Ngwino wige ibya hss
Ibyuma Byihuta (HSS) nigikoresho cyijimye hamwe no gukomera kwinshi, kwambara cyane no kurwanya ubushyuhe bwinshi, bizwi kandi ko bikatirwa nubwo bikonje kandi birakaze. Yitwa kandi icyuma cyera.
Icyuma cyihuta ni alloy ibyuma bigoye birimo ibintu bifatika bya carbide nka tungsten, Molybdenum, Molybdenum, Chromium, Vadium na Coalt. Umubare wuzuye wibintu bigera kuri 10 kugeza 25%. Irashobora gukomeza gukomera kwinshi (hafi 500 ℃) mugukata byihuta, HRC irashobora kuba hejuru ya 60. Nibintu byingenzi biranga hss - gukomera gutukura. Kandi ibikoresho bya karubone mu kuzimya ubushyuhe buke, ubushyuhe buke, nubwo hari ubushyuhe bukabije, ariko igihe ubushyuhe buzagabanuka cyane hamwe nubushobozi bwo guca ibyuma, bigabanya ibikoresho bya karubone. Kandi yihuta-yihuta kubera ubushyuhe bwiza butukura, kugirango uhimbane amakosa yica ibikoresho bya karubone.
Ibyuma byihuta bikoreshwa cyane mugukora ibikoresho byicyuma cyoroheje kandi bitera ingaruka, ariko nanone haple clure ndende irapfa, nko guhindura ibikoresho, imyitozo, imashini isaba gupfa.
Ngwino wige ibyuma bituruka
Icyuma cya Tungsten (Carbide) gifite urukurikirane rw'ibintu byiza nko gukomera kwinshi, kwambara imbaraga, imbaraga zo kurwanya ubushyuhe no kwambara ubushyuhe no ku bushyuhe bwa 5000 ℃.
Icyuma cya Tungsten, ibice byingenzi bidurukirana na carbide na codalt, kuri 99% byibice byose, bityo bizwi kandi nka CORTBen, kandi bizwi nabyo kuba amenyo yinganda zigezweho.
Icyuma cya Tungsten nikintu cyananiranye kirimo byibuze ibigize icyuma. Tungsten Carbide, Calbide ya Coballat, Niobium Carbide, Titanium Carbide, na tantalum carbide nibice bikunze kugaragara byibyuma biturika. Ingano y'ibinyampeke y'ikinyampeke (cyangwa icyiciro) isanzwe iri hagati ya 0.2-10, hamwe n'ibinyampeke bya karbide bihujwe ukoresheje icyuma gihuza. Ibyuma bihuje muri rusange ni ibyuma by'icyuma, mubisanzwe coballat na nikel. Rero hanangsten-cobalt alloys-codalt alloys, tungsten-nikel alloys na tungsten-titanium-cobalt alloys.
Kwirukana SINTERN gushiraho ni ugukanda ifu muri kaleti, hanyuma mu itanura ryibintu kugirango ubushyure ubushyuhe runaka (ubushyuhe bwimiterere), hanyuma uyikosore kugirango ubone ibikoresho byicyuma bisabwa.
①tungsten na Coballat barangije karbide
Ibigize ibyingenzi biraturika karbide (WC) na Binder Coballat (CO). Urwego rugizwe na "YG" ("Hard, Cobalt" muri Hanu Pinyin) n'ijanisha ryimpuzandengo ya cobalt. Kurugero, yg8, bivuze impuzandengo ya WCO = 8% naho ikiruhuko cyaduhangayikishije karbide yashimangiye karbide.
②tungsten, Titanium na Coballat barangije Carbide
Ibice byingenzi biringuye karbide, karbiyo karbiyo (Tic) na coabant. Urwego rugizwe na "yt" ("Hard, Titanium" muri Hanu Pinyin) hamwe nibisanzwe bya Titanium Carbide. Kurugero, yt15, bisobanura impuzandengo ya Tic = 15%, ikiruhuko cyidumurwa karbide na coabal ikubiyemo titanium titanium titanium carbide.
③tungsten-Titanium-Tantalum (Niobium) Carbide
Ibice by'ingenzi birigurika kwarika, Titonium Carbide, Tantalum Carbide (cyangwa niobium karbide) na collat. Ubu bwoko bwa carbide nabwo bwitwa rusange-intego cyangwa karbide rusange. Urwego rugizwe na "YW" ("Hard" na "Miliyoni" muri Hanu Pinyun) wongeyeho umubare ukurikiranye, nka YW1.
Icyuma cya Tungsten gifite urukurikirane rw'ibintu byiza nko gukomera kwinshi, kwambara kurwanya, imbaraga nziza n'uburambo, kandi ubushyuhe bwinshi, kandi biracyafite ubushyuhe bwo hejuru kuri 1000 ℃. Imyizerere ya CARBide ikoreshwa cyane nkibikoresho, nko guhindura ibikoresho, ibikoresho byo gusya, imyitozo yarambiranye, nibindi. Umuvuduko ukabije wa Carbide Nshya uhwanye inshuro magana
