Ma muli o ka ho'āʻo paʻakikī a me ka microhardness Vickers, ua like ka huina daimana o ka indenter i hoʻohana ʻia no ke ana ʻana. Pehea e koho ai nā mea kūʻai aku i ka mea hōʻike paʻakikī Vickers? I kēia lā, e wehewehe pōkole wau i ka ʻokoʻa ma waena o ka mea hōʻike paʻakikī Vickers a me ka mea hōʻike microhardness.
ʻO ka hoʻāʻo ʻana i ka nui o ka ikaika ʻo Vickers paʻakikī a me ka microhardness tester scale
ʻO ka mea hoʻāʻo paʻakikī Vickers: ikaika hoʻāʻo F≥49.03N a i ʻole≥HV5
ʻO ka ukana liʻiliʻi ʻo Vickers paʻakikī: ikaika hoʻāʻo 1.961N≤F < 49.03N a i ʻole HV0.2 ~ < HV5
Mea hōʻike Microhardness: hoʻāʻo ikaika 0.09807N≤F <1.96N a i ʻole HV0.01 ~ HV0.2
No laila pehea mākou e koho ai i ka ikaika hoʻāʻo kūpono?
Pono mākou e hahai i ke kumu o ka nui o ka indentation, ʻoi aku ka pololei o ke ana ʻana inā ʻae nā kūlana workpiece, a koho e like me ka mea e pono ai, no ka mea, ʻoi aku ka liʻiliʻi o ka indentation, ʻoi aku ka nui o ka hewa i ke ana ʻana i ka lōʻihi diagonal, e alakaʻi i ka hoʻonui i ka hewa o ka waiwai paʻakikī.
ʻO ka ikaika hoʻāʻo o ka mea hōʻike microhardness ua lako maʻamau me: 0.098N (10gf), 0.245N (25gf), 0.49N (50gf), 0.98N (100gf), 1.96N (200gf), 2.94 (300gf), 4.90N, 4.90N (1000gf) (19.6N (2.0Kgf) koho)
Hoʻolako pinepine ʻia ka hoʻonui ʻia me: 100 mau manawa (nānā), 400 mau manawa (ana)
Hiki ke hoʻokaʻawale i ka pae ikaika o ka Vickers hardness tester: 2.94N (0.3Kgf), 4.9N (0.5Kgf), 9.8N (1.0Kgf), 19.6N (2.0Kgf), 29.4N (3.0Kgf), 49.0N (5.0Kgf), 49.0N (5.0Kgf), 49.0N (5.0Kgf), 49.0N (5.0Kgf), 196N (20Kgf), 294N (30Kgf), 490N (50Kgf) (ʻokoʻa nā ʻano hoʻohālike like ʻole.
ʻO ka hoʻonohonoho hoʻonui maʻamau: 100 manawa, 200 manawa
Hiki i ka Vickers hardness tester o Shandong Shancai/Laizhou Laihua Testing Instrument ke hana i nā ho'āʻo paʻakikī ma nā ʻāpana welded a i ʻole nā wahi wili.
E like me ke ana paakiki waiwai, ka maikai o ka weld a me ka metallurgical loli hiki ke hookolokolo. No ka laʻana, ʻo ka paʻakikī kiʻekiʻe paha ma muli o ke komo ʻana o ka wela i ka wā wili, ʻoiai ʻo ka haʻahaʻa haʻahaʻa hiki ke hōʻike i ka lawa ʻole o ka wiliwili a i ʻole nā pilikia o ka maikaʻi.
ʻO ka ʻōnaehana ana Vickers i hoʻonohonoho ʻia e holo i kahi papahana hoʻāʻo piha piha a hōʻike a hoʻopaʻa i nā hopena pili.
No nā hopena o ka hoʻāʻo ana, hiki ke hana ʻakomi ʻia ka hōʻike kiʻi pili.
He mea nui e hoʻomaopopo i ke koho ʻana i kahi wahi ʻelele oʻka weld e like me ka hoʻāʻo ʻana, e hōʻoia i kēia wahi ʻaʻohe pores, māwae a me nā hemahema ʻē aʻe e pili ana i nā hopena hōʻike.
Inā he mau nīnau kāu e pili ana i ka weld inspection, e ʻoluʻolu e kelepona mai iā mākou
