Mechanical uye Zvenyama Zvivakwa zveTungsten Carbide

Tungsten carbide ialloy ine chinhu chikuru chehupfu zvinosanganisira tungsten carbide, titanium carbide, uye simbi poda senge cobalt, nickel, nezvimwe, seanonamira, inowanikwa kuburikidza nehupfu metallurgical nzira. Inonyanya kushandiswa kugadzira maturusi ekucheka-yepamusoro-soro uye yakaoma, yakaoma, yakaoma-yekucheka mipendero, uye yakakwirira-kupfeka zvikamu zvekugadzira inotonhora inofa, uye yekuyera maturusi.

Mechanical uye zvemuviri zvimiro zve tungsten carbide

1. High kuoma uye kupfeka kuramba

Kazhinji, pakati peHRA86 ~ 93, inoderera nekuwedzera kwecobalt. Kupfeka kuramba kwe tungsten carbide ndiyo inonyanya kukosha. Mumashandisirwo anoshanda, macarbides akareba zvakapetwa ka20-100 pane mamwe masimbi asingapfeki.

2. High anti-bending simba.

Iyo sintered carbide ine yakakwira elastic modulus uye iyo diki bend inowanikwa kana ichiiswa pasi pesimba rekukotama. Simba rekukotama patembiricha yakajairika iri pakati pe90 ne150 MPa uye iyo yakakwira cobalt, inokwira iyo anti-kupeta simba.

3. Corrosion resistance

Inowanzoshandiswa munzvimbo dzakawanda dzemakemikari uye dzinoparadza nokuti carbides inowanzoita makemikari inert. Zvimwe zvakagadzikana zvemakemikari zvinhu. Carbide zvinhu zvine acid-resistant, alkali-resistant, uye kunyange yakakosha oxidation kunyangwe pakupisa kwakanyanya.

4. Torsional simba

Huwandu hwe torsion hwakapetwa kaviri hwesimbi inomhanya uye carbide ndiyo inosarudzirwa zvinhu zvekumhanya-mhanya maapplication.

5. Kudzvinyirira simba

Mamwe magiredhi ecobalt carbide necobalt ane mashandiro akakwana ari pasi pe-ultra-high pressure uye anobudirira zvikuru mukumanikidza kushandiswa kweanosvika mamirioni manomwe kPa.

6. Kuoma

Cemented carbide mamakisi ane yakakwira binder zvemukati ane yakanakisa kukanganisa kupikisa.

7. Kudzikira kwekushisa kupfeka kusagadzikana

Kunyangwe patembiricha yakaderera zvakanyanya, iyo carbide inoramba yakanaka kupfeka kuramba uye inopa yakaderera friction coefficients pasina kushandisa lubricant.

8. Thermoharding

Tembiricha ye500°C haina kushanduka uye kuchine kuoma kwakanyanya pa1000°C.

9. High thermal conductivity.

Cemented carbide ine yakanyanya kupisa conductivity kupfuura iyo yakakwirira-kumhanya simbi, iyo inowedzera nekuwedzera kwecobalt.

10. Iyo coefficient yekuwedzera kwekushisa ishoma.

Iyo yakaderera pane yakakwirira-kumhanya simbi, kabhoni simbi, uye mhangura, uye inowedzera nekuwedzera kwekobalt.
