Hydrogen nwere ike ime na Symonnia Syntheria, mmeghachi omume hydrogen Hydrogenation na mmanụ na-edozi. Carbon steel adịghị mma maka iji ihe nrụnye hydrogen dị elu karịa 232 Celsius. Hydrogen nwere ike iso na nchara ma meghachi omume na ígwè ígwè na ala ma ọ bụ na mpaghara ọka pearlitic iji mechaa metlane. Methane (gas) enweghị ike ịgbasa na mpụga nke ígwè ma na-anakọta, na-emepụta ọcha tụrụ na cracks ma ọ bụ nke ndị a na igwe.
Iji gbochie mmepụta nke methane, a ga-etinye carburation site na carbis, a ga-agbakwunye na chromium na Chromium, vanadium, titanium ma ọ bụ olulu. Edeela ya nke na-abawanye na Cromium ọdịnaya ikike ikikere dị elu na nrụgide nke ihu igwe iji mepụta carbom carbom na steepụ ndị a, na ọ kwụsie ike megide hydrogen. Chromium steels na steel na-acha nkịtị nwere ihe karịrị 12% Chromium na-eguzogide na ngwa niile a na-eji mara (okpomọkụ karịa 593 Celsius C).
Ọtụtụ ọlaNa alloys anaghị emeghachi omume na nitrogen motrogen na oke okpomọkụ, mana nitrogen na-emeghachi omume ọtụtụ ndị na-ekwu. na-abanye n'ime ya n'ime steel iji mepụta akwa mkpuchi nitride. Iron, Alumin, Titanium, Chromium na ihe ndị ọzọ ịba ọcha na mmeghachi omume ndị a. Isi mmalite nke atomic nitrogen bụ ihe ndozi nke Ammonia. Amon Romonia na-eme na ndị ntụgharị amonia, ndị Amọnmoria na-emepụta ọkụ na ọkụ nitroị na-arụ ọrụ na 371 Celsius C, otu ikukushon ~ 10.5KG / mm².
N'ime ikuku ndị a, cromium carbide na-egosi na chromium dị ala. Enwere ike ịgbanye ya na nitrogen nke atom ma mepụta chrom na crowride nke carbon na hydrogen iji mepụta methane, nke a kpọtụrụ aha n'elu, nke nwere ike imepụta ntụpọ ọcha na cracks, ma ọ bụ otu n'ime ha. Agbanyeghị, na chromium dị n'elu 12%, ụgbọ ala ndị a na-akwụ ụgwọ karịa chromium na-adịghị ike karịa Chromium nitride, yabụ a na-ejikarị ya ugbu a na gburugburu okpomọkụ dị elu na-ekpo ọkụ na amonia.
Ọnọdụ nke igwe anaghị agba nchara na Ammonia site na okpomọkụ, nrụgide, ịta gas na-adọrọ adọrọ na ọdịnaya chricel.
