Mitundu Yoyambira Yopaka Zomaliza

Mphero yomaliza ya carbide imadziwikanso kuti mphero ya simenti ya carbide. Kuuma kwa chida chokha nthawi zambiri kumakhala pakati pa HRA88-96 madigiri. Koma ndi zokutira pamwamba, kusiyana kumabwera. Njira yotsika mtengo kwambiri yopititsira patsogolo magwiridwe antchito a mphero ndikuwonjezera zokutira zoyenera. Ikhoza kuwonjezera moyo wa chida ndi ntchito.

Kodi zokutira zoyambira za mphero pamsika ndi ziti?

1. TiN - Titanium Nitride - zokutira zosagwirizana ndi ntchito zonse

TiN ndiye zokutira zolimba zomwe zimavala komanso zosamva ma abrasion. Amachepetsa kukangana, amawonjezera kukhazikika kwamankhwala ndi kutentha, ndipo amachepetsa kumamatira kwazinthu zomwe zimachitika nthawi zambiri popanga zitsulo zofewa. TiN ndi yoyenera pazida zokutira zopangidwa ndi simenti zobowola, zodulira mphero, zida zodulira, matepi, ma reamers, mipeni, zida zodulira, zida zometa ndi zopindika, matrices, ndi mafomu. Popeza ndi biocompatible, itha kugwiritsidwa ntchito pazida zamankhwala (opaleshoni ndi mano) ndi zida zoyikidwa. Chifukwa cha kamvekedwe kake ka golide, TiN yapeza kugwiritsidwa ntchito kwambiri ngati zokutira zokongoletsa. Chophimba cha TiN chogwiritsidwa ntchito chimachotsedwa mosavuta kuzitsulo zachitsulo. Kukonzanso kwa zida kumatha kuchepetsa kwambiri mtengo, makamaka pogwiritsa ntchito zida zodula.

2.TiCN - Titanium Carbo-Nitride - zokutira zosagwira motsutsana ndi dzimbiri zomatira

TiCN ndiyabwino kwambiri pazolinga zonse. TiCN ndi yolimba komanso yosamva mphamvu kuposa TiN. Itha kugwiritsidwa ntchito kuvala zida zodulira, kukhomerera ndi kupanga zida, zida za jekeseni wa nkhungu, ndi zida zina zobvala. Popeza ndi biocompatible, itha kugwiritsidwa ntchito pazida zamankhwala ndi zida zoyika. Kuthamanga kwa makina kumatha kuonjezedwa ndipo moyo wa zida ukhoza kukulitsidwa ndi 8x pakudalira kugwiritsa ntchito, kuziziritsa, ndi zina zamakina. Chophimba cha TiCN chikulimbikitsidwa kuti chigwiritsidwe ntchito podula choziziritsa mokwanira chifukwa chakuchepa kwake kwa kutentha. Chophimba cha TiCN chomwe chinagwiritsidwa ntchito chimavulidwa mosavuta ndipo chida chimakutidwanso. Kukonzanso zida zodula kumatha kuchepetsa kwambiri ndalama.

3. AlTiN-The Aluminium-Titanium-Nitride zokutira ()

Ndi mankhwala opangidwa ndi zinthu zitatu za aluminiyamu, titaniyamu, ndi nayitrogeni. Kuchuluka kwa zokutira kumakhala pakati pa 1-4 ma micrometer (μm).

Mbali yapadera ya zokutira za AlTiN ndizovuta kwambiri kutentha ndi okosijeni. Izi ndi zina chifukwa cha kuuma kwa nano kwa 38 Gigapascal (GPa). Zotsatira zake, zimatsatira kuti ndondomeko yophimba ngakhale kuti ili ndi liwiro lapamwamba kwambiri komanso kutentha kwapamwamba kwambiri kumakhalabe kokhazikika. Poyerekeza ndi zida zopanda zokutira, zokutira za AlTiN, kutengera momwe zimagwiritsidwira ntchito, zimawonjezera moyo wautumiki kunthawi khumi ndi zinayi.

Chophimba chokhala ndi aluminiyamu kwambiri ndi choyenera kwambiri pazida zolondola, zomwe zimadula zinthu zolimba monga chitsulo (N/mm²)

Kutentha kwakukulu kwa ntchito ndi 900 ° Celcius (pafupifupi 1,650 ° Fahrenheit) ndikuyerekeza ndi zokutira kwa TiN ndi 300 ° Celcius kukana kwambiri kutentha.

Kuziziritsa sikokakamizidwa. Nthawi zambiri, kuziziritsa kumawonjezera moyo wautumiki wa chida.

Monga tafotokozera mu zokutira za TiAlN, ziyenera kukumbukiridwa kuti zonse zophimba ndi zida zachitsulo ziyenera kukhala zoyenera kugwiritsa ntchito muzinthu zolimba. Ichi ndichifukwa chake tavala zobowola zapadera zopangidwa ndi tungsten-carbide ndi AlTiN.

4.TiAlN - Titanium Aluminium Nitride - zokutira zosagwira ntchito zodula kwambiri

TiAlN ndi zokutira zolimba kwambiri komanso kukana kwamafuta ambiri komanso okosijeni. Kuphatikizika kwa aluminiyamu kunakulitsa kukana kwamafuta kwa zokutira za PVD zophatikiza izi potengera zokutira wamba wa TiN ndi 100 ° C. TiAlN imakhala yokutidwa pazida zodula kwambiri zomwe zimagwiritsidwa ntchito pamakina a CNC popanga zida zolimba kwambiri komanso pamikhalidwe yodula kwambiri. TiAlN ndiyoyenera makamaka kwa odula zitsulo zolimba za monolithic, zobowola, zida zodulira, ndi mipeni yopangira. Itha kugwiritsidwa ntchito pamakina owuma kapena pafupi ndi makina owuma.

Ngati muli ndi chidwi ndi zinthu za tungsten carbide ndipo mukufuna zambiri ndi zambiri, mutha KULUMIKIZANA NAFE pa lamya kapena makalata kumanzere, kapena KUTITUMIZIRA MAIL pansi pa tsambali.
