He aha i pai ake ai te mahi a ngā pereti whakakikorua Chromium Carbide i te maitai kakahu noa

Ko te kakahu whakakoi i puta mai i ngā matūriki kohuke mārō tētahi o ngā tikanga pirau tino kino i roto i ngā ahumahi taumaha pērā i te keri maina, te sima, te whakaputa hiko, me te mahi whakarewa. Kia oti ngā wāhanga hanganga pērā i tengā awaawa, ngā pekepeke, ka pakaru ngā tēpu huri, me ngā raina kawe, ka heke te whai huatanga o ngā taputapu, ka piki ake ngā utu tiaki, ā, ka puta ngā kati mahi kāore i te whakamaheretia.

Hei whakaiti i ēnei wero, kua noho ko ngā pereti kakahu chromium carbide hei otinga paerewa mō te umanga, he mea nui mō tōna pakeke teitei, tōna hononga whakarewa kaha, me tōna roa o te ora ratonga. Ahakoa rā, he nui tonu ngā rerekētanga mahi i waenga i ngā kaihanga. Ka whakaratohia e tēnei pepa he aromatawai whakarewa me te whakamātautau hei whakamārama he aha a WodonNgā pereti kakahu Chromium Carbide Overlay (CCO)he ātete pai rawa atu ki te kakahu ina whakaritea ki ngā maitai kakahu tuku iho me ngā pereti kakahu whakamaroke whānui.

Te Hanganga Matū me te Hanganga Āhuatanga

Ko te ātete ki te kakahu o tētahi pereti kakahu hiato e whakahaeretia ana e te hanganga matū o te paparanga me te hanganga iti e puta mai ana. He mea hanga ngā pereti Wodon me ngā taumata waro (C) me te chromium (Cr) kia tino taurite, kia tino nui ai te maturuturunga o ngā warowaiha whai chromium i te wā e totoka ana.

Te Hanganga o te Wāhanga Waro – Ka tauhohe te waro ki te chromium hei hanga i ngā waro Cr₇C₃ hexagonal tuatahi, ka whakaatu i ngā uara pakeke moroiti tae atu ki te HV1800, he teitei ake i te papa maitai.

Te Pakari o te Matrix – Ka tautoko te pereti turanga maitai ngawari i te pakari me te mimiti pānga, ā, ka whakarite te paparanga kia pakari te mata. Ka puta he pereti kakahu rua-whakarewa mai i tēnei hanganga paparanga-rua, he kaha, he pakari hoki.

Ngā Tikanga Whakapūmau me te Whakamātautau mō ngā Pereti Kakahu Bimetallic

He rerekē ki ngā maitai hanganga, ki ngā maitai pūwero rānei, e whakahaeretia ana e ngā whakaritenga ā-ao kotahi (pēnei i ngā paerewa ASTM, EN, GB rānei),ngā pereti kakahu bimetallickāore i te wātea he paerewa ā-ao whānui i tēnei wā.

Nā reira, ko te tikanga tino whai mana hei whakamana i te mahi kakahu ko te whakamātautau pakū o te wira rapa onepu maroke. Ka tāruatia e tēnei whakamātautau paerewa te pakū o te tinana-toru mā te pēhi i te wira rapa ki te mata kakahu me te whāngai i te onepu silica maroke i te tere whakahaeretia. Mā te tuhi i te ngaronga papatipu o ngā tauira, ka taea te ine i te ātete kakahu whanaunga i runga i te whakaaro whaitake me te whakaputa anō.

Ngā tikanga whakamātautau:

Te Ritenga o ngā Tauira – I tapahia ngā tauira mai i a Wodon, mai i ngā pereti kakahu kawemai, me ngā pereti kakahu ā-whare kia ōrite ngā rahi.

Waenga Whakakorikori – I whakamahia te onepu kiripaka koki hei whakatauira i ngā āhuatanga whakakorikori tino kaha.

Utaina me te Roanga – I tukuna he kawenga pumau mō te 45 meneti i raro i ngā taiao ōrite.

Mā tēnei huarahi ka whakakorea te whakaaro ā-ira, ā-whakahaere rānei, kia mōhio ai ko te mahi kakahu i inehia e whakaata ana i ngā āhuatanga rauemi anake o ia pereti.

Ngā Hua Whakamātautau me te Tātari Whakataurite

Te whakaheke taumaha i muri i te 45 meneti:

Pereti kakahu rakau: 0.148 karamu

Pereti kakahu kawemai: 0.229 – 0.252 karamu

Pereti kakahu ā-whare: 0.371 – 0.399 karamu

E whakaū ana tēnei rangahau he nui ake te pai o ngā pereti kakahu chromium carbide i hangaia mā roto i ngā tukanga whakakikorua matatau i roto i ngā taiao whakakoi.
