II. Ubi ngwa na Swing zuru ezu
1. Ubi Ngwá Ọrụ
- Titanium Carbide (TiC): Ọtụtụ mgbe na-eje ozi dị ka mkpuchi na ngwaọrụ! Ihe mkpuchi TiC siri ike - nke siri ike ma na-eyi - na-etinye "ihe agha nchebe" n'elu igwe ọsọ ọsọ na ngwaọrụ carbide cimented.

Dị ka ihe atụ, na mkpuchi nke finishing-egwe ọka cutters, ọ na-enyere ngwa ngwa na kwụsie ike ọnwụ.
- Silicon Carbide (SiC): "Onye mmụta kachasị elu" n'etiti ngwaọrụ seramiiki! Ngwá ọrụ seramiiki dabeere na SiC nwere nnukwu nguzogide okpomọkụ na nkwụsi ike kemịkal. Mgbe ị na-egbutu alloys siri ike dị elu (dị ka nickel-based alloys) na ihe ndị na-agbaji agbaji (dị ka igwe nkedo), ha anaghị adị mfe ịrapagidesi ike ngwá ọrụ ma nwee ngwa ngwa. Otú ọ dị, n'ihi brittleness, ha na-adaba adaba maka imecha na obere nkwụsị nkwụsị na nkenke dị elu.

2. Yiri – Ubi ihe na-eguzogide
- Titanium Carbide (TiC): Na-arụ ọrụ dị ka onye mmeri na-eyi uwe na-eguzogide ọgwụ n'ụdị ziri ezi! Dịka ọmụmaatụ, na ntụ ntụ metallurgy ebu, mgbe ị na-agbanye ntụ ntụ ígwè, ntinye TiC na-eyi - na-eguzogide ọgwụ ma nwee oke dị elu, na-eme ka akụkụ ndị a na-agbanye aka nwere akụkụ ziri ezi na ebe dị mma, na-adịghịkwa enwe ike "adịghị arụ ọrụ" n'oge mmepụta oke.
- Silicon Carbide (SiC): Enyere "buffs abụọ" nke nguzogide eyi na elu - okpomọkụ na-eguzogide! Rollers na bearings na nnukwu ọkụ ọkụ nke siC ceramics anaghị eme ka ọ dị nro ma ọ bụ yikwasị ọbụna karịa 1000 ℃. Ọzọkwa, nozzles n'ime ngwá ọrụ mgbawa ájá nke SiC mere nwere ike iguzogide mmetụta nke ụmụ irighiri ájá, na ndụ ọrụ ha dị ọtụtụ ugboro karịa nke ígwè nozzles nkịtị.
- Carbide cemented (WC-Co): "Ọkachamara na-eyi uwe na-eguzogide ọgwụ"! Ezé carbide e ji ciment kpụọ n'ime mkpọmkpọ ebe m nwere ike ịzọpịa nkume na-enweghị mmebi; Ndị na-egbu osisi carbide simented na ngwaọrụ igwe ọta nwere ike iguzogide ala na nkume aja, ma nwee ike “dowe ahụ iru ala” ọbụlagodi mgbe ha gbachara ọtụtụ puku mita. Ọbụna wiil eccentric na moto ịma jijiji ekwentị na-adabere na carbide cemented maka nguzogide iyi iji hụ na ịma jijiji kwụsiri ike.
3. Eletrọnịkị / Semiconductor Field
- Titanium Carbide (TiC): Na-apụta na ụfọdụ ngwa eletrọnịkị nke na-achọ elu - okpomọkụ na akwa mkpuchi mkpuchi! Dị ka ihe atụ, na electrodes nke elu - ike electron tubes, TiC nwere elu - okpomọkụ na-eguzogide, ezi eletriki conductivity, na-eyi na-eguzogide, na-enyere kwụsie ike ịrụ ọrụ na elu - okpomọkụ gburugburu na hụ na eletrọnịkị mgbaàmà nnyefe.
- Silicon Carbide (SiC): " ọkacha mmasị ọhụrụ na semiconductor "! SiC semiconductor ngwaọrụ (dị ka SiC ike modul) nwere ọmarịcha elu - ugboro, elu - voltaji, na elu - okpomọkụ arụmọrụ. Mgbe ejiri ya na ụgbọ ala eletrik na ndị ntụgharị fotovoltaic, ha nwere ike imeziwanye arụmọrụ ma belata olu. Ọzọkwa, SiC wafers bụ "ntọala" maka ịmepụta elu - ugboro na elu - ibe okpomọkụ, ma na-atụ anya ya na ọdụ ụgbọ ala 5G na avionics.
- Carbide cemented (WC-Co): "Ngwaọrụ ziri ezi" na nhazi eletrọnịkị! Ngwunye carbide cimented maka mkpọpu PCB nwere ike inwe dayameta dị obere ka 0.1mm ma nwee ike ịkụ ala nke ọma na-enweghị imebi ngwa ngwa. Ihe ntinye carbide nke cimented na ihe ngwungwu mgbawa nwere oke nkenke ma na-eyi nkwụsi ike, na-ahụ na ngwugwu mgbawa ziri ezi na kwụsiri ike.
III. Kedu ka esi ahọrọ?
- Maka oke isi ike na nguzogide iyi→ Họrọ titanium carbide (TiC)! Dịka ọmụmaatụ, na mkpuchi mkpuchi nkenke nke ọma na ihe mkpuchi ngwá ọrụ siri ike, ọ nwere ike "nagide" iyi na ịnọgide na-enwe nkenke.
- Maka elu - nguzogide okpomọkụ, nkwụsi ike kemịkalụ, ma ọ bụ na-arụ ọrụ na semiconductors / elu - ngwaọrụ ugboro→ Họrọ silicon carbide (SiC)! Ọ dị mkpa maka ihe ọkụ ọkụ ọkụ dị elu yana ibe ike SiC.
- Maka ịrụ ọrụ zuru oke n'ozuzu ya, na-ekpuchi ihe niile site na ịkpụ na-eyi - ngwa na-eguzogide ọgwụ→ Họrọ carbide cimented (WC – Co)! Ọ bụ "ihe ọkpụkpọ na-agbanwe agbanwe" na-ekpuchi ngwá ọrụ, mgbatị na iyi - akụkụ ndị na-eguzogide ọgwụ.
