Te pūtake o te whakamātautau pakeke a Vickers
Ko te pakeke o Vickers he paerewa mō te whakaatu i te pakeke o ngā rauemi i whakatakotoria e Robert L. Smith rāua ko George E. Sandland i te tau 1921 i Vickers Ltd. Ko tētahi atu tikanga whakamātautau pakeke tēnei e whai ana i ngā tikanga whakamātautau pakeke o Rockwell me Brinell.
Te mātāpono o te whakamātautau pakeke Vickers:
Ka whakamahia e te whakamātautau pakeke Vickers he kawenga o te 49.03~980.7N hei pēhi i tētahi taimana tapawhā kōniko me te koki whanaunga o te 136° ki roto i te mata o te rauemi. I muri i te pupuri mō te wā kua tohua, ka tatauhia te uara pakeke Vickers mā te ine i te roa whakarara o te kōhao me te whakamahi i te tātai.
Ko te whānuitanga o te kawenga o ngā momo Vickers e toru e whai ake nei (micro Vickers):
He pai te taputapu whakamātautau pakeke Vickers me te kawenga 49.03~980.7N mō te ine i te pakeketanga o ngā wahi mahi nunui ake me ngā paparanga mata hohonu ake.
He iti te taumaha o te pakeke Vickers, he iti te taumaha whakamātautau mō te 1.949.03N, he pai mō te ine i te pakeke o ngā wahi mahi angiangi, ngā mata taputapu, ngā paninga rānei;
Te pakeke o Micro Vickers, te kawenga whakamātautau <1.961N, he pai mō te ine i te pakeke o ngā pepa whakarewa me ngā paparanga mata tino angiangi.
Hei tāpiritanga, he mea whakauru ki te kōhao Knoop, ka taea e ia te ine i te pakeke o Knoop o ngā rauemi pakarukaru me ngā rauemi mārō pērā i te karāhe, te uku, te ākete me ngā kohatu horihori.
Ngā painga o te taputapu whakamātautau pakeke Vickers:
1. He whānui te whānuitanga ine, mai i ngā konganuku pūmanawa ki ngā konganuku tino mārō, ā, ka taea te kite, mai i te torutoru ki te toru mano ngā uara mārō Vickers.
2. He iti te kōhao, ā, kāore e kino te mea mahi, ka taea te whakamahi mō te whakamātautau pakeke i runga i ngā mea mahi kāore e taea te kino i runga i te mata o te mea mahi.
3. Nā te iti o te kaha whakamātautau, ka taea e te kaha whakamātautau iti rawa te tae ki te 10g, ka taea te kite i ētahi wahi mahi angiangi me te iti.
Ngā ngoikoretanga o te taputapu whakamātautau pakeke Vickers:
Ki te whakatauritea ki ngā tikanga whakamātautau pakeke a Brinell me Rockwell, he whakaritenga kei te whakamātautau pakeke a Vickers mō te maeneene o te mata o te mea mahi. Ko ētahi mea mahi me whakakanapa, he mea e pau ana te wā me te mahi nui.
He tino tika ngā taputapu whakamātautau pakeke a Vickers, ā, kāore e pai mō te whakamahi i roto i ngā awheawhe, i te papa rānei, ā, ko te nuinga o te wā e whakamahia ana i roto i ngā taiwhanga.
