Spherical Cast Tungsten Carbide Powder

1. O le a le Spherical Cast Tungsten Carbide Powder?

Spherical lafo tungsten carbide pauta e aofia ai vaega efuefu pogisa, lea e faia e ultra maualuga-vevela spheroidization po o kasa atomization faagasologa.

Dendritic fausaga tioata e aofia ai le WC ma le W2C: maualuga liusuavai (2525 ℃), maualuga maaa (HV0.1≥2700), fausaga fulu maualuga (anotusi≥90%), mautu kemikolo, lelei le tafe, microhardness maualuga, ma le ofuina maualuga tetee. .

O lenei oloa o lo'o fa'aogaina mo mea fa'apipi'i mata'i suau'u taimane, plasma (PTA) mea fa'apipi'i, mea fa'apipi'i fa'apipi'i, ma fa'a'ele'ele fa'a'ele'ele (uaea).

2. E faapefea ona gaosia?

O le spherical tungsten carbide paʻu e masani lava ona faia mai le faʻaogaina masani tungsten carbide mana poʻo le faʻafefiloi o tungsten (W), tungsten carbide (WC), ma carbon (C). E lua faiga fa'atupu: (1) o le fa'afefiloi o le pauta tungsten fa'afefiloi ma le tungsten carbide ma le pa'u carbon e fa'afefeteina muamua. O le paluga liusua e fa'atomized e ala i le rotation atomizing po'o le ultra-maualuga-maualuga liusuavai & atomizing faagasologa. E spheroids i spherical WC particles i le faagasologa vave o le solidification ona o le vevesi i luga. (2) O le isi faiga e faʻavae i luga o le faʻaleleia o le faʻaaogaina masani o le paʻu tungsten carbide. O le fa'apalapala o le plasma, fa'auluina o le eletise, po'o le fa'afefeteina o le ogaumu fa'afefe eletise e fa'aaogaina i le faagasologa o le spheroidization e maua ai ni vaega WC spherical lelei.

3. Ae faapefea lona faatinoga faaletino?

E mafai ona pulea le aofa'i o kaponi;

Tulaga tutusa W2C ma WC fausaga lua-vaega;

Microhardness maualuga (HV0.1≥2700);

maualuga mama (≥99.9%);

maualalo le okesene (≤100ppm);

Sphericity maualuga (≥98 %);

Laulelei;

Leai ni polo satelite;

Fa'asoa le lapopo'a o fasimea;

Fa'ato'aga lelei (≤6.0s/50g);

Tulaga maualuga maualuga (≥9.5g/cm3);

O'o'o tele (≥10.5g/cm3).

O le pa'u tungsten carbide spherical e iai le microstructure o dendrites tutusa lelei, e pei ona faʻaalia i luga o le ata. O le ata SEM o loʻo i lalo o loʻo faʻaalia manino ai lona faʻaogaina o vaega WC spherical mafiafia tutusa. O lo'o fa'atumauina mea tau kemikolo mautu, fetuutuuna'i lelei ma le ma'a'a, ma le mata'ina o le ofuina/abrasion tete'e. Ole lapopo'a o le pa'u WC spherical spherical e mai le 0.025 mm i le 0.25 mm, o lo'o fa'aalia ai le iila efuefu pogisa. O lona density faapitoa o 15.8 ~ 16.7 g / cm3 ma micro-malosi e amata mai le 2700 ~ 3300 kg / mm2.

4. O ā ona faatatauga?

O le pa'u pa'u tungsten carbide spherical e fa'aaogaina lautele mo le fa'agata o vili vili ma meafaigaluega vili PDC, HVOF po'o le PTA fa'amama vevela i luga o luga o nofoa valve po'o totonu, ma fa'apipi'i fa'alava i luga o le flange o lo'o feagai ma vaega, ma isi.

Afai e te fiafia i oloa tungsten carbide ma e te manaʻo i nisi faʻamatalaga ma faʻamatalaga, e mafai ona e faʻafesoʻotaʻi i matou i le telefoni poʻo le meli i le agavale, pe SEND US MIL i le pito i lalo o le itulau.
