Spherical Cast Tungsten Carbide ntụ ntụ

1. Kedu ihe bụ Spherical Cast Tungsten Carbide Powder?

Spherical nkedo tungsten carbide ntụ ntụ nwere akụkụ isi awọ gbara ọchịchịrị, nke a na-eme site na spheroidization oke okpomọkụ ma ọ bụ usoro atomization gas.

Ọdịdị kristal dendritic nke nwere WC na W2C: ebe mgbaze dị elu (2525 ℃), ike siri ike (HV0.1≥2700), nhazi nku dị elu (ọdịnaya≥90%), nkwụsi ike nke kemịkalụ, ọmarịcha mmiri, nnukwu microhardness, na nnukwu mkpuchi mkpuchi mkpuchi. .

A na-eji ngwaahịa a eme ihe maka ihe ndị na-agbapụta mmanụ diamọnd, ihe ndị dị n'elu plasma (PTA), ihe ịgbado ọkụ, na cemented carbide wear-resistant electrodes (waya).

2. Kedu ka esi emepụta ya?

A na-emekarị tungsten carbide ntụ ntụ dị iche iche site na nkedo tungsten carbide ike ma ọ bụ ngwakọta nke tungsten (W), tungsten carbide (WC), na carbon (C). Enwere usoro mmepụta ihe abụọ bụ isi: (1) ngwakọta nke tungsten ntụ ntụ jikọtara ya na tungsten carbide na carbon ntụ ntụ na-agbaze na mbụ. A na-emezi ngwakọta a wụrụ awụ atom site na ngbanwe atomizing ma ọ bụ usoro mgbaze na oke okpomọkụ. Ọ na-agbaba n'ime spherical WC ahụ n'oge usoro siri ike ngwa ngwa n'ihi esemokwu elu. (2) Usoro ọzọ dabere na ngbanwe nke ntụ ntụ tungsten carbide mgbe niile. A na-etinye ịgbasa Plasma, ntinye ọkụ, ma ọ bụ ọkụ ọkụ na-eguzogide ọkụ n'oge usoro spheroidization iji nweta irighiri WC dị okirikiri.

3. Kedu maka arụmọrụ anụ ahụ ya?

mkpokọta carbon nwere ike ịchịkwa;

Uwe W2C na WC usoro nke abụọ;

Microhardness dị elu (HV0.1≥2700);

Ịdị ọcha dị elu (≥99.9%);

Obere oxygen (≤100ppm);

Ọdịiche dị elu (≥98%);

Elu dị nro;

Enweghị bọọlụ satịlaịtị;

Uniform urughuru nha nkesa;

Ngwongwo mmiri dị mma (≤6.0s / 50g);

Nnukwu njupụta dị elu (≥9.5g/cm3);

Njupụta mgbata (≥10.5g/cm3).

Ihe nkedo spherical tungsten carbide ntụ ntụ nwere microstructure nke ezigbo dendrites equiaxed, dị ka egosiri na foto dị n'elu. Foto SEM dị n'okpuru na-egosi n'ụzọ doro anya ọdịdị ọdịdị ya nke ụmụ irighiri ihe okirikiri WC dị okirikiri. Ọ na-edobe akụrụngwa kemịkalụ kwụsiri ike, ezigbo mgbanwe na ike siri ike, yana nguzogide iyi/abrasion pụtara ìhè. Nha urughuru nke nkedo WC ntụ ntụ sitere na 0.025 mm ruo 0.25 mm, nke na-egosipụta ncha isi awọ gbara ọchịchịrị. Njupụta ya kpọmkwem bụ 15.8 ~ 16.7 g / cm3 na micro-ike siri ike sitere na 2700 ~ 3300 kg / mm2.

4. Gịnị bụ ngwa ya?

A na-etinye ihe nkedo spherical tungsten carbide ntụ ntụ n'ọtụtụ ebe maka hardfacing nke mkpọpu bits na PDC drill ngwaọrụ, HVOF ma ọ bụ PTA thermal ịgba n'elu elu nke valvụ oche ma ọ bụ n'ime akụkụ, na weld machie na flange chere ihu ebe, wdg.

Ọ bụrụ na ị nwere mmasị na ngwaahịa tungsten carbide ma chọọ ozi ndị ọzọ na nkọwa, ị nwere ike ịkpọtụrụ anyị site na ekwentị ma ọ bụ mail n'aka ekpe, ma ọ bụ zipu ozi US na ala nke ibe.
