304 ipu uamea u'amea 304 ipu uamea u'amea
Fa'amatalaga Puupuu:
Fa'alumaina ipu u'amea uamea lamolemole, ma le palasitika maualuga, faigata ma le malosi fa'ainisinia, acid, kasa alkaline, fofo ma isi ala o faasalalauga corrosion.O se u'amea u'amea e le 'ele gofie, ae e le'o matua'i fa'atauva'a.
E tusa ai ma le faagasologa o le taʻavale vevela ma le malulu malulu, e mafai ona vaevaeina uʻamea i ituaiga 5: AUSTENITE, austenite-ferrite, ferrite, martensite ma le faʻamaʻaina o timuga.E manaʻomia le faʻafefe o le oxalic acid, sulfuric acid-ferric sulfate, nitric acid-hydrofluoric acid, sulfuric acid-copper sulfate, phosphoric acid, formic acid, acetic acid ma isi vailaʻau.E faʻaaogaina lautele i vailaʻau, meaʻai, vailaʻau, fai pepa, suauʻu, malosi atomic ma isi alamanuia, ma fale, umukuka, laulau, taʻavale, meafale ma vaega eseese ma vaega.
