Amavuta akomeye ni umusemburo ugizwe ahanini na karbide imwe cyangwa nyinshi zinanirwa (nka karubide ya tungsten, karubide ya titanium, nibindi) muburyo bwifu, hamwe nifu yicyuma (nka cobalt, nikel) ikora nka binder.Yakozwe binyuze muri powder metallurgie.Amavuta akomeye akoreshwa cyane mugukora ibikoresho byihuta byo gukata nibikoresho byo gukata kubikoresho bikomeye kandi bikomeye.Ikoreshwa kandi mukubyara imbeho ikora ikonje, gupima neza, hamwe nibikoresho birwanya kwambara cyane birwanya ingaruka no kunyeganyega.
Ibiranga imbaraga zikomeye
(1)Gukomera cyane, kwambara birwanya, no gukomera gutukura.
Amavuta akomeye yerekana ubukana bwa 86-93 HRA ku bushyuhe bwicyumba, bingana na 69-81 HRC.Ikomeza ubukana bwinshi ku bushyuhe bwa 900-1000 ° C kandi ifite imbaraga zo kwihanganira kwambara.Ugereranije nicyuma cyihuta cyibikoresho byuma, alloy alloy ituma guca umuvuduko wikubye inshuro 4-7 kandi ufite igihe cyo kubaho inshuro 5-80.Irashobora guca mubikoresho bikomeye hamwe nuburemere bugera kuri 50HRC.
(2)Imbaraga nyinshi hamwe na moderi yo hejuru ya elastike.
Amashanyarazi akomeye afite imbaraga zo gukomeretsa zingana na MPa 6000 hamwe na moderi ya elastike iri hagati ya (4-7) × 10 ^ 5 MPa, byombi biruta ibyuma byihuta.Nyamara, imbaraga zayo zihindagurika ni nkeya, mubisanzwe kuva kuri 1000-3000 MPa.
(3)Kurwanya ruswa nziza no kurwanya okiside.
Amavuta akomeye muri rusange agaragaza ko arwanya ruswa yo mu kirere, acide, alkalis, kandi ntabwo ikunda okiside.
(4)Coefficient yo kwaguka kumurongo.
Gukomera cyane bigumana imiterere nubunini bihamye mugihe gikora bitewe na coefficient nkeya yo kwagura umurongo.
(5)Ibicuruzwa byakozwe ntibisaba gutunganya cyangwa kongera gukora.
Bitewe n'ubukomere bwayo bwinshi n'ubukonje, ibivanze bikomeye ntibishobora gukomeza gukata cyangwa gusubira inyuma nyuma yo gukora ifu ya metallurgie ikora no gucumura.Niba hakenewe ubundi buryo bwo gutunganya, uburyo nko gutunganya amashanyarazi, gukata insinga, gusya amashanyarazi, cyangwa gusya kabuhariwe hamwe no gusya inziga.Mubisanzwe, ibikomangoma bikomeye bivanze mubipimo byihariye birasobekeranye, bihujwe, cyangwa bifatanyirijwe kumubiri kubikoresho cyangwa ibishingwe kugirango bikoreshwe.
Ubwoko busanzwe bwa Alloy
Ubwoko busanzwe bukomeye buvangwa mubyiciro bitatu bishingiye kubigize no kuranga imikorere: tungsten-cobalt, tungsten-titanium-cobalt, na tungsten-titanium-tantalum (niobium).Ikoreshwa cyane mubikorwa ni tungsten-cobalt na tungsten-titanium-cobalt ikomeye.
(1)Tungsten-Cobalt Ikomeye:
Ibice byibanze ni tungsten karbide (WC) na cobalt.Urwego rwerekanwa na code "YG", hagakurikiraho ijanisha ryibirimo cobalt.Kurugero, YG6 yerekana tungsten-cobalt ikomeye ivanze hamwe na 6% ya cobalt hamwe na 94% bya karubide ya tungsten.
(2)Tungsten-Titanium-Cobalt Ikomeye:
Ibice byibanze ni tungsten karbide (WC), titanium karbide (TiC), na cobalt.Urwego rwerekanwa na kode "YT", ikurikirwa nijanisha ryibintu bya titanium karbide.Kurugero, YT15 yerekana tungsten-titanium-cobalt ikomeye ivanze hamwe na 15% ya karbide ya titanium.
(3)Tungsten-Titanium-Tantalum (Niobium) Amavuta akomeye:
Ubu bwoko bukomeye buvanze kandi buzwi nkibisanzwe bigizwe na bose cyangwa ibintu byinshi bigoye.Ibyingenzi byingenzi ni tungsten karbide (WC), titanium karbide (TiC), tantalum carbide (TaC), cyangwa niobium karbide (NbC), na cobalt.Urwego rwerekanwa na kode "YW" (inyuguti ya "Ying" na "Wan," bisobanura bikomeye kandi rusange mu gishinwa), ikurikirwa numubare.
Of Porogaramu Zikomeye
(1)Gukata ibikoresho by'ibikoresho:
Amavuta akomeye akoreshwa cyane mugukora ibikoresho byo gukata ibikoresho, harimo ibikoresho byo guhindura, gusya, gusya, ibyuma, n'ibindi. , guta umuringa, hamwe nibiti.Tungsten-titanium-cobalt ikomeye ivanze ikwiranye no gutunganya chip ndende yo gukora ibyuma nibindi byuma bya fer.Mu mavuta, abafite ibinini bya cobalt birakwiriye gutunganywa bikabije, mugihe abafite cobalt yo hepfo bakwiriye kurangiza.Isi yose ivanze cyane ifite ibikoresho birebire byubuzima mugihe utunganya ibikoresho bigoye-gukata nkibyuma bitagira umwanda.
(2)Ibikoresho byabumbwe:
Gukomera cyane gukoreshwa nkibikoresho byo gushushanya ubukonje bipfa, kashe ikonje irapfa, gukuramo ubukonje bipfa, naho umutwe ukonje urapfa.
Gukomera gukomeye imitwe ikonje ipfa gukoreshwa kwambara cyangwa ingaruka zikomeye.Ibintu byingenzi bisabwa ni ingaruka nziza zikomeye, gukomera kuvunika, imbaraga zumunaniro, imbaraga zunama, hamwe no kwihanganira kwambara neza.Mubisanzwe, ibiciriritse kugeza hejuru ya cobalt hamwe nibiciriritse-binini-ibinyamisogwe byatoranijwe.Amanota asanzwe arimo YG15C.
Mubisanzwe, hariho ubucuruzi hagati yo kurwanya kwambara no gukomera mubikoresho bikomeye.Kunoza imyambarire yo kwambara bizavamo kugabanuka gukomera, mugihe kongera imbaraga byanze bikunze bigabanuka.
Niba ikirango cyatoranijwe cyoroshye kubyara hakiri kare no kwangirika mugukoresha, birakwiye guhitamo ikirango gifite ubukana buhanitse;Niba ikirango cyatoranijwe cyoroshye kubyara hakiri kare no kwangirika mugukoresha, birakwiye guhitamo ikirango gifite ubukana bwinshi kandi cyananiwe kwambara.Ibyiciro bikurikira: YG15C, YG18C, YG20C, YL60, YG22C, YG25C kuva ibumoso ugana iburyo, ubukana buragabanuka, kurwanya kwambara biragabanuka, ubukana buratera imbere;Ibinyuranye nibyo, ibinyuranye nukuri.
(3) Gupima ibikoresho nibice bidashobora kwambara
Carbide ya Tungsten ikoreshwa muburyo bwo kwangiza no kugabanya ibikoresho byo gupima, gufata neza imashini zisya, kuyobora no kuyobora utubari tw’imashini zisya zitagira hagati, hamwe n’ibice bidashobora kwangirika nka santere ya lathe.
