Ko ngā rauemi taputapu kāpira sima noa ko te kāpira sima e ahu mai ana i te kāpira tungsten, te kāpira sima e ahu mai ana i te TiC(N), te kāpira sima me te TaC (NbC tāpirihia), me te kāpira sima tino pai rawa. Ko te mahi a ngā rauemi kāpira sima e whakatauhia ana e ngā wāhanga whakapakari kua tāpirihia.
Carbide Simented me te TaC Tāpiri (NbC)
He tikanga whai hua te tāpiri i te TaC (NbC) ki te kāpira sima hei whakarei ake i tōna mahi. I roto i ngā koranu TiC/Ni/Mo, mā te whakakapi i tētahi wāhanga o te TiC ki ngā kāpira pēnei i te WC me te TaC, e pai ake ai te pakari, ka whakapai ake i te mahi a te kāpira sima, ā, ka whānui ake hoki tōna whānuitanga tono. Mā te tāpiri i te WC me te TaC ka whakarei ake i:
● Te pakari
● Te tauwehenga rapa
● Ātete ki te whakarerekētanga kirihou
● Kaha pāmahana teitei
Ka whakapai ake hoki i te kawe wera me te ātete ki ngā ru wera, kia pai ake ai te taputapu mō te tapahi haukoti. I roto i ngā koranu WC-Co, ka taea te whakapai ake i te mahi mā te tāpiri i te 0.5% ki te 3% (wāhanga papatipu) o ngā warowaihā pēnei i te TaC, NbC, Cr3C2, VC, TiC, HfC rānei. Ko ngā whāinga matua ko:
● Te whakapai ake i te witi
● Te pupuri i tētahi hanganga tioata ōrite, me te kore e nui te whakakōhatu anō
● Te whakanui ake i te pakeke me te ātete ki te kakahu me te kore e whakaiti i te pakari
Hei tāpiri, ka whakarei ake ēnei tāpiringa:
● Te pakeketanga o te pāmahana teitei
● Kaha pāmahana teitei
● Ātete waikura
I te wā e tapahi ana, ka puta he kiriata waikura pakari, e whakaea ana i a ia anō, e ātete ana ki te piripiri me te pakaru o te kakahu i te wā e miihinihia ana ētahi konganuku, ētahi koranu rānei. Ka whakapai ake tēnei i te ātete kakahu o te taputapu, ā, ka whakanui ake i tōna kaha ki te ātete i te kakahu o te rua me te kakahu o te taha. Ka nui ake te kitea o ēnei painga i te pikinga ake o te ihirangi cobalt i roto i te carbide sima.
● Ka taea e te waro sima me te 1% ki te 3% (wāhanga papatipu) TaC (NbC) te miihini i ngā rino maka maha, tae atu ki te rino maka tino mārō me te rino maka koranu.
● He maha ngā whakamahinga o ngā konukōre iti-kobalt me te 3% ki te 10% (wāhanga papatipu) TaC (NbC), pērā i te YG6A, YG8N, me te YG813. Ka taea e rātou te tukatuka:
Rino maka matao
Rino maka ngawari
Ngā konganuku kore-ferrous
Ngā rauemi uaua ki te mīhini pērā i te maitai kore waikura, te maitai whakapakeke, me ngā koranu pāmahana teitei
E mōhiotia whānuitia ana ēnei ko ngā koranu whānui (YW). Mā te whakanui ake i te nui o te cobalt ka whakanui ake i te kaha me te pakari o tēnei momo carbide sima, ka pai ai mō te miihini taratara me te tapahi whakaroa o ngā rauemi uaua ki te miihini. Ko ngā whakamahinga ko:
● Te whakakoi i ngā whakarewa me ngā hanga rino nunui
● Te huri, te whakatakoto, me te mira i te maitai austenitic me ngā koranu ātete-wera
● Te mīhini me ngā koki rake nui, ngā wāhanga tapahi nui, me ngā tere waenga ki te iti
● Te hurihanga matapōkere i ngā mīhini hurihanga aunoa, ā-haurua-aunoa, me ngā mīhini hurihanga maha-taputapu
● Te hanga wiri, te oumu taputapu, me ētahi atu taputapu he kaha te mata tapahi**
I roto i ngā koranu WC-TiC-Co, ka nui ake te aro o te TiC ki te pakaru wera, ka nui ake te pakarukaru. Mā te tāpiri i te TaC ki ngā koranu WC-Ti-Co iti-TiC, nui-kobalt ka whakapai ake i:
● Te pakari
● Ātete wera
● Ātete waikura
Ahakoa ka whakaitihia e te TiC te ātete ki ngā ru wera, ka whakaea tēnei e te TaC, ka pai ai te koranu mō ngā mahi mira. Ka taea te whakakapi i te TaC mā ngā momo mea iti ake te utu pērā i te NbC, ngā warowaihā Hf-Nb rānei (te wāhanga papatipu: Hf-60%, Nb-40%). I roto i ngā koranu TiC-Ni-Mo, mā te tāpiri i te TiN, WC, me te TaC i te wā kotahi ka nui ake te whakapai ake:
● Te mārō
● Kaha piko
● Ātete waikura
● Te kawe wera
i ngā pāmahana teitei (900–1000°C).
Carbide Simeni Tino Pai
Mā te whakamahine i ngā kirikiri o te karāhe sima ka whakaitihia te rahi o te āhua mārō, ka whakanuia te horahanga o te mata o ngā kirikiri āhua mārō me te kaha o te here i waenga i ngā kirikiri. Ka tohatoha ōrite ake te āhua here huri noa i a rātou, ka whakapai ake:
Te pakeketanga
Ātete kakahu
Mā te whakanui ake i te nui o te cobalt ka whakanui ake i te kaha piko. Ko te carbide sima tino pai, he mea hanga mai i ngā matūriki WC me Co tino iti, ka whakakotahi i:
Te pakeketanga teitei o te carbide sima
Te kaha o te maitai tere-teitei
Ngā whakataurite i te rahi o te witi:
Karāhe sima noa: 3–5 μm
Karāhe sima pai-kikokiko whānui: ~1.5 μm
Ngā koranu iti-maikoron: 0.5–1 μm
Karāhe sima tino pai rawa: te rahi o te witi WC i raro i te 0.5 μm
Ka whakapai ake te whakamahine o te witi:
Te pakeketanga
Ātete kakahu
Kaha piko
Ātete ki te pakaru
Te pakeketanga o te pāmahana teitei
Ki te whakatauritea ki te kāpira sima noa o te hanganga kotahi, ka tukuna e te kāpira sima tino pai:
Te pikinga o te pakeke neke atu i te 2 HRA
Te pikinga o te kaha piko o te 600–800 MPa
Ngā āhuatanga noa:
Te nui o te konupora: 9%–15%
Pakari: 90–93 HRA
Kaha piko: 2000–3500 MPa
Ko ngā momo i hangaia i Haina ko te YS2 (YG10H, YG10HT), YM051 (YH1), YM052 (YH2), YM053 (YH3), YD05 (YC09), YD10 (YG1101), B60, YG610, YG643, me te YD05. Nā te mea he tino angiangi ngā kakano, ka taea te huri i te karawiti sima tino angiangi ki ngā mata tapahi koi rawa me te iti o te taratara o te mata, he mea tino pai mō ngā taputapu tino tika pēnei i:
Ngā mea whakarara
Ngā Kaimahi Reamer
Ngā oumu tino tika
He tino pai ki te mahi miihini me te iti o te hohonu o te tapahi me te whāngai. He pai hoki mō ngā taputapu iti pēnei i:
Ngā wiri iti
Ngā mīhini mira iti
Ngā poroporo iti
Ngā oumu iti
Hei whakakapi i ngā taputapu maitai tere-rahi, ko tōna roanga mahi he 10–40 ngā wā roa ake, ā, tera pea neke atu i te 100 ngā wā. He tino pai ngā taputapu karāti sima tino pai mō te miihini:
Ngā koranu pāmahana teitei e hangai ana ki te rino me te nikara
Ngā koranu titanium
Ngā maitai kore waikura ātete wera
Ngā rauemi i rehuhia, i whakarewahia, i whakakikoruatia (hei tauira, ngā paura rino, nikara, cobalt, paura koranu rere-ake tino mārō, raupapa cobalt-chromium-tungsten)
Ngā maitai tino kaha
Ngā maitai whakapakeke
Ngā rauemi pakeke-teitei pērā i te rino whakarewa-konupora-teitei me te rino whakarewa-nikara
Ina miihinihia ngā rauemi uaua ki te miihini, e 3–10 ngā wā ka roa ake tōna roa i tērā o te waro sima noa.
