E oo lava i le maualuga o le vevela o le tipi, o le ola faʻaaogaina o le meafaigaluega tipi e mafai ona faʻalauteleina i le ufiufi, ma faʻaitiitia ai le tau o masini. E le gata i lea, o le tipiina o mea faigaluega e mafai ona faʻaitiitia ai le manaʻomia mo le lubricating vai. E le gata e faʻaitiitia ai tau o meafaitino, ae fesoasoani foi i le puipuia o le siosiomaga.
A'afiaga o le fa'agasologa muamua ma le mae'a o le fa'apipi'iina ile gaosiga
I galuega tipi fa'aonaponei, o meafaigaluega tipi e mana'omia le maualuga o le mamafa (> 2 GPa), maualuga le vevela ma le taamilosaga faifaipea o le vevela vevela. Aʻo leʻi maeʻa le faʻapipiʻiina o le meafaigaluega tipi, e tatau ona togafitia i le faiga talafeagai.
Aʻo leʻi tipiina le faʻapipiʻiina o meafaigaluega, e mafai ona faʻaogaina auala eseese e sauniuni ai mo le faʻagasologa o le ufiufi mulimuli, aʻo faʻaleleia atili le pipii o le ufiufi. E ala i le galulue faʻatasi ma le faʻapipiʻiina, o le sauniuniga o le mea e faʻaaogaina ai meafaigaluega e mafai foi ona faʻateleina le saoasaoa o le tipi ma le fua o meaʻai, ma faʻalauteleina le ola o meafaigaluega.
O le faʻapipiʻiina o le faʻapipiʻiina (sauniuniga pito, faʻaogaina o luga ma le faʻatulagaina) o loʻo i ai foi se sao taua i le faʻaogaina o le meafaigaluega tipi, aemaise lava le puipuia o le vave faʻaogaina e ala i le faʻavaeina o le pu (faʻapipiʻiina o mea faigaluega i le pito o le meafaigaluega).
Fuafuaga faʻapipiʻi ma filifiliga
O mea e manaʻomia mo le faʻaogaina o le faʻapipiʻiina e mafai ona matua ese lava. I lalo o tulaga o masini e maualuga ai le vevela o le vevela, o uiga faʻaofuofu e teteʻe i le vevela e matua taua tele. O loʻo faʻamoemoeina o faʻaonaponei faʻaonaponei e tatau foi ona i ai uiga nei: sili ona lelei le maualuga o le vevela, faʻamaʻi faʻamaʻi, maualuga maualuga (tusa lava pe maualuga le vevela), ma microscopic toughness (plasticity) e ala i le mamanu o nanostructured layers.
Mo meafaigaluega tipiina lelei, faʻapipiʻi faʻapipiʻi faʻapipiʻi lelei ma le tufatufaina talafeagai o faʻamaʻi o totoe o ni mea taua e lua. Muamua, o le fegalegaleaiga i le va o mea faʻapipiʻi ma mea faʻapipiʻi e manaʻomia ona mafaufau i ai. Lona lua, e tatau ona i ai sina fa'atasiga la'ititi i le va o mea fa'apipi'i ma mea e fa'agaioia. O le avanoa o le pipii i le va o le ufiufi ma le mea faigaluega e mafai ona faʻaitiitia tele e ala i le faʻaaogaina o se geometry meafaigaluega talafeagai ma faʻalelei le ufiufi.
O pa'u fa'avae alumini (fa'ata'ita'iga AlTiN) e masani ona fa'aogaina e fai ma fa'alavalava meafaigaluega tipi i totonu o pisinisi tipi. I lalo o le gaioiga o le maualuga o le vevela, o nei mea faʻapipiʻi alumini e mafai ona fausia ai se mea manifinifi ma mafiafia o le alumini oxide lea e faʻafouina pea lava i le taimi o masini, puipuia le faʻapipiʻiina ma le mea faʻapipiʻi i lalo mai osofaiga faʻamaʻi.
O le maaa ma le faʻamaʻiina o le faʻamaʻiina o le faʻamaʻiina o se paʻu e mafai ona fetuunai e ala i le suia o mea alumini ma le fausaga faʻapipiʻi. Mo se faʻataʻitaʻiga, e ala i le faʻateleina o mea alumini, faʻaaogaina nano-structures poʻo micro-alloying (faʻataʻitaʻiga, faʻafefiloi ma elemene maualalo maualalo), e mafai ona faʻaleleia le faʻamaʻiina o le faʻamaʻiina o le ufiufi.
I le faaopoopo atu i le vailaʻau faʻapipiʻi o mea faʻapipiʻi, o suiga i le fausaga faʻapipiʻi e mafai ona matua aʻafia ai le faʻatinoga o le faʻaogaina. O le faʻatinoga o meafaigaluega tipi eseese e faʻalagolago i le tufatufaina atu o elemene eseese i totonu o le micro-structure coating.
I aso nei, e mafai ona tuʻufaʻatasia le tele o mea faʻapipiʻi faʻapipiʻi faʻatasi ai ma vailaʻau faʻapitoa eseese i se faʻapipiʻi faʻapipiʻi faʻapipiʻi e maua ai le faʻatinoga manaʻomia. O lenei tulaga o le a faʻaauau pea ona atiaʻe i le lumanaʻi - aemaise lava e ala i faiga faʻapipiʻi fou ma faiga faʻapipiʻi, e pei o le HI3 (High Ionization Triple) arc evaporation ma sputtering hybrid coating technology lea e tuʻufaʻatasia tolu faiga faʻapipiʻi maualuga i le tasi.
I le avea ai ma se faʻaofuofu lapotopoto atoa, faʻapipiʻi faʻavae titanium-silicon (TiSi) e ofoina atu le faʻaogaina lelei o masini. E mafai ona fa'aogaina ia fa'alavalava mo le fa'agaoioiga o u'amea ma'a'a maualuga e ese'ese i totonu o le carbide (maa'a autu e o'o atu i le HRC 65) ma u'amea maaa (core hardness HRC 40). O le mamanu o le fausaga faʻapipiʻi e mafai ona faʻafetaui e tusa ai ma faʻaoga eseese o masini. O le iʻuga, e mafai ona faʻaaogaina meafaigaluega tipi faʻapipiʻi faʻapipiʻiina o le titanium silicone mo le tipiina ma le faʻaogaina o le tele o mea faigaluega mai mea faʻapipiʻi maualuga, uʻamea maualalo i uʻamea malo ma uʻamea titanium. O su'ega tipiina maualuga i luga o mea faigaluega mafolafola (maaa HRC 44) ua fa'aalia ai e mafai ona fa'atuputeleina lona ola i le toeitiiti lua taimi ma fa'aitiitia ai le talatala o luga e tusa ma le 10 taimi.
O le fa'apipi'i fa'avae titanium-silicone fa'aitiitia ai le fa'aiila o luga. O ia fa'alavalava o le a fa'amoemoe e fa'aogaina i le fa'agaioiina ma le maualuga o le saosaoa o le tipi, maualuga le vevela ma le maualuga o le aveeseina o u'amea.
Mo nisi PVD coatings (aemaise micro-alloyed coatings), o loʻo galulue faʻatasi kamupani faʻapipiʻi faʻatasi ma le gaosiga e suʻesuʻe ma atiaʻe ni fofo faʻaogaina o luga. O le mea lea, o le faʻaleleia atili o le faʻaogaina o masini, faʻaogaina o meafaigaluega, faʻaogaina lelei, ma le fegalegaleaiga i le va o meafaitino, faʻapipiʻi ma masini e mafai, ma e mafai ona faʻaaogaina. E ala i le galulue faʻatasi ma se paʻaga faʻapolofesa faʻapolofesa, e mafai e tagata faʻaoga ona faʻateleina le faʻaogaina lelei oa latou meafaigaluega i le gasologa o latou olaga.
