Ni izihe ngaruka zihariye ziterwa na hydrogène mu byuma bya karuboni nyinshi ziva mu mashanyarazi nyuma y’amashanyarazi, kandi ukwezi kwa 'Baking' bisobanurwa gute?

Ibyuma bya karubone nyinshi nka SAE 1070 kugeza 1090 hamwe nuburemere burenze HRC 40 birashoboka cyane kwanduza Hydrogen Embrittlement (HE). Mugihe cyo gutoranya aside cyangwa amashanyarazi, hydrogène ya atome ikwirakwira mu cyuma kandi ikarundanya ku mbibi z’ibinyampeke hamwe n’ibitera imbaraga (impinga y’umuraba). Munsi yumutwaro wa axial, atome ya hydrogen itera kuvunika. Kugira ngo ibi bigabanuke, uburyo bwo guteka ni itegeko mugihe cyamasaha 4 uhereye kumasahani. Ukurikije ASTM B633 cyangwa ibipimo bisa, amasoko agomba gutekwa kuri 190 ° C kugeza kuri 220 ° C mumasaha 8 kugeza 24 bitewe nuburebure bwigice nurwego rwimbaraga. Kunanirwa guteka ibisubizo muburyo butunguranye, kuvunika cyane mugihe cyambere cyo kwikuramo cyangwa mugihe gihamye.
