Spherical Cast Tungsten Carbide Foda

1. Menene Spherical Cast Tungsten Carbide Foda?

Simintin simintin gyare-gyaren tungsten carbide foda ya ƙunshi barbashi masu launin toka masu duhu, waɗanda aka yi ta hanyar spheroidization mai tsananin zafi ko tsarin atomization gas.

Dendritic crystal tsarin hada da WC da W2C: high narkewa batu (2525 ℃), high taurin (HV0.1≥2700), high gashin tsuntsu tsarin (abun ciki≥90%), chemically barga, m flowability, high microhardness, da kuma high lalacewa juriya. .

Ana amfani da wannan samfurin don kayan aikin haƙon mai na lu'u-lu'u, kayan saman plasma (PTA), kayan walda, da siminti mai jurewa lalacewa (waya).

2. Yadda za a samar da shi?

The spherical tungsten carbide foda ne gabaɗaya daga simintin tungsten carbide ikon na yau da kullun ko cakuda tungsten (W), tungsten carbide (WC), da carbon (C). Akwai da farko matakai biyu samar: (1) cakuda tungsten foda blended da tungsten carbide da carbon foda an narke farko. Narkar da narkakkar narke sannan kuma ana sarrafa ta ta hanyar jujjuyawa atomizing ko narkar da yanayin zafi mai tsananin zafi da tsari. Yana spheroids cikin sassa na WC mai siffar zobe yayin saurin ƙarfafa tsarin saboda tashin hankali. (2) Wani tsari ya dogara ne akan gyare-gyare na yau da kullum tungsten carbide foda. Ana amfani da feshin filasta, shigar da wutar lantarki, ko narkewar tanderun juriya ta wutar lantarki yayin aikin spheroidization don samun ɓarke ​​​​spherical WC.

3. Yaya game da aikinsa na zahiri?

Abubuwan da ake iya sarrafawa gabaɗaya;

Uniform W2C da WC tsari biyu;

Babban microhardness (HV0.1≥2700);

Babban tsabta (≥99.9%);

Ƙananan oxygen (≤100ppm);

Ƙarfin yanayi (≥98%);

M surface;

Babu kwallayen tauraron dan adam;

Rarraba girman barbashi na Uniform;

Kyakkyawan kaddarorin kwarara (≤6.0s/50g);

Babban girma (≥9.5g/cm3);

Matsa yawa (≥10.5g/cm3).

Simintin simintin simintin tungsten carbide foda yana da microstructure na dendrites masu daidaitawa, kamar yadda aka nuna a hoton da ke sama. Hoton SEM da ke ƙasa yana nuna a fili a fili yanayin halittarsa ​​na ɓangarorin WC masu kama da juna. Yana kiyaye kaddarorin sinadarai masu tsayayye, sassauci mai kyau da taurin kai, da kuma juriya na lalacewa/share. Girman ɓangarorin simintin simintin WC foda daga 0.025 mm zuwa 0.25 mm, wanda ke nuna haske mai launin toka mai duhu. Its takamaiman yawa ne 15.8 ~ 16.7 g / cm3 tare da micro-hardness jere daga 2700 ~ 3300 kg / mm2.

4. Menene aikace-aikacen sa?

Ana amfani da simintin simintin simintin simintin tungsten carbide foda don hardfacing na hakowa da kayan aikin hakowa na PDC, HVOF ko PTA thermal spray a saman wuraren kujerun bawul ko sassan ciki, da rufin walda a kan flange da ke fuskantar wuraren, da sauransu.

Idan kuna sha'awar samfuran carbide tungsten kuma kuna son ƙarin bayani da cikakkun bayanai, zaku iya tuntuɓar mu ta waya ko wasiƙa a hagu, ko Aika wasiƙun Amurka a kasan shafin.
