Ukuphoswa kwe-aluminium alloy: izisombululo zonyango lomphezulu zobungcali
inkcazo1
Isishwankathelo sonyango lomphezulu we-aluminium alloy
Unyango lomphezulu we-aluminium alloy kukutshintsha iipropati, imo, ukwakheka kweekhemikhali kunye nesakhiwo se-microstructure somphezulu we-aluminium alloy castings ngeendlela ezibonakalayo okanye zeekhemikhali ukuze kufunyanwe imeko yomphezulu ehlangabezana neemfuno zokusetyenziswa. Injongo yayo kukuphucula ukumelana nokugqwala, ukumelana nokuguguleka, ukuhombisa kwe-castings, ukuphucula ukuqhuba, ukuwelda kunye nezinye iipropati, kunye nokwandisa ubomi benkonzo yeemveliso.
Unyango lwe-anodizing
I-Anodizing kukubeka i-aluminium alloy kwi-electrolyte ehambelanayo, ukuyenza i-anode, kwaye yenze ifilimu ye-oxide exineneyo kumphezulu we-aluminium nge-electrolysis. Le filimu ye-oxide inokumelana okuhle nokugqwala kwaye inokuthintela ngempumelelo i-oxidation kunye nokugqwala kwe-aluminium alloy kwiindawo ezinzima. Ukongeza, ubukhulu, ubunzima kunye nombala wefilimu ye-oxide zinokulungiswa ngokulawula ukwakheka kwe-electrolyte kunye neeparamitha zenkqubo. Umzekelo, ifilimu ye-anodized efunyenwe kwi-sulfuric acid electrolyte inokumelana okuphezulu kokugqwala kunye nokutsalwa okuhle, kwaye inokufakwa imibala eyahlukeneyo. Isetyenziswa kakhulu kulwakhiwo, iimoto, izixhobo zasekhaya nakwamanye amashishini ukuphucula umgangatho wokubonakala kunye nokusebenza okukhuselekileyo kweemveliso.
Unyango lokuguqulwa kweekhemikhali
Unyango lokuguqulwa kweekhemikhali kukwenza ifilimu yokuguqulwa kweekhemikhali kumphezulu we-aluminium alloy. Ezona ziqhelekileyo kunyango lwe-chromate kunye nonyango lwe-phosphate. Ifilimu yokudlulisa amandla eyenziwe ngonyango lwe-chromate inokumelana okuhle kokugqwala kwaye inokuthintela ngempumelelo ukudibana phakathi kwe-aluminium alloy kunye ne-corrosive medium. Ihlala isetyenziselwa ii-castings ezineemfuno eziphezulu zokuxhathisa ukugqwala. Unyango lwe-phosphate ikakhulu lwenza ifilimu ye-phosphate kumphezulu wee-castings, engenakukwazi nje ukuphucula ukumelana nokugqwala kwee-castings, kodwa ikwaphucula ukusebenza kwayo kokugquma, ukuze ukugquma okulandelayo kunye nomphezulu wokugquma kudityaniswe ngakumbi, kwaye ukunamathela kunye nefuthe lokukhusela lokugquma kuphuculwe. Isetyenziswa kakhulu kwi-aerospace, ezothutho nakwezinye iindawo.
Unyango lwe-electroplating
I-Electroplating kukufaka umaleko wesinyithi okanye i-alloy phezu komphezulu we-aluminium alloy ngomgaqo we-electrolysis ukuze kufunyanwe iimpawu zomphezulu ezifunekayo. Kwi-aluminium alloy castings, ngokusebenzisa iinkqubo ezifanelekileyo zonyango lwangaphambi konyango kunye ne-electroplating, ukufakwa kweengubo ezahlukeneyo zesinyithi kunokufezekiswa, njenge-zinc plating, i-nickel plating, i-chromium plating, njl. I-Galvanizing inokuphucula ukumelana nokugqwala kwe-castings kwaye isetyenziselwa ukwenza iindawo kwiindawo ezifumileyo; i-nickel plating inokubonelela ngokumelana nokugqwala okuhle kunye nokumelana nobushushu, kwaye ifanelekile kwiindawo ezifuna ubunzima obuphezulu kunye nokumelana nokugqwala; i-chrome plating inobunzima obuhle kunye nokukhazimla, kwaye idla ngokusetyenziselwa iimveliso ezineemfuno eziphezulu zokuhombisa, ezifana namavili eemoto, izixhobo zegumbi lokuhlambela, njl., ukuze umphezulu ungabi nembonakalo entle kuphela, kodwa ube nobomi obude benkonzo.
Ukuqhuma kwesanti
Ukuqhumisa isanti kukusetyenziswa komoya ohamba ngesantya esiphezulu ukutshiza amasuntswana arhabaxa phezu komphezulu we-aluminium alloy castings, kunye nokususa ukungcola komphezulu, amabala eoyile, izikali ze-oxide, njl. ngokusebenzisa impembelelo ye-abrasives, ngelixa kwakheka inqanaba elithile loburhabaxa kumphezulu we-cast. Olu burhabaxa lunokwandisa indawo yoqhagamshelwano phakathi kwengubo kunye nomphezulu we-cast, luphucule ukunamathela kwengubo, kwaye lubonelele ngesiseko esihle sokufakwa komphezulu okulandelayo okanye unyango lokukhusela. Umzekelo, ngaphambi kokugquma kwezinye iindawo zoshishino, ukuqhumisa isanti kunokuphucula ngempumelelo ukunamathela kwengubo, ukuze iindawo ezipeyintiweyo zibe nokumelana okungcono kwemozulu kunye nokusebenza kokukhusela, zandise ubomi bazo benkonzo, kwaye umphezulu we-cast emva kwe-sandblasting ubonise isiphumo esifanayo se-matte, esinokuphucula nomgangatho wembonakalo yemveliso ukuya kwinqanaba elithile.
Unyango lokuDaya nokutywina
Emva kokugqiba ezinye zeenkqubo zonyango lomphezulu ezingasentla, ezifana nonyango lwe-anodizing kunye nokuguqulwa kweekhemikhali, ukudaya kunye nonyango lokutywina kudla ngokwenziwa ukuphucula ngakumbi isiphumo sombala kunye nokusebenza okukhuselekileyo komphezulu wokuphosa. Ukudaya kungenza umphezulu wokuphosa ube nemibala eyahlukeneyo eqaqambileyo, njengobomvu, luhlaza okwesibhakabhaka, luhlaza, njl.njl., ngokweemfuno zabathengi kunye neemfuno zoyilo lwemveliso. Unyango lokutywina kukubeka i-casting elungisiweyo kulwelo olukhethekileyo lokutywina ukuze kuzaliswe kwaye kutywinwe ii-micropores kumphezulu ukuthintela ukungena kwemidiya yangaphandle ebolayo, kunye nokuthintela idayi ukuba ingafi kwi-micropores, okwenza umbala ube qinile kwaye uhlale ixesha elide, ukuqinisekisa ukuba i-casting igcina imbonakalo entle kunye nokusebenza kakuhle ngexesha lokusetyenziswa ixesha elide.
