I-Spherical Cast Tungsten Carbide Powder

1. Iyini i-Spherical Cast Tungsten Carbide Powder?

I-spherical cast tungsten carbide powder iqukethe izinhlayiya ezimpunga ezimnyama, ezenziwe yi-ultra high-temperature spheroidization noma inqubo ye-atomization yegesi.

Isakhiwo sekristalu ye-Dendritic esakhiwa i-WC ne-W2C: indawo encibilikayo ephezulu (2525℃), ukuqina okuphezulu (HV0.1≥2700), ukwakheka kwezinsiba eziphakeme (okuqukethwe≥90%), ukuzinza kumakhemikhali, ukugeleza okuhle kakhulu, ubulukhuni obuncane obuphezulu, nokumelana nokugqokwa okuphezulu .

Lo mkhiqizo usetshenziselwa izinto zokwakha ze-diamond drill bit matrix, izinto ezingaphezulu ze-plasma (PTA), izinto zokushisela isifutho, kanye nama-electrode anosimende amelana ne-carbide (intambo).

2. Ikhiqizwa kanjani?

I-tungsten carbide powder eyindilinga ngokuvamile yenziwa ngamandla avamile we-tungsten carbide noma ingxube ye-tungsten (W), i-tungsten carbide (WC), ne-carbon (C). Ngokuyinhloko kunezinqubo ezimbili zokukhiqiza: (1) ingxube ye-tungsten powder ehlanganiswe ne-tungsten carbide kanye ne-carbon powder iyancibilika kuqala. Ingxube encibilikisiwe ibe i-athomu ngokuzungezisa i-atomizing noma i-ultra-high-temperature yokuncibilika nenqubo ye-atomizing. I-spheroids ibe yizinhlayiya ze-WC eziyindilinga phakathi nenqubo yokuqiniswa okusheshayo ngenxa yokushuba kwendawo. (2) Enye inqubo isekelwe ekuguqulweni kwe-tungsten carbide powder evamile. Ukufafaza kwe-Plasma, ukufakwa kukagesi, noma ukuncibilika kwesithando sokumelana nogesi kusetshenziswa ngesikhathi senqubo ye-spheroidization ukuthola izinhlayiya ezinhle eziyindilinga ze-WC.

3. Kuthiwani ngokusebenza kwayo ngokomzimba?

Ingqikithi yekhabhoni elawulekayo;

Isakhiwo esinezigaba ezimbili se-W2C kanye ne-WC;

I-microhardness ephezulu (HV0.1≥2700);

Ukuhlanzeka okuphezulu (≥99.9%);

I-oxygen ephansi (≤100ppm);

I-sphericity ephezulu (≥98 %);

Indawo ebushelelezi;

Awekho amabhola esathelayithi;

Ukusabalalisa usayizi wezinhlayiyana ezifanayo;

Izakhiwo ezinhle kakhulu zokugeleza (≤6.0s/50g);

Ukuminyana kwenqwaba (≥9.5g/cm3);

Ukuminyana kokuthepha (≥10.5g/cm3).

I-cast spherical tungsten carbide powder ine-microstructure yama-dendrites alinganayo, njengoba kuboniswe esithombeni esingenhla. Isithombe se-SEM esingezansi sibonisa ngokusobala i-morphology yayo yezinhlayiya eziminyene eziyindilinga ze-WC eziminyene. Igcina izakhiwo zamakhemikhali ezizinzile, ukuguquguquka okuhle nobulukhuni, nokumelana okuvelele kokugqoka/ukuhuzuka. Osayizi bezinhlayiyana be-cast spherical WC powder basuka ku-0.025 mm kuya ku-0.25 mm, okubonisa ukucwebezela okumpunga okumnyama. Ukuminyana kwayo okuqondile ngu-15.8~16.7 g/cm3 enobulukhuni obuncane obusuka ku-2700 ~ 3300 kg/mm2.

4. Yiziphi izicelo zayo?

I-cast spherical tungsten carbide powder isetshenziswa kabanzi ukuze kuqiniswe izingcezu zokubhola kanye namathuluzi okubhola e-PDC, i-HVOF noma i-PTA eshisayo yokufutha endaweni yezihlalo zamavalvu noma amaphaseji angaphakathi, kanye nokumbozwa kwe-weld ezindaweni ezibheke e-flange, njll.

Uma unentshisekelo emikhiqizweni ye-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma ngemeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi nekhasi.
