Ọdịiche dị n'etiti Tungsten na Tungsten Carbide

Na ụlọ ọrụ ọgbara ọhụrụ, ngwaahịa tungsten carbide aghọwo ngwá ọrụ na-ewu ewu. Na tungsten na-adịghị nanị eji maka bọlbụ. N'isiokwu a, anyị ga-ekwu maka ọdịiche dị n'etiti tungsten na tungsten carbide. Edemede a ga-akọwapụta otu a:

1. Gịnị bụ tungsten?

2. Gịnị bụ tungsten carbide?

3. Ọdịiche dị n'etiti tungsten na tungsten carbide.

Kedu ihe bụ tungsten?

A chọtara Tungsten na mbụ na 1779, a makwaara ya dị ka "nkume dị arọ" na Swedish. Tungsten nwere ebe mgbaze kachasị elu, ọnụọgụ mgbasawanye kachasị dị ala, yana nrụgide vepo kacha ala n'etiti ọla. Tungsten nwekwara ezigbo elasticity na conductivity.

Kedu ihe bụ tungsten carbide?

Tungsten carbide bụ alloy nke tungsten na carbon. A maara Tungsten carbide dị ka ihe nke abụọ kachasị sie ike n'ụwa, na-esote diamond. E wezụga isi ike, tungsten carbide nwekwara ezigbo nguzogide eyi, nguzogide corrosion, nguzogide ujo, na ịdịte aka.

Ọdịiche dị n'etiti tungsten na carbide tungsten

Anyị ga-ekwu maka ọdịiche dị n'etiti tungsten na tungsten carbide n'akụkụ ndị a:

1. Mgbanwe mgbanwe

Tungsten nwere modul elastic buru ibu nke 400GPa. Agbanyeghị, tungsten carbide nwere nke buru ibu nke gburugburu 690GPa. Ọtụtụ mgbe, ihe isi ike na-ejikọta modul na-agbanwe. Modul dị elu nke ngbanwe nke tungsten carbide na-egosi isi ike dị elu na nguzogide dị elu na nrụrụ.

2. Ọkpụkpụ modul

Module shear bụ oke nke nrụgide shiee na njiri nke shi, nke a na-akpọkwa modulus nke siri ike. N'ikwu okwu n'ozuzu, ọtụtụ nchara nwere modul gburugburu 80GPa, tungsten nwere ugboro abụọ, yana tungsten carbide ugboro atọ.

3. ike na-amịpụta ihe

Ọ bụ ezie na tungsten na tungsten carbide nwere ezigbo ike na ike siri ike, ha enweghị ike ịmị mkpụrụ. N'ozuzu, ike ike nke tungsten dị gburugburu 350MPa, nke tungsten carbide dị gburugburu 140MPa.

4. Thermal conductivity

Igwe ọkụ ọkụ bụ ihe dị mkpa mgbe a na-eji ihe eji eme ihe na gburugburu ebe okpomọkụ dị elu. Tungsten nwere conductivity thermal dị elu karịa tungsten carbide. Tungsten nwere nkwụsi ike nke okpomọkụ, yabụ na ọ dabara maka ụfọdụ ngwa ọkụ, dị ka filaments, tubes, na mkpuchi ọkụ.

5. Isi ike

Tungsten nwere ike nke 66, ebe tungsten carbide nwere ike nke 90. Tungsten carbide nwere tungsten na carbon, n'ihi ya, ọ bụghị nanị na ọ nwere àgwà ọma nke tungsten, ma ọ nwekwara ike na nkwụsi ike nke carbon.

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.
