Birta Titanium-ka Ilkaha–ASTM F136 & F67 Saxnaanta-Darajada Saxda ah ee Qalabaynta Maqaarka & CAD/CAM

Soo saarista waxyaabaha gaarka ah, boolal bogsiinaya, ama isbarbardhigyada la gelinayo? Hel ulaha titanium-ka ilkuhu shahaadeysan ee leh ± 0.01 mm dhexroorka dulqaadka, dhammaystirka dusha sare Ra In ka yar ama la mid ah 0.8 µm, iyo warbixinnada tijaabada warshad- gooya dhererkaaga saxda ah, lagu soo raray 7-9days.

Ulaha Titanium Ilkaha ee Saxda ah – Waxaa loo farsameeyay Soo celinta Heerarka

Marka aad mishiinayso abutment caadadii ah ama analoogga maqaar-galaha, joogtaynta usha bilawga ah ayaa go'aamisa taam ahaanshaha badeecadaada ugu dambeysa iyo cimrigaaga. Ulahayaga titanium-ka ilkuhu waxa si gaar ah loogu soo saaray codsiyada ilkaha CAD/CAM, ee maaha baararka warshadaha dib loogu soo celiyay sidii "darajada caafimaadka." Ul kastaa waxay la kulantaa ASTM F136 (Grade 5 Ti-6Al-4V ELI) ama ASTM F67 (Fasalka 2 ganacsi ahaan saafi ah) - labada heer ee caalamiga ah ee titanium la geliyo.

Waa maxay sababta aan u doorano ulaha Titanium-kayaga?

1. La Xaqiijiyay Heerarka Fasalka Maqaar-Gaarka-Ma Jiro Gaaban

Waxaan bixinaa ulaha leh Warbixinada Tijaabada Millidhan (MTR) oo ay ku qoran yihiin sida saxda ah ee kiimikada, xoogga xajinta, xoogga dhalidda, iyo dhererka. Fasalka 5 ELI waxa ku jira ogsijiin waa in ka yar ama la mid ah 0.13% iska caabin daal sare ah– oo muhiim u ah darbiyada dhuuban. Fasalka 2 waxa uu bixiyaa ductility heer sare ah (Ka weyn ama la mid ah 20% elongation) bogsiinta boolal iyo boosteejada wareejinta.

2. Dulqaad adag oo loogu talagalay Mashiinnada la saadaalin karo

Dulqaadka dhexroorka: ± 0.01 mm (dhulka iyo la safeeyey)

Toosanaan: In ka yar ama la mid ah 0.1 mm dhererka 300 mm

Dhamaystirka dusha sare: Ra In ka yar ama la mid ah 0.8 µm (dhul aan dhexda lahayn, aan oksaydh lahayn)

Ma jiraan cillado dusha sare oo qarsoon, ma laha calaamado sheeko-xariir ah, ma jiro ovality - Lathe CNC-gaaga Swiss wuxuu u shaqeeyaa si habsami leh, mar kasta.

3. Iska yaree dhererkaaga saxda ah–Yaree qashinka

Waxaan bixinaa ulaha dherer kasta laga bilaabo 10 mm ilaa 3000 mm. Dhexroorka caadiga ah: 1.0 mm, 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm, 3.5 mm, 4.0 mm, 4.5 mm, 5.0 mm, 6.0 mm, 8.0 mm, 10.0 mm. Ma u baahan tahay dhexroor aan caadi ahayn? Kaliya weydii-waxaan bixinaa dhexroor gaar ah ilaa 50 mm.

4. Baafin buuxda - Laga bilaabo Ingot ilaa Colletkaaga

Ul kasta waxa lagu xardhay leysarka nambarada dufcada (marka la codsado dhexrooryada waaweyn). Waxaad walxaha dib ugu soo celin kartaa isbuunyada titanium-ka asalka ah - lagama maarmaanka u ah ISO 13485 iyo u hoggaansanaanta FDA.

5. Wakhtiyada Hogaaminta Degdega ah–Shaybaadhkaagu ha socdo

Dhexroorka caadiga ah iyo dhererka markabka gudahooda 3-5 maalmood oo shaqo. Dhexrooryada gaarka ahi waxay caadi ahaan ka baxaan bakhaarkayaga 10-12 maalmood gudahood. Ma jiro dalabka ugu yar ee cabbirrada caadiga ah.

Xagee Loo Isticmaalaa Ulaha Titanium-ka Ilkaha?

Waxyaabaha gaarka ah ee CAD/CAM (saldhigyada titanium ee taajka iyo buundooyinka)

Waxyaalaha bogsiinta & boolasha bogsashada

Ku dheji analogs & boosteejada wareejinta

Tilmaamaha qaliinka & qaybaha ku meel gaarka ah

implants-yar-yar oo orthodontic ah (qalabka barkinta ku-meel-gaarka ah - TADs)

Tilmaamaha Farsamada Degdegga ah (Qaabka Qoraalka)

Fasalka 2 (Ganacsi ahaan saafi ah, ASTM F67)

Xoog xajin: Ka weyn ama la mid ah 345 MPa

Yield strength: >=275 MPa

Kordhinta: Ka weyn ama la mid ah 20%

Adag: In ka yar ama la mid ah 200 HV

Waxa ugu fiican: Qalab bogsiinta, laqabsiga wareejinta, qaybaha aan rarka qaadin

Fasalka 5 (Ti-6Al-4V ELI, ASTM F136)

Xoogga xajinta: 860 - 965 MPa

Awoodda wax-soo-saarka: 795 - 830 MPa

Kordhinta: Ka weyn ama la mid ah 10%

Adag: In ka yar ama la mid ah 350 HV

Waxa ugu fiican: Gawaarida rarka qaada, naqshadaha gidaarada khafiifka ah, baararka lagu rakibo

Labada darajooyinba waxay diyaar u yihiin dulqaad dhexroor adag oo isku mid ah oo ah ± 0.01 mm iyo dhammaystirka dusha sare Ra In ka yar ama la mid ah 0.8 µm.
