Hunhu uye mashandisirwo eTitanium Carbide, Silicon Carbide, uye Cemented Carbide Materials.

Mu "material universe" yekugadzira maindasitiri, titanium carbide (TiC), silicon carbide (SiC), uye simende carbide (kazhinji yakavakirwa tungsten carbide - cobalt, nezvimwewo) matatu anopenya "nyeredzi zvinhu". Nezvimiro zvavo zvakasiyana, vanotamba mabasa akakosha munzvimbo dzakasiyana siyana. Nhasi, tichatora -- zvakadzama tarisa mutsauko wezvivakwa pakati pezvinhu zvitatu izvi uye mamiriro azvinogoneka!

I. Musoro - kusvika - Musoro Kuenzanisa Kwezvinhu Zvezvinhu

Material Type	Kuoma (Reference Value)	Density (g/cm³)	Pfeka Resistance	High – Temperature Resistance	Kugadzikana Kwemakemikari	Kuoma
Titanium Carbide (TiC)	2800 - 3200HV	4.9 - 5.3	Yakanakisa (inotongwa nezvikamu zvakaoma)	Yakagadzikana pa ≈1400 ℃	Inopikisa kune acids uye alkalis (kunze kwekusimba oxidizing acids)	Zvishoma zvishoma (brittleness inonyanya kuoneka)
Silicon Carbide (SiC)	2500 - 3000HV (yeSiC ceramics)	3.1 – 3.2	Yakasarudzika (yakatsigirwa necovalent bond chimiro)	Yakagadzikana pa ≈1600 ℃ (mune ceramic state)	Yakanyanya kusimba (inopokana kune mazhinji emakemikari media)	Moderate (brittle in ceramic state; makristasi ega ane kuoma)

Kuparara kweNzvimbo:

• Titanium Carbide (TiC): Kuoma kwayo kuri pedyo neiyo yedhaimani, zvichiita kuti ive nhengo yemhuri yemhando yepamusoro-yakaoma. Kuwanda kwayo kwepamusoro kunobvumira kumira kwakasimba mumaturusi chaiwo anoda "kurema". Nekudaro, ine yakakwira brittleness uye inogara ichipfava pasi pesimba, saka inonyanya kukodzera kune static, yakaderera - kukanganisa kucheka / kupfeka - inopikisa mamiriro. Semuenzaniso, inowanzoshandiswa sechifukidzo pazvishandiso. Iyo TiC yekupfekedza yakanakisa - yakaoma uye kupfeka - inoshingirira, sekuisa "zvombo zvekudzivirira" pakakwirira - simbi yekumhanya uye simende maturusi ecarbide. Kana uchicheka simbi isina tsvina uye alloy simbi, inogona kumira kutonhora kwakanyanya uye kuderedza kusakara, ichiwedzera zvakanyanya hupenyu hwematurusi. Semuyenzaniso, mukuputira kwekupedzisa milling cutters, inogonesa kucheka nekukurumidza uye kwakagadzikana.
• Silicon Carbide (SiC): A "mutambi wepamusoro mune yakakwirira - tembiricha kuramba"! Inogona kuchengetedza kushanda kwakagadzikana pamusoro pe1600 ℃. Munzvimbo yeceramic, kugadzikana kwayo kwemakemikari kunoshamisa uye haatombopindirana neasidhi uye alkalis (kunze kwevashoma vakaita sehydrofluoric acid). Nekudaro, brittleness inyaya yakajairika yezvigadzirwa zveceramic. Zvakadaro, imwe chete - crystal silicon carbide (yakadai se4H - SiC) yakavandudza kuomarara uye iri kuita kudzoka mune semiconductors uye yakakwirira - frequency zvishandiso. Semuyenzaniso, SiC - based ceramic maturusi "vadzidzi vepamusoro" pakati pematurusi eceramic. Vane yakakwirira - kupisa kwekushisa uye kugadzikana kwemakemikari. Paunenge uchicheka zvakakwirira-zvakaoma alloys (senge nickel-based alloys) uye brittle zvinhu (zvakadai sesimbi yakakandwa), hazviitike kune zvigadziro zvinonamatira uye zvinononoka kupfeka. Zvisinei, nekuda kwebrittleness, ivo vakanyanya kukodzera kupedzisa nekucheka kushoma kwakakanganiswa uye yakakwirira chaiyo.
• Cemented Carbide (WC - Co): "Mutambi wepamusoro-tier mumunda wekucheka"! Kubva maturusi emidziyo kuenda kuCNC milling cutters, kubva simbi yekugaya kusvika kudombo rekuchera, inogona kuwanikwa kwese kwese. Cemented carbide ine yakaderera Co yemukati (yakadai seYG3X) yakakodzera kupedzisa, nepo iyo ine yakakwira Co yemukati (yakadai seYG8) ine yakanaka maitiro ekupikisa uye inogona kubata hutsinye machining zviri nyore. Iwo maWC akaoma zvikamu ane basa re "kumira" kupfeka, uye Co binder inoita se "glue" kubata zvidimbu zveWC pamwechete, kuchengetedza kuoma uye kuoma. Kunyangwe iyo yakakwirira-yekudzivirira tembiricha haina kunaka semaviri ekutanga, kuita kwayo kwakaringana kuita kunoita kuti ive yakakodzera kune yakakura siyana yezviitiko kubva pakucheka kusvika pakupfeka - inodzivirira zvikamu.

II. Minda Yekushandisa mune Yakazara Swing

1. Kucheka Tool Munda

• Titanium Carbide (TiC): Kazhinji inoshanda sejasi pamidziyo! Iyo yepamusoro - yakaoma uye inopfeka - inodzivirira TiC coating inoisa "zvombo zvekudzivirira" pane yakakwirira - yekumhanyisa simbi uye simende maturusi ecarbide. Kana uchicheka simbi isina tsvina uye alloy simbi, inogona kumira kutonhora kwakanyanya uye kuderedza kusakara, ichiwedzera zvakanyanya hupenyu hwematurusi. Semuenzaniso, mukuputira kwekupedzisa milling cutters, inogonesa kucheka nekukurumidza uye kwakagadzikana.
• Silicon Carbide (SiC): "Mudzidzi wepamusoro" pakati pematurusi eceramic! SiC - yakavakirwa ceramic maturusi ane yakakwirira - tembiricha kuramba uye kugadzikana kwemakemikari. Paunenge uchicheka zvakakwirira-zvakaoma alloys (senge nickel-based alloys) uye brittle zvinhu (zvakadai sesimbi yakakandwa), hazviitike kune zvigadziro zvinonamatira uye zvinononoka kupfeka. Zvisinei, nekuda kwebrittleness, ivo vakanyanya kukodzera kupedzisa nekucheka kushoma kwakakanganiswa uye yakakwirira chaiyo.
• Cemented Carbide (WC - Co): "Mutambi wepamusoro-tier mumunda wekucheka"! Kubva maturusi emidziyo kuenda kuCNC milling cutters, kubva simbi yekugaya kusvika kudombo rekuchera, inogona kuwanikwa kwese kwese. Cemented carbide ine yakaderera Co yemukati (yakadai seYG3X) yakakodzera kupedzisa, nepo iyo ine yakakwira Co yemukati (yakadai seYG8) ine yakanaka maitiro ekupikisa uye inogona kubata hutsinye machining zviri nyore.

2. Kupfeka - Resistant Component Field

• Titanium Carbide (TiC): Inoshanda se "kupfeka - inodzivirira shasha" mune chaiyo molds! Semuyenzaniso, muupfu metallurgy molds, kana uchitsikirira simbi poda, TiC inoisa inopfeka - isingachinji uye ine yakanyanya kurongeka, kuve nechokwadi chekuti zvikamu zvakatsikirirwa zvine zviyero zvakaringana uye nzvimbo dzakanaka, uye hazvitani "kutadza kushanda" panguva yekugadzirwa kwakawanda.
• Silicon Carbide (SiC): Yakapihwa "kaviri buffs" yekupfeka kuramba uye yakakwirira - tembiricha kuramba! Rollers uye mabhengi akakwira - tembiricha mavira akagadzirwa neSiC ceramics haapfave kana kupfeka kunyange pamusoro pe1000 ℃. Zvakare, mabhunu mune jecha midziyo yakagadzirwa neSiC inogona kumira kukanganiswa kwejecha zvimedu, uye hupenyu hwavo hwesevhisi hwakareba zvakapetwa kakati wandei kupfuura hweakajairwa simbi.
• Cemented Carbide (WC - Co): "Kupfeka kwakasiyana-siyana - kupikisa nyanzvi"! Mazino akaiswa simende mumigodhi yekuchera anogona kupwanya matombo pasina kukuvara; akasimirirwa carbide cutters pamaturusi emuchina wenhovo anogona kumira ivhu nematombo ejecha, uye anogona "kudzikama" kunyangwe mushure mekuita tunnel zviuru zvemamita. Kunyangwe iwo eccentric mavhiri munharembozha vibration motors anovimba necemented carbide yekupfeka kuramba kuti ive nechokwadi chekuzunguzika kwakadzikama.

3. Electronics / Semiconductor Field

• Titanium Carbide (TiC): Inoratidzika mune zvimwe zvinhu zvemagetsi zvinoda yakakwirira - tembiricha uye yakakwirira kupfeka kuramba! Semuenzaniso, mumagetsi emagetsi emagetsi emagetsi epamusoro-soro, TiC ine yakakwirira-yekudzivirira tembiricha, yakanaka magetsi conductivity, uye kupfeka kuramba, ichigonesa kushanda kwakagadzikana munzvimbo dzakakwirira-tembiricha uye kuve nechokwadi chekufambisa kwemasaini emagetsi.
• Silicon Carbide (SiC): "Itsva inofarira mumasemiconductors"! SiC semiconductor zvishandiso (senge SiC simba modules) ine yakanakisa yakakwira - frequency, yakakwira - voltage, uye yakakwirira - tembiricha kuita. Kana yakashandiswa mumotokari yemagetsi uye photovoltaic inverters, inogona kuvandudza zvakanyanya kushanda uye kuderedza huwandu. Zvakare, SiC wafers ndiyo "nheyo" yekugadzira yakakwirira - frequency uye yakakwirira - tembiricha machipisi, uye anotarisirwa zvakanyanya mu5G base zviteshi uye avionics.
• Cemented Carbide (WC - Co): "Chishandiso chakarurama" mukugadzirwa kwemagetsi! Cemented carbide drills for PCB drilling inogona kuva nedhayamita diki se0.1mm uye inogona kuboora chaiko pasina kutyora nyore. Cemented carbide inoisa mu chip kurongedza molds ine yakanyanya kurongeka uye kupfeka kuramba, kuve nechokwadi chekurongedza kwakaringana uye kwakagadzikana kwe chip pini.

III. Ungasarudza sei?

• Nokuda kwekuoma kwakanyanya uye kunyatsopfeka kusagadzikana→ Sarudza titanium carbide (TiC)! Semuenzaniso, mune chaiyo mold coatings uye super - hard tool coatings, inogona "kumira" kupfeka uye kuchengetedza zvakarurama.
• Kwepamusoro-tembiricha kuramba, kugadzikana kwemakemikari, kana kushanda pane semiconductors / yakakwirira - frequency zvishandiso→ Sarudza silicon carbide (SiC)! Iyo yakakosha kune yakakwirira - tembiricha yevira zvikamu uye SiC simba machipisi.
• Nekuita kwakaringana kuita kwese, kufukidza zvese kubva pakucheka kusvika pakupfeka - kuramba maapplication→ Sarudza simende carbide (WC - Co)! Iyo "mutambi anochinja-chinja" anovhara maturusi, zvibooreso, uye kupfeka - zvinoramba zvikamu.
