I-Brinell hardness (HB) enobubanzi obuthile beebhola zentsimbi okanye iibhola ze-tungsten carbide, zicinezelwe kumphezulu wepateni yamandla ovavanyo aqingqwe kwangaphambili (F), emva kwexesha elimiselweyo lokubamba emva kwamandla ovavanyo lokuwisa, ububanzi bomlinganiselo wesampulu yokuhlohlwa komphezulu. (L).Amandla okuvavanya ubulukhuni beBrinell ahlulahlulwe nge-indentation spherical surface area quotient.Ukuya kwi-HBS (iBhola yeBhola yeBhola) iyunithi N/mm2 (MPa).Ifomula yile: apho: F - icinezelwe kumphezulu wesinyithi wesampulu yovavanyo lwamandla, N;D - uvavanyo lwebhola yentsimbi ububanzi, mm;d – i-avareji yomyinge wedayamitha mm.Ubulukhuni beBrinell bulinganiswe ngokuchaneka ngakumbi kwaye buthembekile, kodwa ngokubanzi i-HBS isebenza kuphela i-450N/mm2 (MPa) okanye ngaphantsi kwemathiriyeli yentsimbi, kwintsimbi eqinile, okanye ishiti elibhityileyo le-NA.Imigangatho Steel, Brinell ubulukhuni yeyona isetyenziswa kakhulu, kwaye kaninzi wathi ukuqina imathiriyeli, Idayamitha indentation d zombini enembile kwaye elula.

Ubulukhuni beBrinell yeyona ndlela isetyenziswa kakhulu ekuvavanyeni ubulukhuni bemibhobho yentsimbi yecarbon,.Le ndlela isebenzisa kwasekuqaleni, ngenxa yoshicilelo, kwaye ke ngoko ubulukhuni amaxabiso achatshazelwe yisampula umbutho microsegregation izithako ukungalingani impembelelo encinci, iziphumo zovavanyo ukufefa idigri encinci, reproducibility elungileyo, inokubonakalisa ngokungenanjongo ubulukhuni benjongo yezinto.

Umgaqo: Kumandla okufumanisa kwangaphambili, i-diameter ethile yebhola yentsimbi icinezelwe kwi-specimen surface ukugcina ixesha elithile, kwaye emva koko isuse amandla abhaqiweyo, umlinganiselo woxinzelelo lwe-diameter yoxinzelelo kumphezulu we-specimen, ingabalwa ngokusekelwe Idayamitha yoxinzelelo loshicilelo loxinzelelo luphawula indawo yegravure.Amandla okuvavanya ubulukhuni beBrinell ahlulahlulwe nge-indentation spherical surface area quotient.Iyunithi 9.807N/mm.Ibhola yentsimbi enkulu ecinezelwe kubunzulu, ubulukhuni obuphantsi;ngokuchaseneyo nobulukhuni amaxabiso ukuzibandakanya.
