Answer
Hydrogen Embrittlement (HE) ni uburyo bwo kunanirwa gukabije aho hydrogène ya atome ikwirakwira mu mashanyarazi akomeye ya martensitike y’icyuma cya karubone (SAE 1070-1090) mu gihe cy’amashanyarazi. Iyo amasoko ashimangiwe, hydrogène yimukira mu turere twibanda cyane, bigatuma habaho gucikamo ibice. Kugira ngo ibyo bigabanuke, amahame yinganda nka ASTM B633 akenera 'guteka' ako kanya. Amasoko agomba gushyirwa mu ziko $ 375 ^ \ kuzenguruka F $ ($ 190 ^ \ kuzenguruka C $) byibuze amasaha 4 kugeza 24 mugihe cyamasaha 1 kugeza 4. Iyi 'de-embrittlement' iteka bituma hydrogène ikwirakwira mubintu. Kubikoresho byingenzi byumutekano wibinyabiziga, isahani yubukanishi cyangwa ibyuma bidafite ibyuma bisimburwa akenshi kugirango bikureho ibyago bya HE burundu.
