Zotsatira zakuchizira mankhwala a aluminium a aluminium

Ndizodziwika bwino kuti aluminiyamu ndi ziwonetsero zake zamiyala mlengalenga, ndipo mwachilengedwe o oxide pamwamba pazigawo za aluminium ndi amorrous, zomwe zimapangitsa kuti mawonekedwe a aluminium alumule, ngakhale kanema wachilengedwe Tidzateteza malo a zigawo za aluminium yophika koma ndiowonda kwambiri, pafupifupi 4 mpaka 5 nm, ndipo ali ndi chidwi chachikulu komanso katundu wosauka. Sizingalepheretse bwino zachilengedwe za aluminium yopangidwa ndi media osiyanasiyana mumlengalenga.

Pambuyo pochotsa, zinthu zamagetsi za aluminium zimatha kupeza filimu yowala (kuchokera ku ma micrometers a micrometers ngakhale mazana a micrometers) omwe ndi owuma kwambiri kuposa filimu ya oxide. Kanemayu wochita bwino ma oxide amathandizidwanso. Kanema wa amorphide oxhuus amasinthidwa kukhala kanema wa Crystaline, ndipo pores atsekedwanso. Chifukwa chake, zokometsera zachitsulo sizisintha, ndipo mphamvu zogulira komanso mphamvu zamakina zimayenda bwino. Pambuyo pokoka, mawonekedwe okongoletsera amathanso kupezeka. Popeza magawo a aluminium a aluminium ali ndi mawonekedwe ambiri pambuyo pochotsa, njira zopangira aluminium zimagwiritsidwa ntchito kwambiri pazinthu zamakina a aluminium a aluminium . Mapulogalamu m'makampani amatha kukhala olembedwa mumitundu yotsatirayi.

. Mosasamala filimu ya oxide omwe apezeka kuchokera ku sulufuric acid yankho, acid acid sofution moyenera, pompopompompompom ndiyabwino kwambiri, mphika, ulusi wamakina, ndi monga.

. Mitundu yowala yowala komanso yowala ndi njira zitha kupezeka pa filimu ya oxide. Kuwoneka kwa njira zingapo zatsopano monga makutidwe ambiri a oxidation, matenthedwe ozimitsa moto, mapangidwe a tirigu, osamutsa makina opota , ndi zina zokongola kwambiri. Chotsanga chamtunduwu ndi gawo lokongoletsera komanso wosanjikiza wotsutsa.

(3) Monga chovuta kuvala chosakira: Mu sulfuric acid kapena oxfalic acid, mawonekedwe a filimu yolimba ndi hard wophatikizika. Zimagwiritsidwa ntchito bwino pazomwe zimagwira ntchito pachiwopsezo ndipo ili ndi mawonekedwe a mafuta ndi kuvala kukana, monga ma cylinders injini ndi mapikoni.

. Izi zili ndi tanthauzo lenileni ngati kusokonezeka kwamagetsi ndipo kungagwiritsidwe ntchito ngati capako. Izi zimagwiritsidwa ntchito zimatha kugwiritsidwanso ntchito pazida zina zamagetsi.

. Wosanjikiza wovomerezeka wa phosphoric acid akhoza kugwiritsidwa ntchito ngati chophatikizika chokhazikika pa seluminium.
