Izakhiwo Zemishini Nezomzimba ze-Tungsten Carbide

I-Tungsten carbide iyingxubevange enesakhi esiyinhloko sezimpushana ezihlanganisa i-tungsten carbide, i-titanium carbide, nempushana yensimbi efana ne-cobalt, i-nickel, njll, njengento enamathelayo, etholakala ngendlela ye-powder metallurgical. Isetshenziswa kakhulu ukwenza amathuluzi okusika anesivinini esikhulu kanye namaphethelo okusika aqinile, aqinile, kanye nezingxenye ezigqokwa kakhulu ukuze kwenziwe amakhaza afayo, namathuluzi okulinganisa.

Izakhiwo zemishini nezomzimba ze-tungsten carbide

1. Ukuqina okuphezulu nokumelana nokugqoka

Ngokuvamile, phakathi kwe-HRA86 ~ 93, kuncipha ngokunyuka kwe-cobalt. Ukumelana nokugqoka kwe-tungsten carbide kuyisici sayo esibaluleke kakhulu. Ekusetshenzisweni okungokoqobo, ama-carbides ubude izikhathi ezingu-20-100 kunamanye ama-alloys ensimbi angagugi.

2. Amandla aphezulu okulwa nokugoba.

I-sintered carbide ine-modulus enwebekayo ephezulu futhi ukugoba okuncane kakhulu kutholakala lapho ingaphansi kwamandla okugoba. Amandla okugoba ekushiseni okuvamile aphakathi kuka-90 no-150 MPa futhi ukuphakama kwe-cobalt, ayanda amandla okulwa nokugoba.

3. Ukumelana nokugqwala

Imvamisa isetshenziswa ezindaweni eziningi zamakhemikhali nezonakalisayo ngoba ama-carbides ngokuvamile awasebenzi ngamakhemikhali. Izakhiwo zamakhemikhali ezizinzile. Izinto ze-Carbide zinokumelana ne-asidi, ukumelana ne-alkali, ngisho ne-oxidation ebalulekile ngisho namazinga okushisa aphezulu.

4. Amandla e-torsional

Inani le-torsion liphindwe kabili kunelensimbi enesivinini esikhulu kanye ne-carbide yinto ekhethwayo yezinhlelo zokusebenza zokusebenza ngesivinini esikhulu.

5. Amandla acindezelayo

Amanye amabanga e-cobalt carbide ne-cobalt asebenza kahle kakhulu ngaphansi kwengcindezi ephezulu kakhulu futhi aphumelele kakhulu ekufakweni kwengcindezi efinyelela ku-7 million kPa.

6. Ukuqina

Amamaki e-carbide anosimende anokuqukethwe okuphezulu kwe-binder anokumelana nomthelela omuhle kakhulu.

7. Ukumelana nokushisa okuphansi kokugqoka

Ngisho nalapho izinga lokushisa liphansi kakhulu, i-carbide ihlala ikulungele ukugqoka ukumelana futhi inikeza ama-coefficients aphansi kakhulu ngaphandle kokusebenzisa i-lubricant.

8. Thermoharding

Izinga lokushisa elingu-500°C empeleni alishintshile futhi kusenokuqina okuphezulu ku-1000°C.

9. High conductivity ezishisayo.

I-carbide enosimende ine-thermal conductivity ephakeme kunaleyo nsimbi enesivinini esikhulu, ekhula ngokunyuka kwe-cobalt.

10. I-coefficient yokwandisa okushisayo incane ngokuqhathaniswa.

Iphansi kunensimbi enesivinini esikhulu, i-carbon steel, nethusi, futhi iyanda ngokunyuka kwe-cobalt.
