Brinell hardness scale

Teko ea ho thatafala ha Brinell e entsoe ke moenjiniere oa Sweden Johan August Brinell ka 1900 'me e ile ea sebelisoa pele ho lekanya ho thatafala ha tšepe.
(1)HB10/3000
① Mokhoa oa teko le molao-motheo: bolo ea tšepe e bophara ba 10 mm e hatelloa ka holim'a thepa ka tlas'a mojaro oa 3000 kg, 'me bophara ba indentation bo lekanyetsoa ho bala boleng ba boima.
② Mefuta ea lisebelisoa tse sebetsang: E ​​loketse lisebelisoa tsa tšepe tse thata tse kang tšepe e entsoeng ka tšepe, tšepe e thata, li-alloys tse boima, joalo-joalo.
③Maemo a tloaelehileng a ts'ebeliso: Teko ea lisebelisoa tsa mochini o boima le lisebelisoa. Teko ea boima ba li-castings tse kholo le forgings. Taolo ea boleng boenjiniere le tlhahiso.
④Likarolo le melemo: Mojaro o moholo: E loketse lisebelisoa tse teteaneng le tse thata, e khona ho mamella khatello e kholo, le ho netefatsa liphetho tse nepahetseng tsa tekanyo. Durability: Indenter ea bolo ea tšepe e na le nako e telele ea nako e telele 'me e loketse tšebeliso ea nako e telele le e pheta-phetoang. Mefuta e mengata ea lisebelisoa: E khona ho leka mefuta e fapaneng ea lisebelisoa tsa tšepe tse thata.
⑤ Lintlha kapa mefokolo: Boholo ba mohlala: Ho hlokahala sampole e kholoanyane ho etsa bonnete ba hore indentation e kholo ka ho lekana ebile e nepahetse, 'me bokaholimo ba sampuli bo tlameha ho ba sephara le ho hloeka. Litlhoko tsa bokaholimo: Bokaholimo bo hloka ho ba boreleli le ho hloka litšila ho netefatsa ho nepahala ha tekanyo. Tlhokomelo ea lisebelisoa: Thepa e hloka ho lekanyetsoa le ho hlokomeloa khafetsa ho netefatsa ho nepahala le ho pheta-pheta ha tlhahlobo.
(2)HB5/750
① Mokhoa oa teko le molao-motheo: Sebelisa bolo ea tšepe e bophara ba limilimithara tse 5 ho hatella holim'a thepa ka tlas'a mojaro oa 750 kg, 'me u lekanye bophara ba ho indentation ho bala boleng ba boima.
② Mefuta ea lisebelisoa tse sebetsang: E ​​sebetsa ho thepa ea tšepe e nang le boima bo mahareng, joalo ka lialloys tsa koporo, lialloys tsa aluminium, le tšepe e thata e mahareng. ③ Maemo a tloaelehileng a ts'ebeliso: Taolo ea boleng ba lisebelisoa tsa tšepe tse thata. Patlisiso ea lintho tse bonahalang le nts'etsopele le liteko tsa laboratori. Teko ea boima ba thepa nakong ea tlhahiso le ts'ebetso. ④ Likarolo le melemo: Mojaro o mahareng: E ​​sebetsa ho thepa e thata e mahareng mme e khona ho lekanya ho tiea ha tsona ka nepo. Sesebelisoa se feto-fetohang: E ​​sebetsa ho mefuta e fapaneng ea boima ba mahareng e nang le maemo a matla. Ho pheta-pheta ho phahameng: E ​​fana ka liphetho tse tsitsitseng le tse tsitsitseng tsa tekanyo.
⑥ Lintlha kapa mefokolo: Tokiso ea sampole: Sebaka sa sampole se hloka ho ba sephara le ho hloeka ho netefatsa bonnete ba liphetho tsa tekanyo. Meeli ea lintho tse bonahalang: Bakeng sa lisebelisoa tse bonolo haholo kapa tse thata haholo, ho ka hlokahala hore ho khethoe mekhoa e meng e loketseng ea teko ea boima. Tlhokomelo ea lisebelisoa: Thepa e hloka ho lekanngoa le ho hlokomeloa khafetsa ho netefatsa ho nepahala le ho tšepahala ha tekanyo.
(3)HB2.5/187.5
① Mokhoa oa teko le molao-motheo: Sebelisa bolo ea tšepe e bophara ba 2.5 mm ho hatella holim'a thepa ka tlas'a mojaro oa 187.5 kg, 'me u lekanye bophara ba ho indentation ho bala boleng ba boima.
② Mefuta ea lisebelisoa tse sebetsang: E ​​sebetsa ho lisebelisoa tsa tšepe tse bonolo le lisebelisoa tse ling tse bonolo, joalo ka aluminium, alloy lead le tšepe e bonolo.
③Maemo a tloaelehileng a ts'ebeliso: Taolo ea boleng ba lisebelisoa tsa tšepe tse bonolo. Teko ea lisebelisoa liindastering tsa elektroniki le tsa motlakase. Teko ea boima ba lisebelisoa tse bonolo nakong ea tlhahiso le ho sebetsa.
④Likarolo le melemo: Mojaro o tlase: E sebetsa ho lisebelisoa tse bonolo ho qoba ho indentation haholo. Ho pheta-pheta ho phahameng: E ​​fana ka liphetho tse tsitsitseng le tse tsitsitseng tsa tekanyo. Mefuta e mengata ea lisebelisoa: E khona ho leka mefuta e fapaneng ea lisebelisoa tsa tšepe tse bonolo.
⑤ Lintlha kapa meeli: Tokiso ea mohlala: Sebaka sa mohlala se hloka ho ba se bataletseng le se hloekileng ho netefatsa ho nepahala ha liphetho tsa tekanyo. Meeli ea lintho tse bonahalang: Bakeng sa thepa e thata haholo, ho ka hlokahala ho khetha mekhoa e meng e loketseng ea teko ea boima. Tlhokomelo ea lisebelisoa: Thepa e hloka ho lekanyetsoa le ho hlokomeloa khafetsa ho netefatsa hore litekanyo li nepahetse le ho tšepahala.
