Kedu ihe kpatara ngwaahịa Tungsten Carbide ji na-adalata mgbe emechara?

Tungsten carbide bụ otu n'ime ngwá ọrụ kachasị ewu ewu na ụlọ ọrụ ọgbara ọhụrụ. N'ime ụlọ ọrụ mmepụta ihe, anyị na-etinye metallurgy ntụ ntụ mgbe niile iji mepụta ngwaahịa tungsten carbide. Na sintering, ị nwere ike ịhụ na tungsten carbide ngwaahịa adalata. Yabụ kedu ihe mere ngwaahịa tungsten carbide, kedu ihe kpatara ngwaahịa tungsten carbide ji daa mgbe ọ gbasasịrị? N'isiokwu a, anyị ga-enyocha ihe kpatara ya.

Imepụta ngwaahịa tungsten carbide

1. Ịhọrọ na ịzụta 100% akụrụngwa, tungsten carbide;

2. Ịgwakọta tungsten carbide ntụ ntụ na cobalt ntụ ntụ;

3. Na-egweri ntụ ntụ agwakọta na igwe agwakọta bọọlụ na mmiri mmiri dị ka mmiri na ethanol;

4. fesa ihicha ntụ ntụ mmiri;

5. Compacting ntụ ntụ n'ime ụdị dị iche iche na nha dị ka ndị ahịa chọrọ. A na-ekpebi ụzọ ntinye kwesịrị ekwesị site na ụdị na nha nke ngwaahịa tungsten carbide;

6. Na-agbaji n'ọkụ ọkụ;

7. Nleba anya nke ikpeazụ.

Nkeji nke sintering tungsten carbide ngwaahịa

1. Mwepụ nke onye na-akpụzi ihe na ogbo tupu ọkụ;

N'oge a, onye ọrụ kwesịrị ịchịkwa okpomọkụ ka ọ na-abawanye nwayọọ nwayọọ. Ka okpomọkụ na-abawanye nke nta nke nta, mmiri, gas, na ihe mgbaze dị na tungsten carbide compacted ga-ekupụ, ya mere, usoro a bụ iwepụ ihe na-emepụta ihe na ihe ndị ọzọ fọdụrụnụ na ọkụ tupu ọkụ. Nke a ogbo mere n'okpuru 800 ℃

2. Ogbo sintering siri ike;

Ka okpomọkụ na-abawanye na karịa 800 ℃, ọ na-atụgharị na nke abụọ ogbo. Oge a na-eme tupu mmiri mmiri adị n'ime usoro a.N'oge a, plastik na-asọba na-abawanye, anụ ahụ na-agba agba na-ebelata nke ukwuu.Enwere ike ịhụ mbelata nke Tungsten carbide nke ọma, ọkachasị karịa 1150 ℃.

3. Mmiri-phase sintering ogbo;

N'ime oge nke atọ, okpomọkụ ga-abawanye ruo okpomọkụ na-ekpo ọkụ, okpomọkụ kachasị elu n'oge nkwụsị. A na-emecha mbelata ngwa ngwa mgbe usoro mmiri mmiri pụtara na tungsten carbide na porosity nke tungsten carbide na-ebelata.

4. Ogbo oyi.

Enwere ike wepu carbide cimented mgbe amịchara ya n'ọkụ na-ekpo ọkụ ma mee ka ọ dị jụụ n'ime ụlọ. Ụfọdụ ụlọ ọrụ ga-eji ikpo ọkụ na-ekpofu ọkụ n'ime ọkụ na-ekpo ọkụ maka ojiji ọkụ ọhụrụ. N'ebe a, ka okpomọkụ na-adaba, a na-emepụta microstructure ikpeazụ nke alloy.

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.
