Spherical Cast Tungsten Carbide Powder

1. Chii chinonzi Spherical Cast Tungsten Carbide Powder?

Spherical cast tungsten carbide poda ine rima grey zvimedu, izvo zvinogadzirwa neakanyanya kutonhora spheroidization kana gasi atomization maitiro.

Dendritic crystal chimiro chinoumbwa neWC neW2C: yakakwira kunyungudika (2525 ℃), kuomarara kwakanyanya (HV0.1≥2700), chimiro cheminhenga yakakwira (zvirimo≥90%), kugadzikana kwemakemikari, kuyerera kwakanyanya, kuomarara kwepamusoro, uye kusapfeka kwakanyanya. .

Ichi chigadzirwa chinoshandiswa kugadzira madhaimondi oiri drill bit matrix zvinhu, plasma (PTA) pamusoro pezvinhu, zvekupfapfaidza welding zvinhu, uye simende carbide kupfeka-resistant electrodes (waya).

2. Kuchibudisa sei?

Iyo spherical tungsten carbide poda inowanzogadzirwa kubva yakajairwa cast tungsten carbide simba kana musanganiswa we tungsten (W), tungsten carbide (WC), uye kabhoni (C). Pane maitiro maviri ekugadzira: (1) musanganiswa we tungsten poda yakasanganiswa ne tungsten carbide uye kabhoni poda inonyungudutswa kutanga. Musanganiswa wakanyungudutswa wobva waitwa atomu nekutenderera atomizing kana Ultra-yepamusoro-tembiricha kunyungudika & atomizing maitiro. Iyo spheroids kuita spherical WC zvimedu panguva yekukurumidza kusimba maitiro nekuda kwekunetsana kwepasi. (2) Imwe nzira yakavakirwa pakushandurwa kweyakajairwa tungsten carbide poda. Kupfapfaidza kwePlasma, induction yemagetsi, kana kunyungudutswa kwechoto chemagetsi kunoiswa panguva ye spheroidization process kuti uwane yakanaka spherical WC zvimedu.

3. Zvakadini nekuita kwayo kwemuviri?

Inodzoreka yakazara kabhoni yemukati;

Uniform W2C uye WC maviri-chikamu chimiro;

High microhardness (HV0.1≥2700);

Kuchena kwepamusoro (≥99.9%);

Okisijeni yakaderera (≤100ppm);

High sphericity (≥98%);

Smooth surface;

Hapana mabhora esatellite;

Uniform particle size distribution;

Yakanakisa kuyerera zvivakwa (≤6.0s/50g);

Kuwanda kwehuwandu (≥9.5g/cm3);

Tap density (≥10.5g/cm3).

Iyo yakakandwa spherical tungsten carbide poda ine microstructure yeakanaka equiaxed dendrites, sezvakaratidzwa mumufananidzo uri pamusoro. Iyo SEM foto pazasi inoratidza zvakajeka morphology yayo ye dense homogeneous spherical WC zvimedu. Iyo inochengetedza yakagadzikana makemikari zvimiro, yakanaka kuchinjika uye kuoma, uye yakasarudzika kupfeka / abrasion kuramba. Iwo masaizi epadiki eakakandirwa spherical WC poda anobva pa0.025 mm kusvika 0.25 mm, anoratidza rima grey kupenya. Yayo chaiyo density ndeye 15.8 ~ 16.7 g/cm3 ine micro-kuomarara kubva 2700 ~ 3300 kg/mm2.

4. Ndeapi mashandisirwo ayo?

Iyo yakakandwa spherical tungsten carbide poda inoshandiswa zvakanyanya kuomarara mabhiti ekuchera uye PDC maturusi ekudhirowa, HVOF kana PTA yekupisa yekupisa pamusoro pezvigaro zvevharuvhu kana ndima dzemukati, uye weld yakafukidzira pane flange yakatarisana nenzvimbo, nezvimwe.

Kana iwe uchifarira tungsten carbide zvigadzirwa uye uchida rumwe ruzivo uye ruzivo, unogona KUBATA NESU nerunhare kana tsamba kuruboshwe, kana kuti TUMUMA MAIL pazasi peji.
