I-Brinell hardness (HB) enobubanzi obuthile bamabhola ensimbi noma amabhola e-tungsten carbide, icindezelwe endaweni yephethini yamandla okuhlola anqunywe kusengaphambili (F), ngemva kwesikhathi esinqunyiwe sokubamba esinqunywe kusengaphambili ngemva kwamandla okuhlola ukuwa, ububanzi bokulinganisa kwendawo yokuhlehlisa isampula. (L).Amandla okuhlola ubulukhuni be-Brinell ahlukaniswe nge-quotient yendawo eyindilinga ye-indentation.Ku-HBS (Ibhola Lebhola Lebhola) iyunithi N/mm2 (MPa).Ifomula ithi: lapho: F – icindezelwe endaweni yensimbi yesampula yamandla okuhlola, N;D - ukuhlola ububanzi bebhola lensimbi, mm;d – i-indentation average diameter mm.Ukuqina kwe-Brinell kukalwa kunembile futhi kuthembekile, kodwa ngokuvamile i-HBS isebenza kuphela ku-450N/mm2 (MPa) noma ngaphansi kwempahla yensimbi, kunsimbi eqinile, noma ishidi elincane elingu-NA.Izindinganiso zensimbi, ubulukhuni be-Brinell busetshenziswa kakhulu, futhi ngokuvamile kuthiwa ubulukhuni bezinto ezibonakalayo, ububanzi bokuhlehlisa d kokubili enembile futhi elula.

Ubulukhuni be-Brinell buyindlela esetshenziswa kakhulu ekuhloleni ubulukhuni bepayipi lensimbi, .Le ndlela isebenzisa yasekuqaleni, ngenxa imprint yayo, futhi kanjalo ubulukhuni amagugu ethintwe isampula inhlangano microsegregation izithako ukungalingani ubuncane umthelela, imiphumela yokuhlola afafaze degree encane, reproducibility omuhle, kungabonisa ngobuqotho ubulukhuni inhloso indaba.

Isimiso: Kumandla okuthola anqunywe kusengaphambili, ububanzi obuthile bebhola lensimbi sicindezelwa endaweni yesifanekiso ukuze kugcinwe isikhathi esithile, bese kususwa amandla atholiwe, ukulinganisa kobubanzi bokucindezela okugxilile endaweni yesampula, kungabalwa ngokusekelwe ububanzi bengcindezi ye-pressure imprint bubonisa indawo ye-gravure.Amandla okuhlola ubulukhuni be-Brinell ahlukaniswe nge-quotient yendawo eyindilinga ye-indentation.Iyunithi 9.807N/mm.I-indentation Ibhola lensimbi elikhulu elicindezelwe ekujuleni, amanani obulukhuni obuphansi;okuphambene nalokho ubulukhuni amagugu ukuzibandakanya.
