ʻIke ʻia ka ʻino Filiform ma luna o ka alumini
Piliform corrosion He ʻano corrosion kūikawā e ʻike nui ʻia ana ma ka alumini. Ua like ka hanana me kahi ilo e kolo ana ma lalo o ka uhi, e hoʻomaka mau ana mai kahi ʻoki ʻoki a i ʻole kahi pōʻino o ka papa.
Hoʻomaka maʻalahi ka palaka Filiform ke ʻike ʻia ka mea i uhi ʻia i ka paʻakai i hui pū ʻia me nā mahana 30/40 ° C a me ka haʻahaʻa pili 60-90%. No laila ua kaupalena ʻia kēia pilikia i nā wahi kahakai a pili pū me ka hui pū ʻana o nā alumini alumini a me ka mālama mua ʻana.
No ka hōʻemi ʻana i nā ʻino filiform e ʻōlelo ʻia e hōʻoia i kahi etching alkaline kūpono a ukali ʻia e kahi holoi ʻakika ma mua o ka hoʻololi ʻana i ka chrome. Manaʻo ʻia ka wehe ʻana i ka ʻili alumini he 2g/m2 (ka liʻiliʻi he 1.5g/m2).
ʻO ka anodizing e like me ka hoʻomaʻamaʻa mua ʻana no ka alumini he ʻenehana i hoʻomohala kūikawā e pale ai i ka corrosion filiform. Pono kahi kaʻina hana anodization kūikawā inā he mea nui ka mānoanoa a me ka porosity o ka papa anodization.
