Kafukufuku akupita patsogolo mu titaniyamu aluminium alloy sputtering coating chandamale

Titanium aluminium alloy ndi chandamale cha alloy sputtering pakuyika vacuum. Titaniyamu zotayidwa aloyi mipherezero ndi makhalidwe osiyana angapezeke mwa kusintha zili titaniyamu ndi zotayidwa mu aloyi. Titaniyamu aluminium intermetallic mankhwala ndi zida zolimba komanso zosasunthika zokhala ndi kukana kwabwino. Iwo yokutidwa ndi wosanjikiza wa titaniyamu zotayidwa intermetallic mankhwala pamwamba zida wamba kudula, amene mogwira kuwonjezera moyo utumiki wa zida. Ngati sputtering ikuchitika ndi nayitrogeni kumaliseche arc kuyambira, mkulu kuuma ndi otsika mikangano coefficient pamwamba chigoba nkhope angapezeke, amene makamaka oyenera ❖ kuyanika pamwamba zida zosiyanasiyana, zisamere pachakudya ndi mbali zina pachiwopsezo. Chifukwa chake, ili ndi chiyembekezo chogwiritsa ntchito bwino mumakampani opanga makina.

Kukonzekera kwa titaniyamu aluminium alloy targets ndizovuta. Malinga ndi chithunzi cha gawo la titaniyamu zotayidwa aloyi, zosiyanasiyana intermetallic mankhwala akhoza kupangidwa pakati titaniyamu ndi zotayidwa, kumabweretsa processing brittleness mu titaniyamu zotayidwa aloyi. Makamaka pamene aluminiyamu zili mu aloyi kuposa 50% (atomiki chiŵerengero), ndi makutidwe ndi okosijeni kukana aloyi amachepetsa mwadzidzidzi ndi makutidwe ndi okosijeni kwambiri. Pa nthawi yomweyo, exothermic Kukula pa ndondomeko aloyi mosavuta kupanga thovu, shrinkage pores, ndi porosity, chifukwa mkulu porosity wa aloyi ndi kulephera kukwaniritsa kachulukidwe zofunika chandamale zakuthupi. Pali njira ziwiri zazikulu zopangira titaniyamu aluminium alloys:

1. Njira yamphamvu yotentha yapano

Njirayi imagwiritsa ntchito chipangizo chomwe chingathe kupeza zamakono zamakono, zomwe zimatenthetsa titaniyamu ufa ndi ufa wa aluminiyamu, zimagwiritsa ntchito mphamvu, ndipo zimapangitsa kuti aluminiyamu ndi titaniyamu zigwirizane ndi kupanga titaniyamu aluminium alloy targets. Kachulukidwe wa titaniyamu aluminium alloy chandamale chandamale chokonzedwa ndi njirayi ndi> 99%, ndipo kukula kwake kwambewu ndi ≤ 100 μ m. Chiyero> 99%. Mitundu yosiyanasiyana ya titaniyamu aluminium alloy chandamale chandamale ndi: titaniyamu zili 5% mpaka 75% (chiŵerengero cha atomiki), ndipo zina zonse ndi aluminium. Njirayi imakhala yotsika mtengo komanso yotsika mtengo, ndipo imatha kukwaniritsa zofunikira zamakampani akuluakulu.

2, Hot isostatic kukanikiza sintering njira

Njirayi imasakaniza ufa wa titaniyamu ndi ufa wa aluminiyamu, kenako imadzaza ufa, kuzizira kwa isostatic kukanikiza kusanachitike, njira yochotsera mpweya, kenako ndikutentha kwa isostatic. Pomaliza, sintering ndi processing ikuchitika kupeza titaniyamu zotayidwa aloyi zolinga. Titaniyamu aluminium alloy chandamale yokonzedwa ndi njirayi ili ndi mawonekedwe a kachulukidwe kwambiri, palibe pores, palibe porosity ndi tsankho, kapangidwe ka yunifolomu, ndi njere zabwino. Njira yotentha ya isostatic ndiyo njira yayikulu yokonzekera titaniyamu aluminium alloy sputtering zolinga zomwe zimafunidwa ndi makampani okutira.
