Answer
Hydrogen Embrittlement (HE) wata hanya ce ta gazawa ta bala'i inda hydrogen atomic ya bazu zuwa cikin babban ƙarfin martensitic lattice na carbon karfe (SAE 1070-1090) bazara yayin aikin lantarki. Lokacin da aka damu da bazara, hydrogen yana ƙaura zuwa wuraren da ke da yawan damuwa, yana haifar da fashewar intergranular. Don rage wannan, ma'auni na masana'antu kamar ASTM B633 suna buƙatar sake zagayowar 'yin burodi' nan take. Dole ne a sanya maɓuɓɓugan ruwa a cikin tanda a $375 ^\circ F$ ($ 190 ^\circ C $) na akalla sa'o'i 4 zuwa 24 a cikin sa'o'i 1 zuwa 4 na plating. Wannan gasa 'de-embrittlement' yana bawa hydrogen damar yaduwa daga cikin kayan. Don ƙayyadaddun abubuwan aminci na kera motoci masu mahimmancin manufa, ana zaɓin gyare-gyaren inji ko madadin ƙarfe don kawar da haɗarin HE gaba ɗaya.
