Mai i te HRC ki te HV: Me pēhea te Tahuri me te Whakamāori i ngā Uara Mārō i roto i ngā Pereti Paparua Chromium Carbide

Ina tae ki te aromatawai i te mahi a tētahipereti kakahu whakakikorua chromium carbide, ko te pakeketanga tētahi o ngā tohu tino nui. Heoi, puta noa i ngā mākete o te ao, he maha ngā wā ka whakapoauau ngā kaihoko, ngā miihini, me ngā kaiwhakahaere kaupapa i ngā momo tikanga whakamātautau me ngā waeine ine. Mā te mārama ki te rerekētanga i waenga i te HRC (pakaritanga Rockwell) me te HV (pakaritanga Vickers), me pēhea te whakamārama i ēnei uara, ka pā nui ki tō whiringa rauemi, ki te whiriwhiringa utu, me ngā tumanakohanga mahi kakahu.

He aha te take e aro nui ai ngā kiritaki ki te hurihanga mārō?

He rerekē ngā waeine mārō e pai ana ki ngā ahumahi me ngā rohe rerekē. Hei tauira:

He maha ngā wā ka tono ngā kaihoko o Amerika me Ūropi i ngā uara Rockwell C (HRC).

Tērā pea ka pai ake ki ngā whare wānanga Āhia me ngā whare hangarau ngā raraunga Vickers (HV), inā koa mō ngā aromatawai moroiti.

Hei kaiwhakarato ao mō ngā pereti whakamau mata pakeke, he maha ngā pātai ka pā mai ki a Wodon pēnei i:

"Mēnā ko tePereti kakahu CCO"E 60 HRC te whakatauranga, he aha te pakeke Vickers e rite ana?"

Ehara i te mea he tātaitai noa iho te mea e hiahiatia ana hei whakautu i tēnei—engari me mārama ki ngā rerekētanga o ngā mātāpono whakamātautau me ngā hanganga rauemi.

Te Mārama ki te HRC me te HV: Ngā Tikanga Whakamātautau Whakamārama

1. Te Pakari o Rockwell C (HRC)

Ka ine i te hohonutanga o te kōhao i puta mai i tētahi koeko taimana i raro i tētahi kawenga matua.

He tere, he whai hua hoki mō te aromatawai i te pakeketanga o te matawhānui, inā koa mō ngā hua maitai.

He mea noa i roto i ngā whakamātautau raina whakaputa o ngā mata pereti kakahu.

2. Te Pakari o Vickers (HV)

Ka whakamahi i te kōhao piramiti taimana i raro i ngā kawenga iti ake.

Ka ine i te roa whakarara o te kōhao mā te tātaritanga whatu.

He tino pai mō te tirotiro i ngā rohe moroiti, inā koa te paparanga mārō, ngā matūriki chromium carbide takitahi rānei.

Ahakoa he tika ngā mea e rua, he rerekē ngā mahi a rāua: e whakaata ana te HRC i te pakeketanga whānui o te mata, ko te HV ia e taea ai te homai māramatanga ki te pakeketanga moroiti me te kounga o te carbide.

HRC ki HV: Ngā Awhe Tahuritanga Noa mō ngā Pereti Kākahu Whakakikorua Chromium Carbide

Anei tētahi ripanga tahuritanga māmā ake i runga i ngā raraunga whakamātautau mai i ngā pereti kakahu hiato:

⚠ Kia mōhio: He whakatau tata noa iho ēnei uara. Kāore i te tino tika te tahuritanga tika takitahi nā te rerekētanga o ngā tikanga whakamātautau me te hanganga rauemi paparanga.

He aha e kore ai e taea te huri tika i te HRC ki te HV?

He maha ngā take matua:

Ngā Tikanga Whakamātautau Rerekē

Ka whakamahia e te HRC te ine hohonu; ka whakawhirinaki te HV ki ngā whakarara whatu.

He rerekē ngā āhua o te kōhao, ngā momo kawenga, me te kapinga o te wāhi whakamātautau.

He mea nui te hanganga rauemi

A pereti kakahu rua-whakarewakei roto ngā matūriki chromium carbide mārō kua whakauruhia ki roto i te maitai ngawari.

Ka rerekē rawa te mārō i waenga i te mata, te raro whenua, me te rauemi turanga.

Ngā Rerekētanga a te Kaihanga

Ka pāngia ngā hua o ngā whakamātautau e ngā hanganga koranu rerekē, ngā tikanga whakarewa, me ngā maimoatanga wera.

Ahakoa i roto i te puranga kotahi o te pereti kakahu chromium carbide, ka taea e ngā pānui HV te awhe mai i te 600 ki te 1800, i runga i te wāhi e whakamātautau ai koe.

He inenga nui te pakeke, engari he wāhanga noa iho tēnei o te panga ina whiriwhiria te pereti kakahu whakakikorua chromium carbide tika. Mā te mārama ki te rerekētanga i waenga i te HRC me te HV, me pēhea te whakamārama tika i a rāua, ka tika ake ngā tumanakohanga mahi me ngā whakataunga tono pai ake.

Mena kāore koe i te tino mōhio ko tēhea whakatakotoranga pakeke e tika ana mō ō āhuatanga mahi, kōrero ki tā mātou tīma—ka taea e mātou te whakarato i ngā raraunga whakamātautau taipitopito me ngā taunakitanga e hangai ana ki te tono kua whakaritea mō ō wero kakahu.
