304 ityhubhu yentsimbi etyebileyo enodongaUmahluko we weld ngaphambi nasemva konyango lomphezulu kunye nokulungiswa kubonisa ukuba: le ndlela inokususa isikali kunye nombala womsindo.

Xa abantu bephakamisa i-304 yentsimbi eshinyeneyo enodonga olungqindilili lwetyhubhu yomphezulu we-oxide yesiqulatho sechromium oxide, ulwakhiwo lomaleko we-oxide emva kokulungiswa, unokuphucula kakhulu ukusebenza komhlwa kwe-304 yentsimbi eshinyeneyo enodonga lomphezulu wetyhubhu.Ngeendlela zonyango lwekhemikhali ukuphumeza ityhubhu engama-304 yentsimbi etyebileyo enodonga olungqingqwa ukuze kuphuculwe ukuxhathisa umhlwa kumphezulu ngamanyathelo amabini.Nkqu 304 intsimbi etyebileyo-ebiyelwe ityhubhu edityanisiweyo ngale ndlela inokusetyenziselwa ukuphucula ukuxhathisa kwayo ekudlekeni.

Xa i-304 yentsimbi eshinyeneyo enodonga olungqingqwa ukumelana nomhlwa ingonelanga, ingcali yonyango lomphezulu inkampani yasePoligrat Munich iphuhlise iteknoloji yePolinox Protec TC inokukunceda ukusombulula le ngxaki.Esi sixhobo somatshini kunye nababoneleli beekhemikhali baphuhlise itekhnoloji yokuphucula i-nickel, i-molybdenum kunye ne-chromium austenitic alloy material, ngaloo ndlela iphucula ukuxhathisa ukubola kwe-304 yentsimbi etyebileyo enodonga olungqingqwa.Ngamanyathelo amabini kunokwandiswa 304 intsimbi eshinyeneyo-engqingqwa ityhubhu umphezulu oxide umaleko ukuxhathisa umhlwa.

Inyathelo lokuqala ekusetyenzisweni kwesisombululo samanzi esisekwe kwi-organic engama-304 yentsimbi etyebileyo enodonga lomphezulu wetyhubhu iphathwa ngomphezulu.Olu nyango lomphezulu luya kuhlala 3 ~ 5h.Ngeli xesha, susa umaleko oxide ukusuka kumphezulu inxalenye yentsimbi, kunye nokunciphisa intsimbi, chromium kunye nentsimbi ratio yanda ukusuka 6% ukuya 8%, ukuba indima esebenzayo ekuphuculeni ukumelana umhlwa iye.

Isinyathelo sesibini sokwandisa ubume bomgangatho we-oxide layer.Oku kuphucula ngakumbi ukuxhathisa ukubola komgangatho we-oxide ongaphezulu.Ukuchaphazela isakhiwo somgangatho we-oxide ye-face yinyathelo lonyango lobushushu: ngokohlobo lwe-alloy kunye nobushushu bonyango lwe-crystal lattice yento emoyeni kwi-140.℃~ 200℃kwi.
