkhiqizo oqediwe.

 

Umhloli wobulukhuni beRockwell:Hlola izinsimbi ezahlukahlukene zensimbi eziqinile nezingenalo i-ferrous, hlola ubulukhuni bensimbi ecinyiwe, insimbi ecinyiwe neqinisiwe, insimbi eqinisiwe, insimbi eqinile, amapuleti anobukhulu obuhlukahlukene, izinto ze-carbide, izinto ze-powder metallurgy, izembozo ze-thermal spray, ama-castings abandayo, ama-castings angaguquki, ama-aluminium alloys, insimbi ethwala, amapuleti ensimbi aqinile, njll.

Isivivinyo Sokuqina Kokuqina Kwe-Rockwell Esingabonakali:Kusetshenziselwa ukuhlola ubulukhuni bensimbi encane, ipayipi elincane lodonga, insimbi eqinile kanye nezingxenye ezincane, i-alloy eqinile, i-carbide, insimbi eqinile, ishidi eliqinile, insimbi eqinile, insimbi ecinyiwe neqinisiwe, insimbi ephothiweyo ebandayo, insimbi ephothiweyo, i-aluminium, ithusi, i-magnesium kanye nezinye izinsimbi ze-alloy.

 

Isihloli sobulukhuni be-Vickers: linganisa izingxenye ezincane, amapuleti ensimbi amancane, ama-foil ensimbi, amashidi e-IC, izintambo, izendlalelo eziqinile ezincane, izendlalelo ezifakwe ngogesi, ingilazi, ubucwebe kanye nobumba, izinsimbi ze-ferrous, izinsimbi ezingezona i-ferrous, amashidi e-IC, izembozo zomphezulu, izinsimbi ezi-laminated; ingilazi, izinto zobumba, i-agate, amatshe ayigugu, njll.; ukuhlolwa kokujula kanye nokuqina kwe-gradient kwezingqimba ezifakwe i-carbon kanye nezendlalelo eziqinile zokucima. Ukucubungula ihadiwe, imboni ye-elekthronikhi, izesekeli zesikhunta, imboni yamawashi.

 

I-Knoopumhloli wobulukhuni:isetshenziswa kabanzi ukukala ubulukhuni bezinhlobo ezincane nezincane, izembozo zokungena ebusweni kanye nezinye izinhlobo, kanye nokukala ubulukhuni be-Knoop bezinto ezibuthakathaka neziqinile njengengilazi, izinto zobumba, i-agate, amatshe ayigugu okwenziwa, njll., ububanzi obusebenzayo: ukwelashwa kokushisa, i-carburization, ungqimba lokuqinisa olucimayo, isembozo sobuso, insimbi, izinsimbi ezingezona i-ferrous kanye nezingxenye ezincane nezincane, njll.

 

Umhloli wobulukhuni beLeeb:insimbi kanye nensimbi ehlanganisiwe, insimbi yethuluzi le-alloy, insimbi ehlanganisiwe empunga, insimbi ehlanganisiwe, i-aluminium alloy ehlanganisiwe, i-copper-zinc alloy (ithusi), i-copper-tin alloy (ithusi), ithusi elihlanzekile, insimbi eyakhiwe, insimbi yekhabhoni, insimbi ye-chrome, insimbi ye-chrome-vanadium, insimbi ye-chrome-nickel, insimbi ye-chrome-molybdenum, insimbi ye-chrome-manganese-silicon, insimbi enamandla kakhulu, insimbi engagqwali, njll.

 

Shinsimbiumhloli wobulukhuni:Isetshenziswa kakhulu ukukala ubulukhuni bepulasitiki ethambile kanye nerabha yokuqina evamile, njengerabha ethambile, irabha yokwenziwa, amarola erabha okunyathelisa, ama-elastomer e-thermoplastic, isikhumba, njll. Isetshenziswa kabanzi embonini yepulasitiki, embonini yerabha kanye neminye imboni yamakhemikhali, kufaka phakathi ubulukhuni bepulasitiki eqinile kanye nerabha eqinile, njenge-thermoplastic hard resins, izinto zaphansi, amabhola e-bowling, njll. Ifaneleka kakhulu ekulinganisweni kobulukhuni berabha kanye nemikhiqizo eqediwe yepulasitiki endaweni.
