ʻO ka paʻakikī Vickers kahi maʻamau no ka hōʻike ʻana i ka paʻakikī o nā mea i manaʻo ʻia e British Robert L. Smith lāua ʻo George E. Sandland i ka makahiki 1921 ma Vickers Ltd. ʻO kēia kekahi ʻano hana hoʻāʻo paʻakikī ma hope o nā ʻano hoʻāʻo paʻakikī o Rockwell a me Brinell.
1 Kumu o Vickers mea ho'āʻo paʻakikī:
Hoʻohana ka Vickers hardness tester i ka ukana o 49.03 ~ 980.7N e kaomi i kahi mea hoʻoheheʻe daimana cone-like me kahi kihi o 136 ° ma ka ʻili.Ma hope o ka mālama ʻana iā ia no kahi manawa i ʻōlelo ʻia, e ana i ka indentation diagonal.Ka lōʻihi o ka laina, a laila e helu i ka waiwai paʻakikī o Vickers e like me ke kumu.
2. Hoʻouka i ka laulā noi:
01: ʻO ka mea hōʻike paʻakikī Vickers me ka ukana o 49.03~980.7N kūpono no ke ana paʻakikī o nā mea hana nui a me nā papa hohonu hohonu;
02: ʻO ka haʻahaʻa liʻiliʻi ʻo Vickers paʻakikī, hoʻāʻo haʻahaʻa <1.949.03N, kūpono no ke ana ʻana i ka paʻakikī o nā mea hana lahilahi, nā mea hana a i ʻole nā uhi;
03: Micro-Vickers paakiki, ho'āʻo haʻawe <1.961N, kūpono no ka paakiki ana o ka metala foils a me ka lahilahi o ka ili.
Eia hou, ua lako me ka Knoop indenter, hiki iā ia ke ana i ka paʻakikī Knoop o nā mea palupalu a paʻakikī e like me ke aniani, ka seramika, agate, a me nā pōhaku kiʻi.
3 Nā mea maikaʻi o Vickers hardness tester:
1) He laula ka laulā ana, mai nā metala palupalu a hiki i nā mea ho'āʻo ultra-paʻakikī a hiki i nā metala paʻakikī, a ʻo ke ana ʻana mai kahi liʻiliʻi a ʻekolu tausani Vickers koʻikoʻi paʻakikī.
2) He liʻiliʻi ka indentation a ʻaʻole e hōʻino i ka mea hana.Hiki ke hoʻohana ʻia no ka hoʻāʻo ʻana i ka paʻakikī o nā mea hana ʻaʻole hiki ke pohō ka ʻili.
3) Ma muli o kona ikaika ho'āʻo liʻiliʻi, hiki i ka ikaika hoʻāʻo liʻiliʻi ke hiki i 10g, no laila hiki iā ia ke ʻike i kekahi mau mea hana lahilahi a liʻiliʻi.
4 Nā hemahema o ka Vickers hardness tester: Ke hoʻohālikelike ʻia me Brinell a me Rockwell nā ʻano hoʻāʻo paʻakikī, ʻo ka Vickers hardness test nā koi no ka maʻalahi o ka ʻili o ka mea hana, a pono e poni ʻia kekahi mau mea hana, ʻo ia ka manawa a me ka hana;ka mālama ʻana ʻO ka mea hōʻike paʻakikī he pololei a ʻaʻole kūpono no ka hoʻohana ʻana i nā hale hana a i ʻole ma ka pūnaewele.Hoʻohana nui ʻia ia i nā laboratories.
5 Vickers mea ho'āʻo paʻakikī
1) Mea ho'āʻo paʻakikī Vickers waiwai
2) Hōʻike kikohoʻe hoʻopā pale Vickers paakiki mea ho'āʻo
3) Mea ho'āʻo paʻakikī Vickers piha piha
