Usoro anọ bụ isi nke ọgwụgwọ Tungsten Carbide okpomọkụ

Tungsten carbide nwere elu arụmọrụ na magburu onwe n'ibu na anụ ahụ Njirimara, gụnyere elu eyi-eguzogide, corrosion eguzogide, ekwe ike, torsion ike, wdg, ọtụtụ ebe eji egbutu ngwaọrụ, oyi ebu, eyi akụkụ, wdg. Isiokwu na-na nkenke ewebata anọ. isi nkebi nke tungsten carbide okpomọkụ ọgwụgwọ, nke nwere ike melite anụ ahụ na n'ibu Njirimara nke siri ike alloy.

Usoro ọgwụgwọ okpomọkụ nke tungsten carbide nwere ike kewaa ụzọ anọ bụ isi.

1. Mwepụ nke ịkpụzi ihe na tupu sintering

N'oge mmalite nke ịmegharị ahụ, onye na-emepụta ihe na-eji nwayọọ nwayọọ na-agbaze ma ọ bụ na-ekpochapụ, ewezuga ahụ ahụ a na-emegharị ahụ, n'otu oge ahụ, ndị na-emepụta ihe na-eme ka ọkpụkpụ ahụ na-eme ka ọkpụkpụ ahụ dị iche iche, na ọnụ ọgụgụ carbon ga-adịgasị iche dabere n'ụdị, ego, na usoro nke sintering. . A na-ebelata ntụ ntụ n'elu oxide, na hydrogen nwere ike ibelata cobalt na tungsten oxides na ikpo ọkụ na-ekpo ọkụ. Site na mmeghachi omume na-adịghị ike n'etiti carbon na oxygen, nrụgide kọntaktị dị n'etiti ntụ ntụ ntụ na-eji nwayọọ nwayọọ wepụ. The bonding metal ntụ ntụ na-amalite ịzaghachi na recrystallization na elu mgbasa na-amalite ime. Ike mgbochi abawanyela.

2. Ogbo nke siri ike-phase sintering (800°C - eutectic okpomọkụ)

Na ọnụnọ nke mmiri mmiri mmiri, na mgbakwunye na usoro nke na-aga n'ihu na ọkwa gara aga, mmeghachi omume siri ike na mgbasa ozi na-eme ka ọ dịkwuo elu site na mmụba nke mmiri plastik, na nkwụsị nke doro anya na-apụta n'ime ahụ siri ike.

3. Ogbo nke mmiri mmiri-phase sintering (eutectic okpomọkụ - sintering okpomọkụ)

Mgbe akụkụ mmiri mmiri nke anụ ahụ na-eme ihe na-eme, mkpakọ ahụ na-agwụ ngwa ngwa, mgbe ahụ, mgbanwe kristal na-eme. A na-emepụta usoro nhazi na nhazi nke carbide.

4. Ogbo oyi (sintering okpomọkụ - ụlọ okpomọkụ)

N'oge a, nhazi na nhazi nke tungsten carbide na-enwe mgbanwe ụfọdụ n'okpuru ọnọdụ dị jụụ dị iche iche, nke na-eme ka o kwe omume iji njirimara a; ọgwụgwọ okpomọkụ nke alloy siri ike ga-eme ka njirimara anụ ahụ na arụ ọrụ ya dịkwuo mma.

ZZBETTER na-etinye onwe ya n'ịmepụta ngwaahịa tungsten carbide dị elu na ọkwa ụwa. A na-eresị ngwaahịa anyị n'ọtụtụ mba na mpaghara ma mee nnukwu ihe ịga nke ọma n'ahịa ụlọ.

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.
