ʻO ka ʻōnaehana hoʻāʻo paʻakikī Vickers

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 ma 1921 ma Vickers Ltd. ʻO kēia kekahi ʻano hana 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 pōmaikaʻi 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 hoʻāʻo 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. Mea ho'āʻo paʻakikī Vickers piha piha
