Mu myaka yashize, ibikoresho byo guca PCD byakoreshejwe cyane mu nganda zitunganya aluminium, amavuta ya aluminiyumu, umuringa, hamwe n’ibikoresho bitari ibyuma.
Ni izihe nyungu z'ibikoresho byo guca PCD mugutunganya aluminium nuburyo bwo guhitamo ibikoresho bikwiye byo gukata PCD?
NikiIbikoresho byo gukata PCD？
Ibikoresho byo gukata PCD mubisanzwe bivuga ibikoresho bya diyama polycrystalline.Urupapuro rwa PCD rwakoreshejwe rwashizwe munganda ya pome ya diyama isanzwe cyangwa ibihimbano (irimo ibyuma nka cobalt na nikel) muburyo runaka mubushyuhe bwinshi (1000-2000 ℃) hamwe numuvuduko mwinshi (ikirere 50000 kugeza 100000).Ntabwo ifite ubukana bwinshi no kwambara PCD gusa, ahubwo ifite imbaraga nubukomezi bwa karbide.
Nyuma yo gutunganyirizwa mubikoresho byo gukata, ifite ibiranga ubukana bwinshi, ubushyuhe bwinshi bwumuriro, coefficente yo kwagura ubushyuhe buke, modulus yo hejuru ya elastike, hamwe na coefficient de friction.
Ibikoresho byo guca OPT nibikoresho byujuje ubuziranenge PCD itanga, Turagutera inkunga yo kugura ibyo usabwa buri mwaka kubiciro byapiganwa, bitanga serivisi nziza kandi zitandukanye.
Ibyiza bya PCD shyiramo mugutunganya aluminium
(1) Ubukomezi bwibikoresho bya PCD burashobora kugera kuri 8000HV (inshuro 80-120 za karbide)
kandi imyambarire yabo yo kwambara nibyiza cyane.

(6) Ibikoresho bya PCD bifite modulus ihanitse kandi ntibishobora kuvunika.Iradiyo idahwitse yo gukata irashobora kuba hasi cyane, ishobora kugumana ubukana bwuruhande rwo gutema igihe kirekire.
Ukurikije ibyiza byavuzwe haruguru, ibikoresho bya PCD birashobora gutunganya ibikoresho bya aluminiyumu ivanze n'umuvuduko mwinshi cyane, hamwe nibikoresho byubuzima bwibihumbi byinshi kugeza ku bihumbi mirongo.Cyane cyane kibereye kubyara umusaruro mwinshi wihuta kandi mwinshi (3C digitale, inganda zitwara ibinyabiziga, ikibuga cyindege), nko gutunganya ibicuruzwa biva mububiko bwa digitale, piston yimodoka, ibiziga byimodoka, impeta yimodoka, nibindi.
Uburyo bwo guhitamo Ibikoresho byo gukata PCD?
Muri rusange, uko ingano ya PCD nini, niko imbaraga zo kwambara zikoreshwa.
Mubisanzwe, ibice byiza bya PCD bikoreshwa mugutunganya neza cyangwa ultra precision, mugihe ibikoresho bito bya PCD bikoreshwa mugukora nabi.
Abakora ibikoresho mubisanzwe barasaba gukoresha amanota meza ya PCD kugirango batunganyirize ibikoresho bya silikoni yubusa kandi ntoya ya aluminium ya aluminiyumu, kandi bagakoresha amanota ya PCD yo mu rwego rwo gutunganya ibikoresho bya aluminiyumu ya aluminiyumu, kubwimpamvu imwe.
Ubwiza bwubuso butunganywa nibikoresho bya PCD ntibiterwa gusa nubunini bwibikoresho, ahubwo binaterwa nubwiza bwibikoresho, bityo ubwiza bwibikoresho bya PCD bugomba kuba bwiza.
Muri rusange hari uburyo bubiri busanzwe bwo gutunganya ibikoresho bya PCD, imwe ikanyura mugukata insinga.Ubu buryo bufite amafaranga make yo gutunganya, ariko ubwiza bwimpande ni impuzandengo.Ubundi buryo bugerwaho hifashishijwe gutunganya lazeri, ifite igiciro cyinshi ho gato, ariko ubwiza bwuruhande rwo gukata buri hejuru cyane (hariho nuburyo bwo kubanza gutunganya lazeri ikarishye hanyuma ugasya imashini itomoye, ifite ireme ryiza ryo gukata inkombe).Biracyakenewe kwitondera cyane muguhitamo.
Mu magambo make, ibyo aribyo byose.Ibindi bisobanuro byihariye, harimo ibiciro no kugabanya ibipimo, nabyo bigomba kwerekeza kubicuruzwa byihariye bitangwa nababikora batandukanye.Byongeye kandi, usibye guhitamo gushyira mu gaciro ibikoresho bya geometrie no kugabanya ibipimo, gutunganya aluminiyumu rimwe na rimwe bisaba abatanga ibikoresho gutanga ibisubizo kubibazo byahuye nabyo mugihe cyo gukoresha ibikoresho.
