Black annealed ngokuqinile ukukhuluma hhayi an annealing okuvamile, kodwa inqubo kanye annealing cishe.Ipayipi elimnyama lensimbiisikhumba siyi-black oxide!

I-Annealing: ukuthungatha ingxubevange yensimbi kushisiswe kuzinga lokushisa elifanele kanye nokugcina isikhathi esithile, bese kuba kancane inqubo yokwelapha ukushisa okupholisa kancane.Insimbi ene-Annealed yinhlangano ye-hypoeutectoid ferrite sheet pearlite;insimbi ye-eutectoid noma insimbi ye-eutectoid iyi-granular pearlite.Ngamafuphi inhlangano ye-annealing iseduze nenhlangano yesimo sokulingana.

Inhloso yokunciphisa

①ukunciphisa ubulukhuni bensimbi, i-ductility ethuthukisiwe, ukuze kube lula ukusika nokucubungula ukuguqulwa okubandayo.

②ukucolisiswa okusanhlamvu, ukuqeda ukuphonsa, ukubumba, ukukhubazeka kokushisela okubangelwa inhlangano, inhlangano kanye nokwakheka kwensimbi elinganayo, insimbi yokuthuthukisa ukusebenza noma ukwelashwa kokushisa okwalandela ukulungiswa kwezicubu.

③ukuqeda ukucindezeleka kwangaphakathi ensimbi ukuvimbela deformation nokuqhekeka.
