Amanyathelo othintelo loKutya kwe-Intercrystalline
Amanyathelo othintelo kwi-intercrystalline corrosion
I-Intercrystalline corrosion yindlela enzulu yokusilela kwezinto, ehlala ikhokelela ekunciphiseni ukusebenza kwezixhobo kunye nemingcipheko yokhuseleko. Ukuze kuthintelwe ukwenzeka kwe-intercrystalline corrosion, uluhlu lwamanyathelo okukhusela asebenzayo afunekayo.
Okokuqala, ukukhethwa kwe-intercrystal corrosion resistant materials ngundoqo. Xa ukhetha izinto eziphathekayo, ukuxhathisa kwabo kwe-corrosion kwindawo ethile kufuneka kuqwalaselwe ngokupheleleyo. Ngokomzekelo, kwizixhobo ezisetyenziselwa imidiya ye-corrosion eyomeleleyo, izixhobo ze-alloy ezinokumelana ne-corrosion enamandla, njengensimbi engenasici, i-alloy-based alloy, kufuneka ikhethwe.
Okwesibini, ukulawula inkqubo yokulungiswa kwezinto kukwayindlela ebalulekileyo yokuthintela ukubola kwe-intercrystalline. Kwinkqubo yonyango lobushushu kunye ne-welding yezixhobo, iiparameters zenkqubo kufuneka zilawulwe ngokungqongqo ukuphepha ukuxinezeleka okushiyekileyo okugqithisileyo kunye nomda we-grain dilution phenomenon. Ukongezelela, unyango olufanelekileyo lomphezulu wezinto eziphathekayo, ezifana nokutshiza i-anticorrosive coating, i-electroplating, njl., inokuphucula ngokufanelekileyo ukuxhathisa ukubola.
Ukongeza, ukulawulwa kwezinto ezisingqongileyo kukuthintela ukubola kwe-intercrystalline. Ekusetyenzisweni kwezixhobo, ukubola kwezinto ezinobungozi phakathi kufuneka kugwenywe. Ngokomzekelo, izixhobo ezisetyenziswa kwintsimi yeekhemikhali, ingaphakathi lesixhobo kufuneka licocwe rhoqo ukuze kuthintelwe ukuqokelelana kwezinto ezitshabalalisayo. Ngexesha elifanayo, kwizixhobo ezisetyenziselwa ukushisa okuphezulu, umswakama ophezulu kunye nokunye okusingqongileyo okunzima, amanyathelo okukhusela ahambelanayo kufuneka athathwe, njengokuqinisa ukutywinwa kwezixhobo, ukusebenzisa izilondolozo, njl.
Ekugqibeleni, ukuvavanywa rhoqo kunye nokuvavanywa kokumelana nokubola kwezixhobo kuyindlela ebalulekileyo yokukhusela i-intercrystalline corrosion. I-Intercrystalline corrosion inokuphetshwa ngokufumanisa imeko ye-corrosion yesixhobo rhoqo kunye nokufumana kunye nokunyanga iingxaki ezinokuthi zenzeke ngexesha. Ngelo xesha, ukuvavanywa kokumelana nokubola kwezixhobo kunokubonelela ngesiseko senzululwazi sokukhethwa kwezinto kunye nenkqubo yokucubungula izixhobo.
Ukushwankathela, ukukhuselwa kwe-intercrystalline corrosion kufuna ukuqala ekukhethweni kwezinto eziphathekayo, ukulawulwa kwenkqubo yokucubungula, ukulawulwa kwezinto ezisingqongileyo kunye nokufumanisa rhoqo, kunye nokuthatha amanyathelo abanzi okuqinisekisa ukuba izixhobo ziyakwazi ukusebenza ngokuzinzileyo nangokuthembekileyo kwindawo enzima.
