Imibhobho ye-aluminiyam ye-T6 isetyenziswa ngokubanzi kwizicelo ezahlukeneyo zemizi-mveliso ngenxa yamandla ayo angaqhelekanga, alula, kunye nokumelana nomhlwa. Ukugcina umgangatho wale mibhobho kubaluleke kakhulu ukuqinisekisa ukuthembeka kunye nokuqina. Eli nqaku livavanya imilinganiselo yokulawula umgangatho obanzi oqeshwe kwi-T6 yokwenziwa kombhobho we-aluminium, equka iinkalo ezininzi ukusuka ekuhlolweni kwezinto eziluhlaza ukuya kuvavanyo lokugqibela lwemveliso.
Umgangatho wemibhobho ye-aluminium ye-T6 idibaniswe ngokugqithiseleyo nokucoceka kunye nokubunjwa kwe-alloy aluminium eluhlaza. Phambi kokwenziwa kokwenziwa, imathiriyeli ekrwada ihlolwa ngokucokisekileyo ukuze kuqinisekiswe ukuthotyelwa kwayo nemigangatho emiselweyo. Iindlela zokuhlalutya iikhemikhali, ezifana ne-optical emission spectroscopy (OES), zisetyenziselwa ukumisela ukwakhiwa kwe-elemental echanekileyo kunye nokuqinisekisa ukuba i-aluminiyam ihlangabezana neenkcukacha ze-alloy ezichaziweyo. Ukuhlola okubonwayo kwakhona kuphonononga imathiriyeli ekrwada kuzo naziphi na iziphene zomhlaba okanye ukungafezeki.
I-Extrusion yinkqubo ebalulekileyo kwi-T6 yokwenziwa kombhobho we-aluminium. Iiparamitha ze-extrusion, kubandakanywa ubushushu, isantya sokukhupha, kunye noyilo lwezixhobo, zilawulwa ngokucokisekileyo ukuze kuphunyezwe ubungakanani bombhobho obufunwayo, ukunyamezela, kunye neempawu zoomatshini. Ukulinganisa rhoqo kunye nokugcinwa kwezixhobo ze-extrusion zenziwa ukuze kuqinisekiswe ukusebenza okufanayo kunye nokufanelekileyo. Iindlela zokuvavanya ezingonakalisi, ezinje ngovavanyo lwe-ultrasonic, zisetyenziselwa ukuhlola imibhobho ekhutshiweyo kuzo naziphi na iimpazamo zangaphakathi okanye ukungaqhubeki.
I-T6 unyango lokushisa lubandakanya ukulandelelana okuthe ngqo kokuguga kunye neenkqubo zokucima ukunyusa amandla omatshini kunye nobunzima beepayipi ze-aluminium. Ukulawulwa ngokuchanekileyo kwexesha kunye nokushisa ngexesha lokunyanga ukushisa kubalulekile ukufezekisa i-microstructure efunwayo kunye neempawu zomatshini. Iinkqubo zokujonga ubushushu obuphezulu kunye nabagcini bedatha baqeshwa ukuqinisekisa ukuba iiparamitha zonyango lobushushu zithotyelwa ngokungqongqo. Uvavanyo lobunzima kunye novavanyo lwe-tensile lwenziwa ukuze kuqinisekiswe ukusebenza kwenkqubo yonyango lokushisa.
Ukuchaneka komgangatho kunye nomgangatho womphezulu kubalulekile ekusebenzeni okufanelekileyo kunye nobuhle bemibhobho ye-aluminiyam ye-T6. Imilinganiselo yobukhulu ithathwa ngobuchule kumanqanaba ahlukeneyo enkqubo yokwenziwa kusetyenziswa izixhobo zokulinganisa ezichanekileyo, ezinje ngoomatshini bokulinganisa abalungelelanisiweyo (ii-CMM) kunye nezikena zelaser. Ukuhlolwa komphezulu kuvavanya imibhobho malunga noburhabaxa bomphezulu, imikrwelo, kunye nezinye iziphene. Olu hlolo luqinisekisa ukuba imibhobho ihlangabezana nokunyamezela okuxeliweyo kunye neemfuno zokugqiba umgangatho.
Uvavanyo olunzulu lweekhemikhali lwenziwa kwimibhobho ye-aluminium ye-T6 egqityiweyo ukuqinisekisa ukubunjwa kweekhemikhali kunye nokuqinisekisa ukuthotyelwa kwemigangatho yoshishino. Uvavanyo lomatshini, kubandakanywa uvavanyo lokuqina, uvavanyo lwamandla esivuno, kunye novavanyo lokuqina, lwenziwa ukuvavanya iimpawu zomatshini zemibhobho. Ezi mvavanyo zivavanya amandla, ukudumba, kunye nokuqina kwemibhobho kwaye ziqinisekisa ukuba ziyahlangabezana nemilinganiselo yokusebenza efunekayo.
Uvavanyo olungonakalisi (NDT) ludlala indima ebalulekileyo ekuchongeni iziphene okanye ukungafezeki ngaphakathi kwimibhobho ye-aluminium ye-T6 ngaphandle kokuphazamisa ingqibelelo yabo. Uvavanyo lwangoku lwe-Eddy, uvavanyo lwe-ultrasonic, kunye novavanyo lwe-radiographic ziqhele ukusetyenzwa ukukhangela iziphene ezingaphezulu kunye ne-subsurface, ukubandakanywa, kunye nokuqhekeka. Ezi zixhobo zibonelela ngengqiqo ebalulekileyo kwisakhiwo sangaphakathi semibhobho, ukuqinisekisa ukuvakala kwabo kunye nokuthembeka.
Inkqubo yolawulo lomgangatho osebenzayo (QMS) ibalulekile ukugcina umgangatho ongaguqukiyo kuyo yonke inkqubo yokuvelisa. I-QMS ichaza uxanduva olucacileyo, iinkqubo, kunye neemfuno zamaxwebhu kuzo zonke iinkalo zemveliso. Uphicotho-zincwadi lwarhoqo lwangaphakathi kunye neziqinisekiso zangaphandle, ezifana ne-ISO 9001, zibonelela ngokuqinisekiswa okuzimeleyo kokusebenza nokuthotyelwa kwe-QMS.
Amanyathelo okulawula umgangatho kwi-T6 yokwenziwa kombhobho we-aluminiyam ayimfuneko ekuqinisekiseni ukuthembeka, ukuqina, kunye nokusebenza kwala macandelo abalulekileyo. Ukusuka kuhlolo olucokisekileyo lwemathiriyeli ekrwada ukuya kuvavanyo olungqongqo lwemveliso yokugqibela, inyathelo ngalinye lenkqubo yokwenziwa kwemveliso lihlolwa ngononophelo kwaye lilawulwe. La manyathelo abonelela ngesiqinisekiso sokuba imibhobho ye-aluminiyam ye-T6 ihlangabezana neemfuno ezingqongqo zezicelo ezahlukeneyo zemizi-mveliso, igalelo kukhuseleko lulonke kunye nokusebenza kakuhle kweenkqubo ezixhomekeke kuzo.
