ʻO ka paʻakikī Brinell maʻamau, ka paʻakikī Rockwell a me ka paʻakikī Vickers o nā mea metala no ka paʻakikī indentation. ʻO ka waiwai paʻakikī e hōʻike ana i ka hiki o ka ʻili o ke kino ke pale aku i ka hoʻololi ʻana o ka plastic i hana ʻia e kekahi mea i kaomi ʻia i loko; C) e ana i ka paʻakikī, a ʻo ka waiwai paʻakikī e hōʻike ana i ka nui o ka hana hoʻololi elastic o ka metala.
ʻO Brinell Hardness
E hoʻohana i ka pōpō kila kinai ʻia a i ʻole ka pōpō huila paʻa me ke anawaena o D ma ke ʻano he indenter, e kaomi i ka ʻili o ka ʻāpana hoʻāʻo me ka ikaika hoʻāʻo like F, a ma hope o ka manawa paʻa i ʻōlelo ʻia, e hoʻoneʻe i ka ikaika hoʻāʻo e loaʻa kahi indentation me he anawaena o d. E puunaue i ka ikaika hoao ma ka ili o ka indentation, a o ka waiwai i loaa mai ka waiwai paakiki Brinell, a ua hoikeia ka hoailona e HBS a i ole HBW.
ʻO ka ʻokoʻa ma waena o HBS a me HBW ka ʻokoʻa i ka indenter. HBS 'o ia ho'i ka indenter he pōpō kila pa'akiki, i ho'ohana 'ia no ke ana 'ana i nā mea me ka waiwai pa'akikī Brinell ma lalo o 450, e like me ke kila ha'aha'a, ka hao hina a me nā metala non-ferrous. HBW 'o ia ho'i, 'o ka indenter he carbide cemented, ka mea i ho'ohana 'ia no ke ana 'ana i nā mea me ka waiwai pa'akikī Brinell ma lalo o 650.
No ka poloka ho'āʻo hoʻokahi, inā like nā kūlana hoʻokolohua ʻē aʻe, ʻokoʻa nā hopena o nā hoʻokolohua ʻelua, a ʻoi aku ka nui o ka waiwai HBW ma mua o ka waiwai HBS, a ʻaʻohe kānāwai quantitative e hahai.
Ma hope o ka makahiki 2003, ua hoʻokō like koʻu ʻāina i nā kūlana o ka honua, ua kāpae i nā mea hoʻokomo pōpō kila, a me nā poʻo pōpō carbide i hoʻohana ʻia. No laila, ua hoʻopau ʻia ka HBS, a ua hoʻohana ʻia ʻo HBW e hōʻike i ka hōʻailona paʻakikī Brinell. I nā manawa he nui, hōʻike wale ʻia ka paʻakikī Brinell ma HB, e pili ana iā HBW. Eia naʻe, ʻike ʻia ka HBS i kēlā me kēia manawa ma nā pepa palapala.
He kūpono ke ʻano ana paʻakikī ʻo Brinell no ka hao hao, nā mea hao non-ferrous, nā kila annealed a me nā mea i hoʻopaʻa ʻia, a ʻaʻole kūpono no ka hoʻāʻo ʻana i nā laʻana a i ʻole.ʻāpana hoʻohuli cncʻo ia ka paʻakikī, liʻiliʻi loa, ʻeleʻele loa, a i ʻole ʻae ʻole i nā kaha nui ma ka ʻili.
ʻO Rockwell Hardness
E hoʻohana i ka cone daimana me ka huina cone o 120° a i ʻole Ø1.588mm a me Ø3.176mm i pio kila pōlele e like me ka indenter a me ka ukana e hui pū me ia. ʻO ka ukana mua he 10kgf a ʻo ka ukana holoʻokoʻa he 60, 100 a i ʻole 150kgf (ʻo ia hoʻi, ka ukana mua me ka ukana nui). Hōʻike ʻia ka paʻakikī e ka ʻokoʻa ma waena o ka hohonu indentation i ka wā e wehe ʻia ai ka ukana nui a me ka hohonu indentation i ka wā e paʻa ai ka ukana nui a me ka hohonu indentation ma lalo o ka ukana mua ma hope o ka hoʻohana ʻana i ka ukana holoʻokoʻa.
Hoʻohana ka hoʻāʻo paʻakikī ʻo Rockwell i ʻekolu mau kaha hoʻāʻo a me ʻekolu indenters. He 9 hui o ia mau mea, e like me na unahi 9 o ka paakiki o Rockwell. ʻO ka hoʻohana ʻana o kēia mau lula 9 e uhi i nā mea metala maʻamau. ʻEkolu ʻekolu HRA, HRB a me HRC, ma waena o ka HRC ka mea hoʻohana nui loa.
Hoʻohana mau ʻia ʻo Rockwell hardness test table specification:

ʻO ka laulā o ka hoʻohana ʻana i ka pālākiō HRC ʻo 20 ~ 70HRC. Ke emi ka waiwai paakiki ma mua o 20HRC, no ka mea, o ka conicalalumini cnc machining hapapaʻi nui ʻia ka indenter, emi ka naʻau, a pono e hoʻohana ʻia ka unahi HRB; ke ʻoi aku ka paʻakikī o ka hāpana ma mua o 67HRC, ʻoi aku ka nui o ke kaomi ʻana ma ka piko o ka indenter, a ua maʻalahi ka pōʻino o ke daimana. E hoʻopōkole loa ʻia ke ola o ka indenter, no laila e hoʻohana maʻamau ka pālākiō HRA.
He mea maʻalahi, wikiwiki, a liʻiliʻi ka hoʻāʻo ʻana o ka paʻakikī ʻo Rockwell, a hiki ke hoʻāʻo i ka ʻili o nā huahana i hoʻopau ʻia a me nā mea hana paʻa a lahilahi. Ma muli o ka liʻiliʻi indentation, no nā mea me ka uneven hale a me ka paakiki, ka paakiki waiwai fluctuates nui, a me ka pololei, aole e like me ka Brinell paakiki. Hoʻohana ʻia ka paʻakikī ʻo Rockwell e hoʻoholo ai i ka paʻakikī o ke kila, nā metala non-ferrous, nā ʻāpana paʻakikī, etc.
Vickers Hardness Vickers Hardness
Ua like ke kumu o ke ana paakiki o Vickers me ko Brinell paakiki. E hoʻohana i ka indenter pyramid square diamond me kahi kihi i hoʻokomo ʻia o 136° e kaomi i ka ʻili o ka mea me ka ikaika hoʻāʻo F, a wehe i ka ikaika hoʻāʻo ma hope o ka mālama ʻana i ka manawa i ʻōlelo ʻia. Hōʻike ʻia ka paʻakikī e ka ʻawelike kaomi ma ka ʻāpana ili o ka indent pyramid square. ʻO ka waiwai, ʻo ka hōʻailona hōʻailona he HV.
He nui ke ana paakiki o Vickers, a hiki ke ana i na mea me ka paakiki mai 10 a 1000HV. He liʻiliʻi ka indentation, a hoʻohana maʻamau ia e ana i nā mea ʻoi aku ka lahilahi a me nā papa paʻakikī i luna e like me ka carburizing a me ka nitriding.
Leeb Paʻakikī Leeb Paʻakikī
E hoʻohana i kahi kino hopena me kahi poʻo pōpō tungsten carbide e hoʻopā i ka ʻili o ka ʻāpana hoʻāʻo ma lalo o ka hana a kekahi ikaika, a laila hoʻihoʻi hou. Ma muli o ka ʻokoʻa o ka paʻakikī o nā mea, ʻokoʻa ka wikiwiki o ka rebound ma hope o ka hopena. Hoʻokomo ʻia kahi magnet paʻa ma ka ʻaoʻao hopena. Ke neʻe ke kino hopena i luna a i lalo, e hoʻoulu ʻia kona ʻōwili peripheral i kahi hōʻailona electromagnetic e like me ka wikiwiki, a laila hoʻololi iā ia i waiwai paʻakikī Leeb ma o kahi kaapuni uila. Hōʻailona ʻia ka hōʻailona e like me HL.
ʻAʻole pono ka Leeb hardness tester i kahi papa hana, a ʻo kāna mea ʻike paʻakikī e like me ka peni, hiki ke hana pololei ʻia e ka lima, a hiki ke ʻike maʻalahi inā he mea hana nui, kaumaha a i ʻole kahi mea hana me nā ana geometric paʻakikī.
ʻO kekahi pōmaikaʻi ʻē aʻe o Leeb paʻakikī ʻo ia ka liʻiliʻi o ka pōʻino i ka ʻili o ka huahana, a i kekahi manawa hiki ke hoʻohana ʻia e like me ka hoʻāʻo ʻole luku; ʻokoʻa ia i nā hoʻāʻo paʻakikī ma nā ʻaoʻao āpau, nā ākea ākea a kūikawāʻāpana alumini.
Hoʻopili ʻo Anebon i ka ʻōlelo ʻo "Honest, hoʻoikaika, hoʻoikaika, hana hou" e loaʻa mau i nā hopena hou. Manaʻo ʻo Anebon i nā manaʻo, ʻo ka kūleʻa e like me kāna kūleʻa pilikino.
