Ukucaciswa kweMathiriyeli yeMetal yeSixhobo soMbane esibuNgqibo

Umba ophambili emawuqwalaselwe kwimathiriyeli yesinyithi kwisixhobo sombane esingaqhubi luqhushumbo kukuthambekela kwabo ukutshisa imixube yerhasi yomoya oqhumayo ngokusebenzisa iintlantsi zoomatshini.. Uphando lubonise ukuba ukubunjwa kwezi zinyithi kudlala indima enkulu kumandla azo wokutshisa. Ukuthintela ukwenzeka kwe-spark spark evuthayo kwiindawo ezivaliweyo zetsimbi, Izithintelo ezithile ezingundoqo ziyagunyaziswa. Imigangatho ye qhuma iindawo ezingqongileyo – IiMfuno zesiXhobo ngokubanzi – cacisa oku kulandelayo:

Iklasi I

Ekuveliseni RPL kwinqanaba MA okanye Mb izixhobo zombane ezingaqhushumba, ukwakheka kwealuminiyam, imagnesium, titanium, kunye ne-zirconium kwizinto ezivaliweyo kufuneka zingadluli 15% ngobunzima, kunye nepesenti yobunzima obudibeneyo be-titanium, imagnesium, kwaye i-zirconium mayingagqithi 7.5%.

Udidi II

Kudidi lwesibini lwemveliso yezixhobo zombane ezingaqhushumbayo, ipesenti yobunzima obupheleleyo bezinto ezibalulekileyo kwizinto ezivalelekileyo ziyahluka ngokusekelwe kwinqanaba lokukhusela: Kwizixhobo ze-EPLGa, umxholo opheleleyo we-aluminiyam, imagnesium, titanium, kwaye i-zirconium mayingadluli 10%, kunye ne-magnesium, titanium, kunye ne-zirconium engagqithiyo 7.5% zizonke; Yezixhobo zeEPLGb, umxholo we-magnesium kunye ne-titanium kufuneka ungadluli 7.5%; Kwimeko yezixhobo ze-EPLGc, ngaphandle kwabalandeli, amagquma fan, kunye nemingxuma yokungena umoya idibana nemigangatho ye-EPLGb, akukho mfuneko ezongezelelweyo ezithile.

Udidi III

Kwimveliso yoMgangatho we-III izixhobo zombane ezingaqhushumba, ipesenti efunekayo yobunzima bezinto ezifanelekileyo kwizinto ezivalelekileyo nazo ziyahluka kunye nenqanaba lokukhusela: Yezixhobo zeEPDa, Umxholo we-magnesium kunye ne-titanium akufanele udlule 7.5%; Ngezixhobo zeEPLDb, umlinganiselo ofanayo uyasebenza; Yezixhobo ze-EPLDc, ngaphandle kwabalandeli, amagquma fan, kunye nemingxunya yokungenisa umoya ebambelela kwiikhrayitheriya ze-EPLDb, azikho ezinye iimfuneko ezizodwa.
