Titanium txhuas Nitride

Titanium aluminium nitride ( TiAlN ) los yog txhuas titanium nitride ( AlTiN ; rau txhuas txheem ntau dua 50%) rau ib pawg ntawm cov pa coatings uas muaj cov ntsiab lus ntawm cov xim txhuas thiab titanium, thiab nitrogen. Plaub yam tseem ceeb (cov ntsiab lus hlau 100 ntawm.%) Muab tso rau hauv qhov ntsuas ntawm lub cev los ntawm kev siv lub cev vapor deposition kev:

◆ Ti50Al50N (industrially ua tswvcuab los ntawm lub tuam txhab CemeCoat (tam sim no Cemecon) Aachen, BRD, pab pawg T. Leydecker ca. 1989)

◆ Al55Ti45N (Industrially tswv yim los ntawm lub tuam txhab Metaplas Ionon (tam sim no Sulzer Metaplas), Bergisch Gladbach, BRD, pab pawg J. Vetter ca. 1999)

❑ Al60Ti40N (industrially ua tswvcuab los ntawm lub tuam txhab Kobe Steel, Kobe, Nyiv, ca. 1992)

◆ Al66Ti34N (Industrially tswv yim los ntawm lub tuam txhab Metaplas (tam sim no Sulzer Metaplas) pawg J. Vetter ca. 1996).

Cov laj thawj tsim nyog vim TiAlN coatings outperform ntshiab Titanium nitride (TiN) coatings yog suav tias yog:

◆ Ua rau oxidation tsis zoo rau cov nroj tsuag kom txias vim yog tsim los ntawm kev tiv thaiv aluminium-oxide txheej ntawm qhov chaw

◆ Ua kom muaj zog hauv cov yeeb yaj kiab tshiab uas yog vim muaj cov qauv kev hloov hauv cov qauv thiab cov txheej txheem daws teeb meem

◆ Hnub nyoog zawm ntawm cov coatings ntawm qhov kub txias rau cov cuab yeej ua haujlwm vim spinodal decomposition ntawm TiAlN rau TiN thiab cubic AlN

Lub hnub nyoog hardening phenomena tau pom tias tuaj nyob rau hauv ib tug mismatch nyob rau hauv lub quantum mechanical hluav taws xob ntawm TiN thiab AlN
