ʻO ka nui pinepine i ka hana 'ana ka paʻakikī o ka paʻiʻana, e like me ka paʻakikī paʻakikī, nā paʻakikī paʻakikī. ʻO ka waiwai paʻakikī i loaʻa i keʻano o ka paleʻana o kaʻaoʻao o ka mea hao i ka engsication plasticeation i hoʻokumuʻia e ka mea'ē aʻe.
ʻO kēia kahi mea pōkole i kēia manawa i nā'āpana paʻakikī likeʻole:
1.
E kaomi i kahi pōkō paʻakikī paʻakikī o kekahi nui (maʻamau 10mm i ka disturter) Ma hope o ka laweʻiaʻana o ka ukana,ʻo ka pae o ka ukana i ka'āina paʻakikīʻo ia ka waiwai paʻakikī o Burnell (HB).
2.ʻO ka paʻakikī o Rockwell paʻakikī (HR)
I ka wa e hb> Hoʻohana ia i kahi cone daimana me kahi kihi vertex o 120 ° a iʻole kahi pahu kila ma lalo o ka hohonu o kahi mea i loaʻa mai E like me ka paʻakikī o ka mea hōʻike hōʻike, hiki ke hōʻikeʻia ma nā'āpanaʻekolu:
Hra:ʻo ia ka mea paʻakikī i loaʻa ma o ka hoʻohanaʻana i kahi ukana 60KG a me kahi mea i hoʻopaʻaʻia, a e like me nā mea iʻike nuiʻia (etc.).
HRB:ʻO ia ka mea paʻakikī i loaʻa ma o ka hoʻohanaʻana i kahi ukana 100kg a me kahi pōpō kila paʻakikī a me kahi'āpana paʻakikī o 1.58mm. Hoʻohanaʻia ia no nā mea me ka paʻakikī haʻahaʻa (e like me nā mea hao hao,ʻo ka hao hao, etc.).
HRC:ʻO ia ka mea paʻakikī i loaʻa ma o ka hoʻohanaʻana i kahi ukana 150kg a me kahi mea i hoʻopaʻaʻia, a e like me nā mea paʻakikī paʻakikī.
3 mau mea hoʻoikaika maikaʻi (HV)
E hoʻohana i kahi pahu pahu pahu pahu pahu pahu me ka ukana ma lalo o 120kg a me kahi'āpana o ka waiwai o ka waiwai
Hoʻohālikelikeʻia me Brinell a me Binywell paʻakikī paʻakikī, ua nui nā hōʻike paʻakikī o Vickers. ʻAʻole pono ia i nā palena o nā kūlana i hōʻikeʻiaʻo P a me Indenter DIAMETer D e like me Blirine, a me ka pilikia o ka hapaha o ka Indenter o Indenter. ʻAʻole hoʻi e loaʻa i ka pilikia e hiki ke hoʻohuiʻia ka waiwai paʻakikī o ka pōhaku. A hiki iā ia ke hōʻike i nā mea palupalu a me nā mea paʻakikī e like me ka pōhaku, a hiki iā ia ke ho'āʻo i ka paʻakikī o nā'āpana he nui. Aka, maloko o na mea la, hiki maloko o loko o loko o ka laula, e hiki auanei e hoowale mai e nā pae kiʻekiʻe kiʻekiʻe. Eia kekahi, no ka mea, ua hoʻohanaʻo Rockwell i ka hohonu hohonu e like me keʻano o ke anaʻana, a he nui loa ka hohonu No laila,ʻaʻole like ka nui o kaʻikepili paʻakikī e like me nā brarine a me nā vickers, a me keʻano e like me nā mea nui.
Aia kekahi pilina pili ma waena o Brinell, Rockwell a me Vickers, a aia kahi papa pili pili e pili ana i hiki ke nīnauʻia.
