E tele ituaiga o sikulima apaau e vili e le tagata lava ia, ae tutusa uma uiga.E lima uiga autu.O meafaigaluega nei o loʻo faʻamatalaina uiga e lima o faʻailoga faʻapipiʻi apaʻau:

1. E masani ona faia i uamea carburized (99% o le aofaʻi o oloa).E mafai fo'i ona fa'aoga i u'amea u'amea po'o u'amea e leai ni u'amea.

2. E tatau ona fa'avevela le fa'avelaina o fa'avili fa'asili ma apaau.O meafaigaluega e ta'u atu ia te oe o fao sikulima u'amea uamea e tatau ona fa'ama'a, ma fao fao fao apaau e tatau ona fa'ama'a'a.Ina ia mafai ona faʻafeiloaʻi faʻamaʻi faʻapipiʻi e le tagata lava ia mea faʻainisinia ma faʻatinoga e manaʻomia e le tulaga masani.

3. Apa'au fa'avili fa'alila oloa e maualuga le ma'a'a i luga ma lelei le malosi autu.O lona uiga, "malu i totonu ma malosi i fafo".O meafaigaluega e taʻu atu ia te oe o se vaega tele lea o le faʻatinoga o manaʻoga o fao apaau e vili e le tagata lava ia.Afai e maualalo le maaa o luga, e le mafai ona viliina i totonu o le matrix;afai e leaga le malosi o le fatu, o le a malepe i le taimi lava e vili ai ma e le mafai ona faʻaaogaina.O le mea lea, "malulu i totonu ma malo i fafo" o fao sikulima fao ma apaau e fetaui ma manaoga o faatinoga.

4. O le pito i luga o le mea e sili ona lelei viliina siu ma apaau oloa manaʻomia togafitiga puipuiga luga, masani electroplating togafitiga.O meafaigaluega e taʻu atu ia te oe o luga o nisi oloa e manaʻomia ona togafitia i le phosphate (phosphating).Fa'ata'ita'iga: O fao e vili e le tagata lava ia ma fao apaau i luga o laupapa puipui e tele lava ina fa'apala
