Izinyathelo Zokuvimbela I-Intercrystalline Corrosion
Izinyathelo zokuvimbela ukugqwala kwe-intercrystalline
I-Intercrystalline corrosion iwuhlobo olubi lokwehluleka kwempahla, ngokuvamile okuholela ekwehleni kokusebenza kwemishini kanye nezingozi zokuphepha. Ukuze uvimbele ukuvela kwe-intercrystalline corrosion, uchungechunge lwezinyathelo zokuvimbela eziphumelelayo ziyadingeka.
Okokuqala, ukukhethwa kwezinto ezimelana nokugqwala kwe-intercrystal kuyisihluthulelo. Lapho ukhetha izinto zokwakha, ukumelana kwazo nokugqwala endaweni ethile kufanele kucatshangelwe ngokugcwele. Isibonelo, okokusebenza okusetshenziselwa imidiya eqinile yokugqwala, izinto ze-alloy ezinokumelana nokugqwala okuqinile, njengensimbi engagqwali, i-alloy-based alloy, kufanele kukhethwe.
Okwesibili, ukulawula inqubo yokucubungula izinto futhi kuyisinyathelo esibalulekile sokuvimbela ukugqwala kwe-intercrystalline. Enqubweni yokwelashwa kokushisa kanye nokushiselwa kwezinto, imingcele yenqubo kufanele ilawulwe ngokuqinile ukuze kugwenywe ukucindezeleka okusala ngokweqile kanye nesenzakalo sokuhlanjululwa komngcele wokusanhlamvu. Ngaphezu kwalokho, ukwelashwa kwendawo efanele yezinto ezibonakalayo, njengokufafaza i-anticorrosive coating, i-electroplating, njll., kungathuthukisa ngempumelelo ukumelana nokugqwala kwayo.
Ngaphezu kwalokho, ukulawulwa kwezici zemvelo nakho kuwukuvimbela ukugqwala kwe-intercrystalline. Ekusetshenzisweni kwemishini, ukugqwala kwezinto eziyingozi phakathi nendawo kufanele kugwenywe. Isibonelo, ezintweni ezisetshenziswa emkhakheni wamakhemikhali, ingaphakathi lempahla kufanele ihlanzwe njalo ukuze kuvinjelwe ukunqwabelana kwezinto ezigqwalisayo. Ngesikhathi esifanayo, ngemishini esetshenziswa ekushiseni okuphezulu, umswakama ophezulu kanye nezinye imvelo enokhahlo, izinyathelo zokuzivikela ezihambisanayo kufanele zithathwe, njengokuqinisa ukubekwa uphawu kwemishini, ukusebenzisa ama-preservatives, njll.
Okokugcina, ukuhlolwa okuvamile nokuhlolwa kokumelana nokugqwala kwezinto kuyindlela ebalulekile yokuvimbela ukugqwala kwe-intercrystalline. Ukugqwala kwe-Intercrystalline kungagwenywa ngokuthola isimo sokugqwala kwempahla njalo nokuthola nokwelapha izinkinga ezingaba khona zokugqwala kusenesikhathi. Ngesikhathi esifanayo, ukuhlolwa kokumelana nokugqwala kwezinto kunganikeza isisekelo sesayensi sokukhethwa kwezinto ezibonakalayo kanye nenqubo yokucubungula imishini.
Ukufingqa, ukuvimbela ukugqwala kwe-intercrystalline kudinga kusukela ekukhethweni kwezinto ezibonakalayo, ukulawulwa kwenqubo yokucubungula, ukulawulwa kwezinto ezizungezile kanye nokutholwa okuvamile, kanye nokuthatha izinyathelo ezibanzi zokuqinisekisa ukuthi okokusebenza kungasebenza ngokuzinza nangokuthembekile endaweni enokhahlo.
