He Pūwero Tino te Kowiri tira?

Tirohanga Whānui
He rauemi rongonui te kowiri tira i roto i ngā ahumahi maha, tae atu ki te hanga, te motuka, me te rererangi. Nā ōna āhuatanga ātete-waikura me tōna pakari, he mea pai rawa atu mō ngā mahi maha. Heoi, ko tētahi pātai e ara ake ana ko "he pūwero te kowiri tira". Ko te whakautu tika, kāore te kowiri tira noa i te pūwero.
I roto i tēnei pou rangitaki, ka tūhuratia e mātou te kaupapa o te pūngao i roto i te maitai kore waikura, ā, ka whakatauhia mēnā he rauemi pūngao.

1. He aha te Kowiri tira?

Tuatahi, me mōhio tātou he aha te mea he kowiri tira?
Ko te maitai kore waikura he momo maitai kei roto i te 10.5% te iti rawa o te chromium. Tērā pea ka tāpirihia ētahi atu huānga, pērā i te nikara, te moripenema, me te taitāne, hei whakapai ake i ōna āhuatanga ātete ki te waikura. E mōhiotia ana te maitai kore waikura mō tōna kaha nui, tōna roa, me tōna ātete ki te waikura, ā, he mea pai mō te whakamahi i roto i ngā taiao uaua.

Ae, he maha ngā momo maitai kore waikura, he āhua motuhake me ngā āhuatanga motuhake o ia momo. Pērā i te maitai kore waikura Austenitic, he kore-aukume, ā, he tino ātete ki te waikura, ko te maitai kore waikura ferritic ia he aukume, ā, he iti ake te ātete ki te waikura.

2. Te Pūngao i roto i ngā Rauemi

Kātahi ka hiahia tātou ki te mōhio he aha te Porosity.
I roto i te poto, ko te Porosity te noho mai o ngā āputa, ngā pūwero rānei i roto i tētahi rauemi. Ka taea e ngā rauemi pūwero te mimiti i ngā wai me ngā hau, ka pā ki ō rātou āhuatanga me te roa. Tērā pea he āhua noho o ētahi rauemi te porosity, pērā i te rakau, i te hautai rānei, he hua rānei nō ngā tukanga hangahanga, pērā i te whakarewa, te whakarewa rānei.

Ka pā nui te noho mai o te porosity ki ngā āhuatanga ā-pūkaha o tētahi rauemi, pērā i te kaha, te ngāwari, me te pakari. Tērā pea ka ngāwari ake te waikura o ngā rauemi porosity, nā te mea ka taea e te noho mai o ngā āputa te hanga ara mō ngā mea waikura ki te uru ki roto i te rauemi.

3. Te Pūngao i roto i te Kowiri tira

Ka taea e te rino kore waikura te porous nā te maha o ngā āhuatanga, tae atu ki ngā tukanga hangahanga ngoikore, te pānga ki ngā taiao waikura, me te aroaro o ngā poke. Ko te momo porous e tino kitea ana i roto i te rino kore waikura ko te porous intergranular, e puta mai ana i te maturuturunga o ngā carbides ki ngā rohe kōpaka i te wā e whakarewahia ana.

Ka taea e te porosity intergranular te whakaiti i te ātete ki te waikura o te maitai kore waikura, me te pā ki ōna āhuatanga hangarau. Ko ētahi atu momo porosity ka puta pea i roto i te maitai kore waikura ko te porosity i puta mai i te hauwai me te wehenga dendritic.

4. Te Whakamātautau mō te Porosity i roto i te Kowiri tira

He maha ngā tikanga hei whakamātautau i te pūngao o te maitai kore waikura, tae atu ki te tirotiro ā-kanohi, te whakamātautau urunga wai, me te whakaahua hihi-X. Ko te tirotiro ā-kanohi ko te tirotiro ā-kanohi i te mata o te rauemi mō ngā tohu o te pūngao, pērā i ngā āputa, ngā kapiti rānei. Ko te whakamātautau urunga wai ko te paninga i tētahi wairewa urunga ki te mata o te rauemi, kātahi ka whakamahi i tētahi kaiwhakawhanake hei whakaatu i ngā hapa o te mata.

Ko te hihi-X he tikanga whakamātautau kore-whakangaro e whakamahi ana i ngā hihi-X hei whakaputa whakaahua o te hanganga o roto o tētahi rauemi. He tino whai hua tēnei tikanga mō te kite i te pūngao kei raro i te mata o te rauemi.

5. Ngā Whakamahinga o te Kowiri tira kore-porous

He mea nui te kowiri tira kore-pūpū i roto i ētahi ahumahi, tae atu ki te tukatuka kai, te rongoā, me ngā taputapu hauora. Nā te mata kore-pūpū o te kowiri tira ka māmā te horoi me te horoi, ā, he rauemi pai mō te whakamahi i ngā taiao e tino hiahiatia ana te akuaku.

E whakamahia whānuitia ana hoki te kowiri tira i roto i te hanganga o ngā tipu matū me te hinu-matū, ina pāngia e ngā taiao waikura kino. He mea nui te kowiri tira kore-porous i roto i ēnei mahi kia ātete ai te rauemi ki te waikura, ā, ka taea hoki te tu atu i ngā āhuatanga kino.

Whakamutunga

Hei whakamutunga, ka taea e te rino kore waikura te porowhita nā te maha o ngā āhuatanga, tae atu ki ngā tukanga hangahanga ngoikore, te pānga ki ngā taiao waikura, me te aroaro o ngā poke. Ka taea e te porowhita o te rino kore waikura te whakaiti i tōna ātete ki te waikura, me te pā ki ōna āhuatanga miihini.

He Pātai Auau mō te Kowiri tira Porous?

1. He aha te maitai kore waikura, ā, he aha i whakamahia ai?

Ko te maitai kore waikura he momo maitai kei roto i te iti rawa o te 10.5% te chromium, e whakarato ana i ngā āhuatanga ahurei o te rauemi, tae atu ki te ātete ki te waikura, te kaha, me te roa. He whānuitia te whakamahinga i roto i te whānuitanga o ngā mahi, tae atu ki te hanga, te kawe waka, ngā taputapu hauora, me ngā taputapu o te whare.

2. Ka taea e te maitai kore waikura te noho pūngoi?

Āe, i raro i ētahi āhuatanga, ka taea e te maitai kore waikura te porous. Ka puta te porous i roto i te maitai kore waikura i te wā o te tukanga hanga, inā koa i te wā whakarewa. Ko ētahi atu āhuatanga ka taea te whakararu ko te pānga ki ngā taiao waikura me te noho mai o ngā poke i roto i te rauemi.

3. He aha te pānga o te pūngao ki ngā āhuatanga o te maitai kore waikura?

Ka taea e te pūngao te whakaiti i te ātete waikura o te maitai kore waikura, ka ngawari ake ai te waikura. Ka taea hoki e ia te ngoikore o te rauemi, ka whakaiti i tōna kaha me tōna roa.

4. Me pēhea te kimi i te porosity i roto i te maitai kore waikura?

He tikanga māmā noa te tirotiro ā-kanohi hei whakamātautau i te pūngao, engari kāore pea e whai hua ki te kite i te pūngao kei raro i te mata o te rauemi. He tikanga whai hua ake te whakamātautau i te pūngao wai me te whakaahua hihi-X, nā te mea ka taea e rātou te kite i ngā hapa o te mata me te pūngao kei raro i te mata o te rauemi.

5. Kāore he pūwero o te kowiri tira katoa?

Kāo, ehara i te mea he kore-pūwero te rino kore-waikura katoa. He nui ake te pūwero o ētahi momo rino kore-waikura i ētahi atu, i runga i te hanganga me te tukanga hanga. Hei tauira, ko te rino kore-waikura 304 he kore-pūwero i te nuinga o te wā, ko te rino kore-waikura 316 ia ka ngawari ake te pūwero nā te nui ake o te molybdenum.

6. He aha ngā ahumahi e whakawhirinaki ana ki te maitai kore-porous?

He mea nui te kowiri tira kore-porous i roto i ētahi ahumahi, he mea nui te akuaku me te ātete ki te waikura. Kei roto i ēnei ahumahi ko te tukatuka kai, te rongoā, me ngā taputapu hauora. He mea whakamahi whānuitia hoki te kowiri tira i roto i te hanganga o ngā tipu matū me te hinu-matū, ina pāngia e ngā taiao waikura kino.

7. Me pēhea te ārai i te porosity i roto i te maitai kore waikura?

Ka taea te ārai i te pūngao o te maitai kore waikura mā te whakamahi i ngā tikanga whakarewa tika, me te whakarite kia kore he poke o te rauemi. He mea nui anō hoki kia tiakina te maitai kore waikura mai i te pānga ki ngā taiao waikura, pērā i te waikawa, te tote, me ētahi atu matū.

Nō reira, he aha te momo maitai kore waikura e rapu ana koe? He maitai kore waikura porous, he maitai kore waikura porous rānei?
