Manje imikhiqizo eminingi yezimboni izokwenziwa ngezinto zezintambo zensimbi engagqwali.Ukuze kutholakale insimbi engagqwali engelona iqiniso futhi engaphansi, izinyathelo nezindlela ezithile zingathathwa.Kodwa amakhasimende amaningi awazi ukuthi iyiphi indlela yokuhlonza, akubhalele lezi zindlela zokuhlonza ezilandelayo.
Indlela yokuhlola kazibuthe ingumehluko ovamile ovamile phakathi kwensimbi engagqwali ye-austenitic kanye nensimbi engagqwali ye-ferritic indlela elula, insimbi engagqwali ye-austenitic iyinsimbi kazibuthe engalungile, kodwa ngemva kokucubungula okubandayo ngaphansi kwengcindezi enkulu izoba nozibuthe omncane;Kodwa insimbi ye-chrome ehlanzekile nensimbi ephansi ye-alloy iyinsimbi enamandla kazibuthe.
Isici esimangalisayo sentambo yensimbi engagqwali ukumelana nokugqwala kwayo okungokwemvelo ku-nitric acid egxilile kanye ne-nitric acid ehlanjululwe, okwenza kube lula ukuhlukaniswa kwezinye izinsimbi noma ama-alloys amaningi.Kodwa insimbi ephezulu ye-carbon 420 kanye ne-440 ekuhlolweni kwephoyinti le-nitric acid igqwalile kancane, insimbi engeyona insimbi ehlangene ne-nitric acid egxilile igqwala ngokushesha, futhi i-nitric acid ehlanjululwe inokugqwala okuqinile ku-carbon steel.
Ukuhlola iphuzu le-Copper sulfate kuyindlela elula yokuhlukanisa ngokushesha i-carbon steel evamile kanye nazo zonke izinhlobo zentambo yensimbi engagqwali.Ukuhlushwa kwe-copper sulfate solution esetshenziswayo kungu-5% -10%.Ngaphambi kokuhlolwa kwephuzu, indawo yokuhlola kufanele isuswe ngokuphelele emafutheni noma kwezinye izinto ezingcolile, futhi indawo encane kufanele ipholishwe ngomshini wokugaya noma indwangu yokugaya ethambile, bese uketshezi lokuhlola lwehlela endaweni yokugaya.I-carbon steel evamile noma insimbi emizuzwaneni embalwa izokwakha ungqimba lwethusi lensimbi yangaphandle, futhi ingaphezulu lensimbi engagqwali alikhiqizi imvula yethusi noma libonise umbala wethusi.
