Ibikoresho bya karubide bipfutse bifite ibyiza bikurikira:
(1) Ibikoresho byo gusiga ku buso bifite ubukana bwinshi cyane kandi birwanya kwangirika. Ugereranyije na karubide idasize irambitse, karubide isize irambitse yemerera gukoresha umuvuduko wo hejuru wo gukata, bityo bikanongera imikorere myiza, cyangwa bishobora kongera cyane igihe cyo gukoresha igikoresho ku muvuduko umwe wo gukata.
(2) Igipimo cy'ubushyamirane hagati y'ibikoresho bitwikiriwe n'ibikoresho bitunganywa ni gito. Ugereranyije na karubide idatwikiriwe, imbaraga zo gukata karubide itwikiriwe iragabanuka ku rugero runaka, kandi ubwiza bw'ubuso butunganywa burushaho kuba bwiza.
(3) Bitewe n'imikorere myiza, icyuma cya karubide gipfundikiye gifite ubushobozi bwo gukora ibintu byinshi kandi gifite urwego rwagutse rwo gukoresha. Uburyo bukunze gukoreshwa cyane bwo gusiga karubide ipfundikiye ni ugusiga umwuka w'ubushyuhe bwinshi (HTCVD). Gusiga umwuka w'ubushyuhe bwa plasma (PCVD) bikoreshwa mu gusiga hejuru ya karubide ipfundikiye.
Ubwoko bw'ibikoresho byo gukata karubide bikozwe muri sima:
Ibikoresho bitatu bikunze gusigwa ni titanium nitride (TiN), titanium carbonitride (TiCN) na titanium aluminide (TiAIN).
Igipfundikizo cya titanium nitride gishobora kongera ubukana no kudashira kw'ubuso bw'igikoresho, kugabanya ingano y'ubushyuhe, kugabanya umusaruro w'inkombe zubatse, no kongera igihe cy'ubuzima bw'igikoresho. Ibikoresho bya titanium nitride birakwiriye mu gutunganya ibyuma bidafite aloyi nyinshi n'ibyuma bitanduye.
Ubuso bw'igitambaro cya titaniyumu ni imvi, ubukana buri hejuru y'igitambaro cya titaniyumu nitride, kandi ubushobozi bwo kwangirika buri hejuru. Ugereranyije n'igitambaro cya titaniyumu nitride, igikoresho cya titaniyumu carbonitride gishobora gutunganywa ku muvuduko wo kugaburira no gukata (40% na 60% hejuru y'igitambaro cya titaniyumu nitride, uko bikurikirana), kandi igipimo cyo gukuraho ibikoresho by'akazi kiri hejuru. Ibikoresho bya titaniyumu carbonitride bishobora gutunganya ibikoresho bitandukanye by'akazi.
Igishishwa cya titaniyumu aluminide ni ibara ry'umukara cyangwa imvi. Gitwikiriwe cyane cyane ku buso bw'igikoresho cya karubide gikozwe muri sima. Gishobora gutunganywa iyo ubushyuhe bwo gukata bugeze kuri 800 ℃. Kirakwiriye gukatwa byumye vuba. Mu gihe cyo gukata byumye, uduce duto two mu gace gakata dushobora gukurwaho n'umwuka ufunze. Titanium aluminide ikwiriye gutunganya ibikoresho byoroshye nko mu cyuma gikomeye, aloi ya titaniyumu, aloi ishingiye kuri nikeli, icyuma gikozwe muri steel n'aloi ya aluminium ifite silicon nyinshi.
Gusiga irangi ku gikoresho cyo gukata karubide gikozwe muri sima:
Iterambere ry'ikoranabuhanga ryo gusiga ibikoresho rigaragarira mu buryo bwo gukoresha nano-coating. Gusiga ibikoresho amagana bifite ubugari bwa nanometero nyinshi ku gikoresho cy'ibanze byitwa nano-coating. Ingano ya buri gace k'ibikoresho byo gusiga ni nto cyane, bityo umupaka w'ingano ni muremure cyane, ufite ubukana bwinshi bw'ubushyuhe. , Ingufu n'ubukomere bwo kuvunika.
Ubukana bwa Vickers bwo gutwikira ibintu bushobora kugera kuri HV2800 ～3000, kandi ubushobozi bwo kwangirika burushaho kwiyongeraho 5% ～50% ugereranyije n’ubw’ibikoresho bya micron. Nk’uko raporo zibivuga, ubu, ibikoresho 62 byo gutwikira bifite irangi risimburana rya titanium carbide na titanium carbonitride hamwe n’ibikoresho 400 bya TiAlN-TiAlN/Al2O3 nano-coated byamaze gukorwa.
Ugereranije n'ibisigazwa bikomeye byavuzwe haruguru, sulfide (MoS2, WS2) itwikiriwe ku cyuma cyihuta cyane yitwa soft coating, ikoreshwa cyane cyane mu gukata aloyide zikomeye za aluminiyumu, aloyide za titaniyumu n'ibindi byuma bidasanzwe.
Niba hari icyo ukeneye, nyamuneka hamagara MSK, dufite gahunda yo gutanga ibikoresho bisanzwe mu gihe gito kandi byihariye ku bakiriya.
