Mekhoa ea tlhahlobo ea boima ba Rockwell Knoop le Vickers bakeng sa lirafshoa tsa aluminium nitride le mekhoa ea tlhahlobo ea li-bearings tsa tšepe.

1.Rockwell Knoop Vickers mokhoa oa ho lekola boima ba lirafshoa tsa aluminium nitride
Kaha lisebelisoa tsa ceramic li na le mohaho o rarahaneng, li thata ebile li brittle ka tlhaho, 'me li na le deformation e nyenyane ea polasetiki, mekhoa e tloaelehileng e sebelisoang ho bua ka thata e kenyelletsa Vickers hardness, Knoop hardness le Rockwell hardness. Khampani ea Shancai e na le mefuta e mengata e fapaneng ea liteko tsa thatafalo, tse nang le liteko tse fapaneng tsa ho thatafala le liteko tse fapaneng tse amanang le bothata.
Litekanyetso tse latelang li ka sebelisoa e le litšupiso:
GB/T 230.2 Metallic Materials Teko ea Matla a Rockwell:
Ho na le likala tse ngata tsa ho thatafala tsa Rockwell, 'me lisebelisoa tsa ceramic hangata li sebelisa sekala sa HRA kapa HRC.
GB/T 4340.1-1999 Metal Vickers teko ea boima le GB/T 18449.1-2001 Metal Knoop teko ea boima.
Mekhoa ea ho lekanya ea Knoop le Micro-Vickers ha e le hantle e tšoana, phapang ke li-indenters tse fapaneng tse sebelisoang.
Ke habohlokoa ho hlokomela hore ka lebaka la tlhaho e khethehileng ea sehlahisoa, re ka tlosa li-indent tsa Vickers tse sa nepahaleng ho ea ka boemo ba indentation nakong ea tekanyo ho fumana lintlha tse nepahetseng haholoanyane.
Mekhoa ea 2.Tlhahlobo ea li-bearings tsa tšepe
Ho latela mekhoa ea liteko tsa ho thatafala bakeng sa likarolo tsa tšepe le tšepe tse senang ferrous tse boletsoeng ho JB/T7361-2007, ho na le mekhoa e mengata ea liteko ho latela ts'ebetso ea workpiece, eo kaofela e ka lekoa ka tester ea thata ea Shancai:
1) Mokhoa oa ho lekola boima ba Vickers
Ka kakaretso, likarolo tse thata tsa sefahleho li lekoa ka mokhoa oa tlhahlobo ea boima ba Vickers. Tlhokomelo e lokela ho lefshoa ho fihlela qetellong ea workpiece le khetho ea matla a teko.
2) Mokhoa oa ho hlahloba boima ba Rockwell
Liteko tse ngata tsa ho thatafala ha Rockwell li etsoa ho sebelisoa sekala sa HRC. Shancai Rockwell hardness tester o bokelletse lilemo tse 15 tsa boiphihlelo mme ha e le hantle a ka fihlela litlhoko tsohle.
3) Mokhoa oa ho lekola boima ba Leeb
Teko ea boima ba Leeb e ka sebelisoa bakeng sa li-bearings tse kentsoeng kapa tse thata ho qhaqha. Ho nepahala ha tekanyo ea eona ha ho hantle joaloka teko ea boima ba benchtop.
Tekanyetso ena e sebetsa haholo-holo tekong ea boima ba likarolo tse nang le tšepe, likarolo tse nang le li-annealed le tse halefileng le likarolo tse feliloeng tsa ho jara hammoho le likarolo tsa tšepe tse se nang ferrous.
