Ko ngā painga o ngā taputapu carbide pania he penei:
(1) He tino pakeke te rauemi paninga o te paparanga mata, ā, he ātete ki te kakahu. Ki te whakatauritea ki te kāpira sima kāore i pania, ka taea e te kāpira sima pania te whakamahi i ngā tere tapahi teitei ake, ā, ka pai ake te pai o te tukatuka, ka taea rānei te whakanui ake i te roa o te ora o te taputapu i te tere tapahi kotahi.
(2) He iti te tauwehenga o te waku i waenga i te rauemi pania me te rauemi tukatuka. Ki te whakatauritea ki te kāpira sima kāore i pania, ka whakaitihia te kaha tapahi o te kāpira sima pania ki tētahi taumata, ā, ka pai ake te kounga o te mata tukatuka.
(3) Nā te pai o te mahi whānui, he pai ake te whānui o te whakamahinga o te maripi karawiti pania, ā, he whānui ake te whānuitanga o te whakamahinga. Ko te tikanga e whakamahia whānuitia ana mō te paninga karawiti sima ko te whakatakotoranga kohu matū pāmahana teitei (HTCVD). Ka whakamahia te whakatakotoranga kohu matū plasma (PCVD) hei pani i te mata o te karawiti sima.
Ngā momo paninga o ngā mīhini mira kāpira sima:
Ko ngā rauemi paninga e toru e tino kitea ana ko te titanium nitride (TiN), te titanium carbonitride (TiCN) me te titanium aluminide (TiAIN).
Ka taea e te paninga titanium nitride te whakanui ake i te pakeketanga me te ātete ki te kakahu o te mata o te taputapu, te whakaiti i te tauwehenga waku, te whakaiti i te whakaputanga o te taha hangai, me te whakaroa i te roa o te ora o te taputapu. He pai ngā taputapu paninga titanium nitride mō te tukatuka i te maitai iti-koranu me te maitai kore waikura.
He hina te mata o te paninga titanium carbonitride, he teitei ake te pakeke i te paninga titanium nitride, ā, he pai ake te ātete ki te kakahu. Ki te whakatauritea ki te paninga titanium nitride, ka taea te tukatuka i te taputapu paninga titanium carbonitride i te tere whāngai me te tere tapahi nui ake (40% me te 60% teitei ake i te paninga titanium nitride), ā, he teitei ake te tere tango rauemi mahi. Ka taea e ngā taputapu paninga titanium carbonitride te tukatuka i ngā momo rauemi mahi.
He hina, he mangu rānei te paninga titanium aluminide. Ko te nuinga o te wā ka pania ki te mata o te turanga taputapu carbide sima. Ka taea tonu te tukatuka ina tae te pāmahana tapahi ki te 800 ℃. He pai mō te tapahi maroke tere-tere. I te wā tapahi maroke, ka taea te tango i ngā maramara i te wāhi tapahi ki te hau kōpeke. He pai te titanium aluminide mō te tukatuka i ngā rauemi pakarukaru pēnei i te maitai whakapakeke, te koranu titanium, te koranu nikara, te rino maka me te koranu konumohe silicon teitei.
Te paninga o te mīhini mira kāpia sima:
E kitea ana hoki te ahunga whakamua o te hangarau paninga taputapu i roto i te whaihua o te paninga nano. Ko te paninga rau rau o ngā paparanga rauemi me te matotoru o ētahi nanometer ki runga i te rauemi turanga taputapu ka kiia ko te paninga nano. He tino iti te rahi o ia matūriki o te rauemi paninga nano, nō reira he tino roa te rohe kōpaka, he pakeke teitei te pāmahana. , Kaha me te pakari pakaru.
Ka taea e te pakeke Vickers o te paninga nano te eke ki te HV2800～3000, ā, ka pai ake te ātete ki te kakahu mā te 5%～50% i tērā o ngā rauemi maikorona. E ai ki ngā pūrongo, i tēnei wā, e 62 ngā paparanga o ngā taputapu paninga me ngā paninga tauutuutu o te titanium carbide me te titanium carbonitride me te 400 ngā paparanga o ngā taputapu paninga nano TiAlN-TiAlN/Al2O3 kua whakawhanakehia.
Ki te whakaritea ki ngā paninga mārō o runga ake nei, ko te whanariki (MoS2, WS2) i pania ki te maitai tere-rahi ka kiia he paninga ngohengohe, e whakamahia ana mō te tapahi i ngā koranu konumohe kaha-teitei, ngā koranu titanium me ētahi konganuku onge.
Mena he hiahia āu, tēnā whakapā mai ki a MSK, ka tere te tuku taputapu rahi paerewa me te mahere taputapu kua whakaritea mō ngā kiritaki.
