The most widely used in production is the hardness of press-in method, such as Brinell hardness, Rockwell hardness, Vickers hardness and micro hardness. Boithuto bo fumanehang habonolo bo emela khatiso ea bokaholimo ba tšepe ho semolao sa polasetiki se bakoang ke lintho tse ling.
Tse latelang ke kenyelletso e khuts'oane ea likarolo tse fapaneng tsa thata:
1. Brinell Hardness (HB)
Tobetsa beithara ea tšepe e boima ea boholo bo itseng (hangata 10mm ka bophara Kamora hore mojaro o tlosoe, karolelano ea mojaro ho sebaka sa boikhathollo ke boleng ba boteng ba borikhoe ba brine
2. RockSwell Hardness (hr)
Ha HB> 450 kapa sampole e nyane haholo, teko ea boima ba brinell e ke ke ea sebelisoa le ho lekanya le boima ba mackwell Harnees. E sebelisa cone ea daemane ka vertex alelele le bolo ea tšepe e nang le bophara ba 1.59mm le 3.18mm ho tobetsa tlasa mojaro o itseng, 'me ho thata ho fumana thepa e itseng,' me ho thata ho fumana thepa e itseng. Ho latela ho thatafalloa ha thepa ea teko, e ka hlahisoa ka sekala se fapaneng le se fapaneng:
HRA: Ke thata ka ho sebelisa mojaro oa 60kg le Vemond Cone Indonter, 'me e sebelisetsoa lisebelisoa tse nang le thata e phahameng haholo (joalo ka Carbide ea cementa haholo (joalo ka Carbide e kholo, jj.).
HRB: Ke boima bo fumanoang ka ho sebelisa mojaro oa 100kg le bolo ea tšepe e thata ka bophara ba 1.58mm. E sebelisetsoa lisebelisoa tse nang le thata ka thata (tse kang tšepe e sa lefelloeng (joalo ka tšepe, joalo-joalo, tšepe, joalo-joalo).
HRC: Ke thata ka ho sebelisa mojaro oa 150kg le Vemond Cone Indeter, 'me e sebelisetsoa lisebelisoa tse nang le thata e phahameng (joalo ka tšepe e thata (e kang tšepe e thata, jj.).
3 Hards Hardness (HV)
Sebelisa lisekoere tse sekwere tsa diamond se nang le mojaro oa metsi a ka tlase ho 120kg
Ha ho bapisoa le liteko tsa boima ba Brinell le Rockwell Teko ea mathata a Vickirs, tlhahlobo ea Harkers e na le menyetla e mengata. Ha e na mathata a maemo a boletsoeng a ho beoa PAMETER D Joaloka Brinell, le Bothata ba Deformar ea Sengoloa; Ebile ha e na bothata ba hore boleng ba thata ba makhomo bo ke ke ba kopanya. 'Me e ka lekola thepa e bonolo e nang le majoe,' me e ka leka mathata a likarolo tse tšesaane haholo (kapa lipakaneng tse tšesaane) ho feta ka thata. Empa le tlas'a maemo a joalo, e ka bapisoa feela ka tekanyo e kholo ea majoe, 'me e ke ke ea emoloa ka maemo a mang a thata. Ntle le moo, ka lebaka leo Rockwell o sebelisa botebo ba leholimo le boemo ba boikhathollo bo lula bo le nyane ho feta bophara ba inducent, kahoo phoso ea eona e tla boela e kholo le ho feta. Ka hona, lintlha tsa likhakanyo tsa majoe ha li tsitsitse joalo ka li-brinell le tse hlabang, 'me ho sa tsilatsile,' me ho se tsitse le ho ikoetlisa.
Ho na le kamano e itseng ea phetoho pakeng tsa Brinell, Rockwell le Vickes, 'me ho na le tafole ea kamano e neng e tla khutlisoa.
