Kawm txog cov khoom ntawm Magnesium Alloy Magnetron Sputtering Aluminium Txheej los ntawm Lub Tshuab Nqus Tsev
Aluminium tiv thaiv zaj duab xis yog coated rau saum npoo ntawm AZ31 magnesium alloy los ntawm ultra-vacuum magnetron sputtering txheej khoom. Qhov muaj pes tsawg leeg thiab micromechanical zog ntawm lub txheej tau kawm los ntawm kev siv glow discharge spectroscopy tsom xam thiab nanoindentation / khawb kev xeem thev naus laus zis. Kev faib tawm ntawm zaj duab xis tob. Cov txiaj ntsig tau pom tias cov txheej txheem txhuas yog tsim rau ntawm qhov chaw ntawm magnesium alloy substrate, thiab muaj cov txheej txheem hloov pauv ntawm txheej txheej thiab substrate. Qhov saum npoo hardness thiab elastic modulus ntawm aluminium txheej yog siab dua li ntawm magnesium alloy substrate, thiab txo nrog qhov tob. Nws tau zoo ua ke nrog cov substrate thiab nthuav tawm qee yam plasticity, thiab cov yeeb yaj kiab aluminized yog qhov zoo rau kev tsim cov txheej txheem tiv thaiv ntawm qhov chaw ntawm magnesium alloy.
Nyob rau hauv ib puag ncig corrosive, magnesium alloys tsis tuaj yeem tsim cov yeeb yaj kiab tiv thaiv rau ntawm qhov chaw zoo li txhuas alloys, thiab nws tuaj yeem ua rau galvanic corrosion li anode, uas txwv nws daim ntawv thov rau qee yam. Kev tsim cov txheej txheej tuab tuab lossis txheej txheej txheej txheej ntawm magnesium alloy tuaj yeem ua kom qeeb ntawm corrosion ntawm magnesium alloy [1-2]. Piv txwv li, txau cov txheej txheem tiv thaiv txhuas rau ntawm qhov chaw ntawm magnesium alloy tuaj yeem tsim cov txheej txheem tiv thaiv corrosion, tab sis qhov txheej txheej no yog thicker thiab qhov roughness ntau dua.
Magnetron sputtering txheej yog ib qho tseem ceeb ntawm lub cev vapor deposition txheej tshuab. Sputtering txheej yog hais txog kev sib tsoo ntawm qhov chaw ntawm lub hom phiaj cov khoom siv nrog cov khoom siv hluav taws xob nuclear hauv lub tshuab nqus tsev, thiab tua tawm cov atoms thiab lwm cov khoom hauv cov khoom siv los ntawm kev hloov pauv hloov pauv. Cov txheej txheem ntawm kev tso nws rau ntawm lub substrate los tsim ib zaj duab xis nyias. Kev siv cov magnetron sputtering los tsim cov yeeb yaj kiab tiv thaiv ntawm qhov chaw ntawm magnesium alloy los txhim kho corrosion kuj thiab hnav tsis kam ntawm cov hlau tau ua rau qee qhov kev ua tau zoo [5]. Nyob rau hauv daim ntawv no, cov khoom siv ultra-vacuum magnetron sputtering txheej yog siv los pleev xim rau saum npoo ntawm AZ31 magnesium alloy nrog magnetron sputtering txhuas tiv thaiv zaj duab xis. muaj pes tsawg leeg thiab micromechanical zog.
