Likarolo le Tšebeliso ea Cemented Carbide

Likarolo tsa tungsten carbide

Tungsten carbide e na le boima bo phahameng le ho hanyetsa ho roala. Lebelo la ho itšeha ha lisebelisoa tsa carbide ke makhetlo a 4 ho isa ho a 7 ho feta a tšepe e lebelo le makhetlo a 5 ho isa ho a 80 bophelo bo phahameng ba ts'ebeletso. Lihlahisoa tsa Carbide li ka khaola lisebelisoa tse thata tse ka bang 50HRC. Lingoliloeng li tla hlahisa tsebo e itseng ea bohlokoa mabapi le carbide e entsoeng ka samente.

Lintho tse bonahalang tsa tungsten carbide

Carbide e entsoeng ka samente haholo-holo ke phofo e nyenyane ea carbides (WC, TiC) ea litšepe tse thata tse thata haholo. Likarolo tse ka sehloohong ke lihlahisoa tsa metallurgical tse kentsoeng ka seboping sa vacuum kapa sebōpi sa phokotso ea haedrojene e nang le cobalt (Co), nickel (Ni), le molybdenum (Mo) joalo ka setlamo.

Matrix ea carbide e entsoeng ka samente e entsoe ka likarolo tse peli: karolo e 'ngoe ke mohato o thata,' me karolo e 'ngoe ke tšepe e kopanyang.

Karolo e thata ke carbide, joalo ka tungsten carbide, titanium carbide, le tantalum carbide. Ho thatafala ha eona ho phahame haholo. Libaka tsa eona tse qhibilihang li ka holimo ho 2000 ° C, 'me tse ling li bile li feta 4000°C. Ho ba teng ha mokhahlelo o thata ho etsa qeto ea ho thatafala haholo le ho hanyetsa ha carbide.

Litlhoko tsa boholo ba lijo-thollo tsa Tungsten carbide WC bakeng sa carbide e entsoeng ka samente sebelisa boholo ba lijo-thollo WC ho latela lits'ebetso tse fapaneng.

Sengoliloeng sena haholo-holo se hlahisa litšebeliso tse tharo tsa carbide e entsoeng ka samente:

1. Tungsten carbide bakeng sa ho etsa lisebelisoa tsa ho itšeha carbide

Lisebelisoa tsa ho seha li-carbide li sebelisoa haholo bakeng sa ho itšeha le ho etsa machining. Lisebelisoa tse ntle tsa machining joalo ka li-blade tsa seha maotong le lithipa tsa V-CUT li sebelisa WC e hloekileng haholo, e nyane, le WC e hloekisitsoeng hantle. Li-alloys tse sebetsang ka thata li sebelisa WC ea lijo-thollo tse mahareng. Gravity cutting alloys le li-alloys tsa ho itšeha tse boima li sebelisa Granular WC e mahareng le e mahoashe joalo ka lisebelisoa tse tala.

2. Carbide e entsoeng ka samente bakeng sa ho etsa lisebelisoa tsa merafo ea carbide

Lejoe le na le boima bo phahameng le boima bo phahameng ba tšusumetso. Coarse WC e amoheloa, 'me tšusumetso ea lefika e nyane ka mojaro o monyane. WC e boholo bo mahareng e sebelisoa joalo ka thepa e tala.

3. Alloy e thata bakeng sa ho etsa likarolo tse sa sebetseng tsa carbide

Ha ho totobatsoa ho hanyetsa ha eona ho apara, ho hanyetsa khatello, le ho qeta holimo, WC e nang le boholo bo fapaneng e sebelisoa e le thepa e tala, 'me thepa e tala ea WC e mahareng le e mahoashe e sebelisoa e le thepa ea mantlha.

4. Tšepe e thata bakeng sa ho etsa tungsten carbide E shoa

The carbide die na le makhetlo a mashome a 'maloa a bophelo ba tšebeletso nako e telele ho feta hlobo ea tšepe. Mofuta oa carbide o na le boima bo phahameng, matla a phahameng, ho hanyetsa kutu, ho hanyetsa mocheso o phahameng, le coefficient e nyenyane ea ho atolosa, hangata e entsoeng ka tungsten cobalt.

Haeba u thahasella lihlahisoa tsa tungsten carbide 'me u batla boitsebiso bo eketsehileng le lintlha tse ling, u ka RE THUTA ka mohala kapa ka poso ka ho le letšehali, kapa U RE THUSE MAIL botlaaseng ba leqephe.
