O mea fa'apipi'i malosi maualuga o le a maua ai le mafiafia pe a fa'a'umea.Manaomia le gauai faapitoa.

O le fa'aleagaina o le hydrogen e masani ona fa'aalia i le tuai ona gau i lalo o le fa'alavelave.O loʻo i ai vaipuna taʻavale, fufulu, sikulima, vaipuna ma isi vaega uʻamea, i ni nai itula talu ona malepe le faʻapotopotoga, o le gau o le 40% ~ 50%.I le faagasologa o le faʻaaogaina o vaega faʻapipiʻi cadmium o se oloa faʻapitoa, sa i ai le gau gau, ma o se faʻafitauli autu a le atunuʻu na foia ma faia ai se faiga faʻamaʻi faʻamaʻi.E le gata i lea, o loʻo i ai nisi o le hydrogen embrittlement e leʻo faʻaalia le tuai o gau gau, e pei o le: faʻapipiʻi faʻamau (uaea uʻamea, uaea apamemea) ona o le tele o taimi o le faʻaogaina o le eletise ma le faʻapipiʻiina, e sili atu le ogaoga o le faʻaogaina o le hydrogen, e masani ona faʻaalia i le faʻaaogaina o se gaugau. fa'alavelave gau gau;O le mandrel o se fana, ina ua mavae ni nai taimi o chroming, na pau i lalo ma gau;O nisi vaega ua tineia (tetele i totonu) o le a ta'e pe a pikiina.O nei vaega e matua'i fa'afefeteina ma ta'e e aunoa ma se fa'alavelave i fafo, lea e le mafai ona toe fa'aaogaina e toe fa'afoisia ai le malosi muamua e ala i le dehydrogenation.

O le maualuga o le malosi o meafaitino, o le sili atu lea o le faʻaogaina o le hydrogen embrittlement.Ole manatu fa'avae lea e tatau ona fa'amanino e le au tekinisia togafitiga ile fa'apipi'iina ole fa'asologa ole fa'asologa ole eletise.O u'amea e iai le malosi fa'amalosi σb>105kg/mm2 e mana'omia e tulaga fa'ava-o-malo e tatau ona fa'atatau i le fa'amamafaina muamua ma le fa'amama fa'ama'i fa'ama'i.E mana'omia e le kamupani vaalele a Farani ni togafitiga fa'ama'i fa'amasani mo vaega u'amea e maua ai le malosi σs>90kg/mm2.

Ona o le fetaui lelei i le va o le uʻamea malosi ma le maaa, e sili atu le faʻaogaina ma faigofie e faʻamasino ai le faʻaogaina o le hydrogen embrittlement lagona o mea e ala i le faigata nai lo le malosi.Ona o se oloa atoatoa ata tusi ma machining faagasologa e tatau ona faailoga i le maaa uamea.I le electroplating, na matou iloa ai o le maaa o le uamea i le HRC38 na amata ona faʻaalia le lamatiaga o le gau o le hydrogen.Mo vaega e maualuga atu i le HRC43, e tatau ona iloiloina le dehydrogenation pe a uma ona faʻapipiʻi.A oʻo i le maaa e tusa ma le HRC60, e tatau ona faʻatinoina togafitiga faʻamaʻi i le taimi lava e maeʻa ai togafitiga, a leai o le a taʻe vaega uamea i totonu o ni nai itula.
