Origin of Vickers hardness tester
ʻO ka paʻakikī Vickers kahi maʻamau no ka hōʻike ʻana i ka paʻakikī mea i manaʻo ʻia e Robert L. Smith lāua ʻo George E. Sandland i ka makahiki 1921 ma Vickers Ltd. ʻO kēia kekahi ʻano hoʻāʻo paʻakikī ma hope o nā ʻano hoʻāʻo paʻakikī ʻo Rockwell a me Brinell.
ʻO ke kumu o Vickers hardness tester:
Hoʻohana ka Vickers hardness tester i ka ukana o 49.03~980.7N e kaomi i kahi daimana conical square me kahi kihi pili o 136 ° i ka ʻili o ka mea.Ma hope o ka paʻa ʻana no ka manawa i ʻōlelo ʻia, helu ʻia ka waiwai paʻakikī o Vickers ma ke ana ʻana i ka lōʻihi diagonal o ka indentation a me ka hoʻohana ʻana i ke ʻano.
ʻO ka laulā noi hoʻouka o nā ʻano ʻekolu o Vickers (micro Vickers):
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.
Haʻahaʻa haʻahaʻa Vickers paakiki, ho'āʻo ukana <1.949.03N, kūpono no ka paakiki ana o thinner workpieces, mea paahana surfaces, a me ka uhi;
ʻO Micro Vickers paʻakikī, hoʻāʻo haʻahaʻa<1.961N, kūpono no ke ana ʻana i ka paʻakikī o nā ʻāpana metala a me nā papa ʻili lahilahi.
Eia hou, ua lako me ka Knoop indenter, hiki iā ia ke ana i ka paʻakikī Knoop o nā mea palupalu a me nā mea paʻakikī e like me ke aniani, ka ceramics, agate, a me nā pōhaku kiʻi.
ʻO nā mea maikaʻi o Vickers hardness tester:
1. He akea ka laulā ana, mai nā metala lako polokalamu a hiki i nā metala superhard, a hiki ke ʻike ʻia, mai kahi liʻiliʻi a ʻekolu tausani Vickers paʻakikī waiwai.
2. He liʻiliʻi ka indentation aʻaʻole e hōʻino i ka mea hana, hiki ke hoʻohanaʻia no ka ho'āʻo paʻakikī i nā mea hana i hikiʻole ke hōʻinoʻia ma kaʻili o ka mea hana.
3. Ma muli o kona ikaika ho'āʻo liʻiliʻi, hiki i ka ikaika hoʻāʻo liʻiliʻi ke hiki i 10g, hiki ke ʻike i kekahi mau mea hana lahilahi a liʻiliʻi.
ʻO nā hemahema o Vickers hardness tester:
Ke hoʻohālikelike ʻia me nā ʻano hoʻāʻo paʻakikī ʻo Brinell a me Rockwell, loaʻa i ka Vickers hardness test nā koi no ka maʻalahi o ka ʻili o ka mea hana.Pono kekahi mau mea hana i ka polishing, ʻo ia ka manawa e hoʻopau ai a paʻa i ka hana
ʻO nā mea hōʻike paʻakikī ʻo Vickers he ʻano pololei a ʻaʻole kūpono no ka hoʻohana ʻana i nā hale hana a i ʻole ma ka pūnaewele, a hoʻohana nui ʻia i loko o nā laboratories.
ʻO Shandong Shancai Vickers moʻo hōʻike paʻakikī (kiʻi no Wang Songxin)
1. Economic Vickers mea ho'āʻo paʻakikī
2. Hōʻike kikohoʻe a me ka pā paʻi paʻakikī Vickers hōʻike
3. Ho'āʻo paʻakikī Vickers piha piha
