Me pēhea te whakarei ake a te maimoatanga nitriding i te ātete ki te kakahu o ngā mekameka roera?

1. Whakataki

I roto i te ahumahi hou, he wāhanga nui ngā mekameka roera hei tuku, ā, e whakamahia whānuitia ana i roto i ngā taputapu mīhini maha. Ko te kounga o tā rātou mahi e pā tika ana ki te whai huatanga o te mahi me te roa o te ratonga o ngā taputapu. Ko te ātete ki te kakahu tētahi o ngā tohu mahi matua omekameka roera, ā, mā te maimoatanga nitriding, hei hangarau whakapakari mata whai hua, ka taea te whakapai ake i te ātete kakahu o ngā mekameka roera.

2. Te kaupapa o te maimoatanga nitriding
Ko te maimoatanga nitriding he tukanga maimoatanga wera mata e āhei ai ngā ngota hauota ki te uru ki roto i te mata o te mea mahi i tētahi pāmahana me roto i tētahi reo motuhake hei hanga i tētahi paparanga nitride pakeke-teitei. I te nuinga o te wā ka mahia tēnei tukanga i te pāmahana o te 500-540℃, ā, ka roa mō te 35-65 hāora. He papaku te hohonutanga o te paparanga nitriding, hei tauira, ko te hohonutanga o te paparanga nitriding o te maitai chromium-molybdenum-konumohe he 0.3-0.65mm noa iho. Ka taea te whakapai ake i te pakeketanga o te mata o te mea mahi i muri i te maimoatanga nitriding ki te 1100-1200HV (he rite ki te 67-72HRC).

3. Te tukanga whakanitoria
Ko te tukanga whakahāngai hauota ko ngā mahi matua e whai ake nei:
Te whakamahana: Whakamahanahia te mekameka roera ki te pāmahana nitriding, i waenganui i te 500-540℃.
Te whakamarumaru: Kia tae ki te pāmahana nitriding, kia mau ki tētahi wā whakamarumaru kia taea ai e ngā ngota hauota te uru katoa ki te mata o te mahi.
Whakamatao: Kia oti te whakahāngai hauota, whakamatao mārire te mea mahi kia kore ai e pāngia e te ahotea o roto.
I te wā o te tukanga whakanitiritiri, ka whakamahia he reo hau kei roto te hauota, pērā i te haukini. Ka pirau te haukini i te pāmahana teitei hei whakaputa i ngā ngota hauota, ka uru ki roto i te mata o te mea mahi hei hanga i tētahi paparanga nitride. Hei tāpiri, hei whakapai ake i te pānga whakanitiritiri, ka tāpirihia ētahi huānga koranu pērā i te konumohe, te titanium, te vanadium, te tungsten, te molybdenum, te chromium, me ētahi atu ki te maitai. Ka taea e ēnei huānga te hanga i ngā matū pumau me te hauota, ka whakapai ake i te pakeke me te ātete ki te kakahu o te paparanga whakanitiritiri.

4. Te tikanga mō te whakarei ake i te ātete kakahu o ngā mekameka roera mā te nitriding
(I) Te whakapai ake i te mārō o te mata
I muri i te whakanitiritiri, ka hangaia he paparanga nitride tino pakeke ki runga i te mata o te mekameka roera. Ka taea e tēnei paparanga nitride te ātete pai i te kakahu o ngā kawenga o waho, me te whakaiti i ngā karawarawa mata me te hohonu o te kakahu. Hei tauira, ka taea e te pakeke o te mata o te mekameka roera kua whakanitiritiri te eke ki te 1100-1200HV, he nui ake i te pakeke o te mata o te mekameka roera kāore i rongoatia.
(II) Te whakapai ake i te hanganga moroiti o te mata
Ka taea e te maimoatanga nitriding te hanga i ngā matūriki nitride angiangi ki runga i te mata o te mekameka roera. Ka tohatohahia ēnei matūriki ki roto i te matrix, ka taea ai te whakapai ake i te ātete kakahu o te mata me te ātete ngenge. Hei tāpiri, mā te hanganga o te paparanga nitriding ka taea hoki te whakapai ake i te hanganga moroiti o te mata o te mekameka roera, te whakaiti i ngā hapa me ngā kapiti o te mata, ā, nā reira ka whakapai ake i te mahi whānui o te mekameka roera.
(III) Te whakapai ake i te ātete ki te ngenge
Ehara i te mea ka taea e te maimoatanga nitriding te whakapai ake i te pakeke me te ātete kakahu o te mata o te mekameka roera anake, engari ka taea hoki te whakapai ake i tōna ātete ngenge. Nā te mea ka taea e te paparanga nitriding te whakamarara i te ahotea me te whakaiti i te kukū ahotea, ā, ka whakaiti i te tūponotanga o te puta me te whānui o te pakaru ngenge. Hei tauira, i roto i te rangahau o ngā mekameka taima me ngā mekameka tuku motopaika, i kitea kua tino pai ake te pakeke o te mata me te ātete ngenge o te rakau pine maitai kua tineihia me te whakamahanahia kua tukinotia ki te carbonitriding.
(IV) Whakapai ake i te ātete ki te waikura
Ka hangaia he paparanga nitride matotoru ki runga i te mata o te mekameka roera i muri i te maimoatanga nitride. Ka taea e tēnei paparanga nitride te ārai i te pirau o ngā mea waikura o waho, me te whakapai ake i te ātete ki te waikura o te mekameka roera. He mea nui rawa tēnei mō ngā mekameka roera e mahi ana i roto i ngā taiao uaua, ā, ka taea hoki te whakaroa i tōna roanga mahi.

5. Te whakamahinga o te maimoatanga nitriding i roto i te hanga mekameka roera
(I) Whakapai ake i te roa o te mahi a ngā mekameka roera
Ka taea e te maimoatanga nitriding te whakapai ake i te ātete ki te kakahu me te ātete ki te ngenge o ngā mekameka roera, ā, ka roa ake te ora o te mahi. Hei tauira, i muri i te maimoatanga nitriding, kua neke atu i te rua te roa o te ora o te mekameka kawe kaha-teitei, ā, he ātete ki te kakahu. Nā te mea ka taea e te mekameka roera i muri i te maimoatanga nitriding te ātete pai ki te whakaputa i ngā pakaru kakahu me te ngenge i te wā e whakamahia ana, ā, ka whakaitihia te auau o te tiaki me te whakakapinga.
(II) Whakapai ake i te pono o ngā mekameka roera
He nui ake te pakeke o te mata o te mekameka roera i muri i te maimoatanga nitriding me te ātete ki te ngenge, ā, he pai ake te pono i te wā e whakamahia ana. Ahakoa e mahi ana i raro i te kawenga nui me te taiao uaua, ka taea e te mekameka roera te pupuri i te mahi pai me te whakaiti i te tūponotanga o te rahunga. He mea tino nui tēnei mō ētahi taputapu he nui ngā whakaritenga pono, ā, ka taea te whakapai ake i te whai huatanga o te whakahaere o te taputapu.
(III) Whakaitihia te utu tiaki o ngā mekameka roera
I te mea ka taea e te maimoatanga nitriding te whakapai ake i te roa o te mahi me te pono o ngā mekameka roera, ka taea hoki te whakaiti i te utu tiaki. Mā te whakaiti i te auau o te tiaki me te whakakapinga, ehara i te mea ka taea te penapena i te wā me te utu mahi anake, engari ka whakaiti hoki i ngā mate ōhanga e puta mai ana i te wā kore mahi o ngā taputapu. He mea nui tēnei ki te ōhanga mō ngā umanga.
