Ukuhlolwa kobunzima kwamathuluzi wokusika. Ukulawulwa kweKhwama kwezezimali kubulukhuni be-coating kanye nezinto zokwakha amapuleti amancanyana. Izici ④ nezinzuzo: Ukunemba okuphezulu kakhulu: Ngenxa yokusetshenziswa kwezimali zedayimane, imiphumela yokuhlola ibe nokuphindaphindwa okuphezulu nokunemba. · I-Proversatility: Uyakwazi ukuhlola izinto zokwakha izinhlobonhlobo namasayizi ahlukahlukene, kufaka phakathi amapuleti amancanyana kanye nezingubo zokugqoka. Amanothi noma ukulinganiselwa: Imikhawulo yezinto ezibonakalayo: ayilungele izinto ezithambile kakhulu ngoba i-indenter ingacindezela ngaphezulu kwesampula, okuholela emiphumeleni yokulinganisa engalungile. Ukulondolozwa Kwemishini: Imishini yokuhlola idinga ukulinganiswa futhi igcinwe njalo ukuqinisekisa ukunemba kokulinganisa nokuqina.
(2) HRB
Indlela yokuhlola kanye nesimiso sokuhlolwa: Izinhlobo ezisetshenziswayo zezinto ezibonakalayo: ③ Izimo zesicelo ezijwayelekile: · Ukulawulwa kwekhwalithi kwamashidi wensimbi namapayipi. Ukuhlolwa kobunzima kwezinsimbi ezingezona ze-ferrous kanye nama-alloys. Ukuhlolwa kwezinto ezibonakalayo ekwakhiweni nasezimbonini zezimoto. Izici nezinzuzo: Ukuhlolwa okulula: Inqubo yokuhlola ilula futhi iyashesha, ilungele ukuhlolwa okusheshayo emugqeni wokukhiqiza. Imiphumela Ezinzile: Ngenxa yokusetshenziswa kwe-Indenter yensimbi yensimbi, imiphumela yokuhlola inokuqina okuhle nokuphindaphindwa. Amanothi noma ukulinganiselwa: · Ukulungiswa kwesampula: Ingaphezulu lesampuli lidinga ukuba bushelelezi futhi lifule · Harngenedness Range Limitation: Ayisebenzi izinto ezinzima kakhulu noma ezithambile kakhulu, ngoba i-indenter kungenzeka ingakwazi ukukala ubulukhuni balezi zinto. Ukulondolozwa kwemishini: Imishini yokuhlola idinga ukulinganiswa futhi igcinwe njalo ukuqinisekisa ukunemba nokwethenjwa kwesilinganiso.
(3) HRC
Indlela yokuhlola kanye nesimiso: · I-HRC Hardness Test isebenzisa i-DEAD CONE indenter ukucindezela endaweni ebonakalayo ngaphansi komthwalo we-150 kg, futhi inani lezinkambiso linqunywa ngokulinganisa ukujula kwe-induction. Izinhlobo ezisetshenziswayo ezisebenzayo: ③ Izimo zesicelo esijwayelekile: · Ukukhiqiza kanye nokulawulwa kwekhwalithi yamathuluzi okusika nokubumba. Ukuhlolwa kobunzima kwensimbi elukhuni. · Ukuhlola amagiya, ama-bearings kanye nezinye izingxenye ezinzima ezinobunzima obuphakeme. Izici nezinzuzo: Ukulinganiswa okusheshayo: Imiphumela yokuhlola ingatholwa ngesikhathi esifushane, esilungele ukuhlolwa okusheshayo emugqeni wokukhiqiza. · Isicelo Suede: Kuyasebenza ekuhlolweni kwezinhlobonhlobo zezinto eziphakeme kakhulu, ikakhulukazi insimbi ephethwe ukushisa kanye nensimbi yethuluzi. Amanothi noma ukulinganiselwa: Ukulinganiselwa Kwezinto Ezibonakalayo: Akulungele izinto ezithambile kakhulu, njengoba isigaxa sedayimane singacindezela ngaphezulu kwisampula, okuholela emiphumeleni yokulinganisa engalungile. Ukulungiswa Kwemishini: Imishini yokuhlola idinga ukulinganisa okujwayelekile nokulungiswa ukuze kuqinisekiswe ukunemba nokuqina kwesilinganiso.
(4) HRD
Indlela yokuhlola kanye nesimiso sokuhlolwa: Izinhlobo ezisetshenziswayo ezisebenzayo: ③ Izimo zesicelo esijwayelekile: · Ukulawulwa kwekhwalithi kanye nokuhlolwa kobulukhuni kwensimbi. Ukuhlolwa kobunzima bokuphakathi kokuqina okuphezulu. · Ithuluzi nokuhlola isikhunta, ikakhulukazi ngezinto zokwakha ezihambisana nobubanzi bukhuni obuphezulu. Izici nezinzuzo: · Ukulayisha okulinganiselwe Ukuphindaphinda okukhulu: I-Diamond Cone Indenter ihlinzeka ngemiphumela yokuhlolwa ethandekayo futhi ephindaphindekeke kakhulu. · Isicelo esiguqukayo: Kusebenza ekuhlolweni kobulukhuni bezinto ezahlukahlukene zezinto zokwakha, ikakhulukazi lezo phakathi kwebanga le-HRA neHRC. Amanothi noma ukulinganiselwa: Ukulinganiselwa kwezinto ezibonakalayo: ngezinto zokwakha ezinzima kakhulu noma ezithambile, i-HRD kungenzeka ingabi yisinqumo esifanele kunazo zonke. Ukulondolozwa Kwemishini: Imishini yokuhlola idinga ukulinganisa okujwayelekile nokulungiswa ukuze kuqinisekiswe ukunemba nokuthembela.
