Ka lebaka la tlhahlobo ea boima ba Vickers le microhardness, angle ea daemane ea indenter e sebelisetsoang ho metha e tšoana. Bareki ba lokela ho khetha Vickers hardness tester joang? Kajeno, ke tla hlalosa ka bokhutšoanyane phapang pakeng tsa Vickers hardness tester le microhardness tester.
Teko karohano ea boholo ba Vickers hardness le microhardness tester scale
Vickers hardness tester: matla a teko F≥49.03N kapa≥HV5
Boima bo bonyenyane ba Vickers: matla a teko 1.961N≤F <49.03N kapa HV0.2 ~ <HV5
Microhardness tester: matla a teko 0.09807N≤F <1.96N kapa HV0.01 ~ HV0.2
Joale re lokela ho khetha matla a loketseng a teko joang?
Re lokela ho latela molao-motheo oa hore ho indentation e kholoanyane, boleng ba tekanyo e nepahetseng haholoanyane haeba maemo a workpiece a lumella, 'me u khethe ha ho hlokahala, hobane ho fokotseha ho hoholo, ho na le phoso e kholo ea ho lekanya bolelele ba diagonal, e leng se tla lebisa ho eketseha ha phoso ea boleng ba boima.
Matla a tekolo a tester ea microhardness hangata e na le: 0.098N (10gf), 0.245N (25gf), 0.49N (50gf), 0.98N (100gf), 1.96N (200gf), 2.94 (300gf), 500gf), 9. (1000gf) (19.6N (2.0Kgf) ha u rata)
Kakaretso ea ho holisa e na le: makhetlo a 100 (ho shebella), makhetlo a 400 (tekanyo)
Boemo ba matla a teko ea Vickers hardness tester e ka aroloa ka: 2.94N (0.3Kgf), 4.9N (0.5Kgf), 9.8N (1.0Kgf), 19.6N (2.0Kgf), 29.4N (3.0Kgf), 49.0N (5.0Kg0), (10Kg0), (1. 196N (20Kgf), 294N (30Kgf), 490N (50Kgf) (mefuta e fapaneng e na le litlhophiso tse fapaneng tsa matla a teko.)
Tlhophiso ea ho holisa hangata ke: makhetlo a 100, makhetlo a 200
Vickers hardness tester ea Shandong Shancai/Laizhou Laihua Testing Instrument e ka etsa liteko tsa ho thatafala likarolong tse cheselitsoeng kapa libakeng tse chesellang.
Ho ea ka boleng bo lekantsoeng ba boima, boleng ba weld le liphetoho tsa metallurgical li ka ahloloa. Ka mohlala, boima bo phahameng haholo bo ka 'na ba bakoa ke ho kenya mocheso o feteletseng nakong ea ho cheselletsa, ha boima bo tlaase haholo bo ka bontša mathata a sa lekaneng kapa mathata a boleng ba thepa.
Sistimi e hlophisitsoeng ea ho lekanya Vickers e tla tsamaisa lenaneo la tlhahlobo le othomathike ka botlalo le ho bonts'a le ho tlaleha liphetho tse tsamaellanang.
Bakeng sa liphetho tsa tlhahlobo ea tekanyo, tlaleho e tsamaellanang ea litšoantšo e ka hlahisoa ka bo eona.
Ke habohlokoa ho hlokomela hore ha u khetha sebaka sa moemeli oa.the weld e le ntlha ea teko, etsa bonnete ba hore sebaka sena ha se na li-pores, mapetsong kapa likoli tse ling tse ka amang liphello tsa liteko.
Haeba u na le lipotso mabapi le tlhahlobo ea weld, ikutloe u lokolohile ho ikopanya le rona
