Izinyathelo Zokulawula Ikhwalithi
Cishe yonke insimbi igqwala ngaphansi kwezimo ezithile. Lapho ama-athomu ensimbi efakwa i-oxidized uketshezi, ukugqwala kuzokwenzeka, okuholela ekulahlekeni kwezinto ezibonakalayo endaweni yensimbi. Lokhu kunciphisa ukushuba kwezingxenye ezifanaama-ferrulesfuthi kubenza bathambekele kakhulu ekuhlulekeni kwemishini. Izinhlobo eziningi zokugqwala zingenzeka, futhi uhlobo ngalunye lokugqwala lubeka usongo, ngakho-ke kubalulekile ukuhlola impahla engcono kakhulu yohlelo lwakho lokusebenza.
Nakuba ukwakheka kwamakhemikhali kwezinto kungathinta ukumelana nokugqwala, enye yezinto ezibaluleke kakhulu zokunciphisa ukwehluleka okubangelwa ukukhubazeka kwempahla yikhwalithi iyonke yezinto ezisetshenziswayo. Kusukela ekuhlonzweni kwebha kuya ekuhlolweni kokugcina kwezingxenye, ikhwalithi kufanele ibe yingxenye ebalulekile yazo zonke izixhumanisi.
Ukulawulwa Kwenqubo Yezinto Ezibalulekile Nokuhlola
Indlela engcono kakhulu yokuvimbela izinkinga ukuzithola ngaphambi kokuba zenzeke. Enye indlela iwukuqinisekisa ukuthi umphakeli uthatha izinyathelo eziqinile zokulawula izinga ukuvimbela ukugqwala. Lokho kuqala ekulawuleni inqubo kanye nokuhlolwa kwesitoko sebha. Ingahlolwa ngezindlela eziningi, kusukela ekuqinisekiseni ukuthi impahla ayinakho noma yikuphi ukukhubazeka okungaphezulu kuya ekuhloleni okukhethekile ukuze kutholwe ukuzwela kwento ekugqwaleni.
Enye indlela abahlinzeki abangakusiza ngayo ukuthi uqinisekise ukufaneleka kwento ethile ukuhlola okuqukethwe kwezinto ezithile ekubunjweni kwento. Ngokumelana nokugqwala, amandla, ukushisela kanye ne-ductility, indawo yokuqala ukukhulisa ukwakheka kwamakhemikhali we-alloy. Isibonelo, okuqukethwe kwe-nickel (Ni) ne-chromium (CR) ku-316 insimbi engagqwali kuphakeme kunezidingo ezincane ezicaciswe ekucacisweni okujwayelekile kwe-ASTM International (ASTM), okwenza okokusebenza kube nokumelana nokugqwala okungcono.
Kuhlelo Lokukhiqiza
Ngokufanelekile, umphakeli kufanele ahlole izingxenye kuzo zonke izinyathelo zenqubo yokukhiqiza. Isinyathelo sokuqala siwukuqinisekisa ukuthi imiyalelo yokukhiqiza efanele iyalandelwa. Ngemuva kwezingxenye zokukhiqiza, ukuhlolwa okwengeziwe kufanele kuqinisekise ukuthi izingxenye zenziwe ngendlela efanele futhi azikho izinkinga ezibonakalayo noma ezinye izinkinga ezingase zithiye ukusebenza. Ukuhlola okwengeziwe kufanele kuqinisekise ukuthi izingxenye zisebenza njengoba kulindelekile futhi zivalwe kahle.
