Iimveliso ze-aluminium alloy zisetyenziswa kakhulu kwiindawo ezininzi ngenxa yokusebenza kwazo okugqwesileyo. Nangona kunjalo, ukusebenza kwazo okugqwesileyo akunakuhlulwa kwiindidi ezahlukeneyo ze-aluminium alloy. Kwiminyaka yakutshanje, izongezo ze-aluminium alloy ziye zaba zizinto ezibalulekileyo zokuphucula ukusebenza kwe-aluminium alloys kunye nokuphucula isakhiwo sengqolowa.
Izongezo ze-aluminium alloyziikhemikhali ezongezwa kwisinyithi esinyibilikisiweyo ngexesha lenkqubo yokwenziwa. Ezi zongezo zisebenza imisebenzi eyahlukeneyo kwaye zinempembelelo enkulu kwimveliso yokugqibela. Indima yezongezo ezahlukeneyo iyahluka, umzekelo,izongezo ze-chromium, ezidlala indima ebalulekileyo ekongezeni i-chromium kwii-aluminium alloys kunye nokuphuculwa kwesakhiwo seenkozo, kunyeizongezo ze-manganese, nto leyo enokuchaphazela umxholo we-manganese kwiimveliso ze-aluminium alloy.
Kwi-zhelu, izongezo ze-aluminium alloy zikwaziwa njengezongezo ze-aluminium alloy ezingama-75%, oko kuthetha ukuba umxholo wezinto zeekhemikhali eziza kongezwa kwisongezo yi-75% kwaye okuseleyo yi-aluminium, edlala indima ebalulekileyo ekuphuculeni ukusebenza kunye nomgangatho weemveliso ze-aluminium alloy. Ukongeza, izongezo ze-aluminium alloy eziveliswa yi-zhelu zinemveliso engaphezulu kwe-95%. Oku kuphucula ukusetyenziswa kwezinto eziluhlaza, kunciphisa inkunkuma kwaye kwandisa ukusebenza kakuhle. Oku akuncedi nje kuphela abavelisi ukunciphisa iindleko, kodwa kukwakhuthaza uphuhliso oluzinzileyo lweshishini lonke.
Ukhuseleko lwendalo kunye nokungangcolisi kube yingxaki enkulu kuluntu. Kukho ulwazi olukhulayo ngokubaluleka kokukhusela okusingqongileyo kunye nesidingo seendlela zokuthatha amanyathelo anobuhlobo nokusingqongileyo kuzo zonke iimboni. Enye yeenzuzo eziphambili zokusebenzisa izongezo ze-aluminium alloy kukukhusela okusingqongileyo. Izinto ezinobungozi ziveliswa ngokungenakuphepheka kwimveliso yeekhemikhali. Izongezo ze-zhelu zigxila kukhuseleko lwendalo kunye nemveliso engenangcoliseko. Zithobela imigaqo engqongqo kwaye zinceda ekunciphiseni ukukhutshwa kwezinto ezingcolisayo eziyingozi ngexesha lenkqubo yemveliso.
Ezinye izongezo ze-aluminium alloy nazo zinefuthe elikhulu ekucoceni i-alloy. Ngokufaka izinto ezithile kwisinyithi esinyibilikisiweyo, ezi zongezo zinceda ekususeni ukungcola, ukuphucula ukufana kwe-alloy kunye nokuphucula iimpawu zayo zoomatshini. Umzekelo,ingot ye-magnesium, yongeza i-magnesium ingot injongo ephambili kukuphucula izalathisi zokusebenza kwe-aluminium alloy die casting, ngakumbi ukumelana nokugqwala. Ngokutsho kweengcali, i-aluminium kunye ne-magnesium alloy die casting ilula kwaye iqinile, iyakwazi ukumelana nokugqwala, kulula ukuyishibiliza kunye nonyango olungaphezulu, kukwenziwa kweenqwelo moya, iirokethi, iinqanawa ezikhawulezayo, izithuthi kunye nezinye izinto ezibalulekileyo. Ukongeza, indima yezongezo ze-aluminium alloy ayikokuphucula kuphela iipropati zoomatshini, ezi zongezo zikwaphucula ukusebenza kwe-alloy, okwenza kube lula ukuyicubungula nokuyiphatha. Zinceda ekunciphiseni iziphene ezenzeka ngexesha lokuphoswa nokubumba, ngaloo ndlela zonyusa isivuno kwaye zinciphise amazinga okulahlwa. Ukuphuculwa kokusebenza kwezi zongezo kunceda ukonga iindleko kwaye kuqinisekisa ukuveliswa kwezinto ezisemgangathweni ophezulu.
Nangona izongezo zidlala indima ebalulekileyo ekusebenzeni kweemveliso ze-aluminium alloy, abavelisi nabo kufuneka baphuhlise iinkqubo ezahlukeneyo ngokusekelwe kwiimpawu zezongezo ezahlukeneyo kunye namaqondo obushushu azo okusebenza. Umzekelo, i-chromium, i-manganese kunyeithusi kwi-aluminium alloy alloy zonke kufuneka zongezwe kuphela xa amaqondo obushushu azo okusebenza engaphezulu kwama-730°C, ngelixai-siliconkwayeisinyithikufuneka isetyenziswe kwindawo engama-740°C kunye nama-750°C ngokwahlukeneyo. Ukongeza, malunga nomthamo, i-zhelu ilawulwa ngokubanzi yile seti yeefomyula:
Ukusetyenziswa ngokuchanekileyo kwezongezo kuya kuqinisekisa umgangatho wokugqibela weemveliso ze-aluminium alloy.
Ukuqukumbela, izongezo ze-aluminium alloy zidlala indima ebalulekileyo ekuvelisweni kwee-alloys ezinobuhlobo nokusingqongileyo ezisebenza kakuhle. Ezi zongezo zinegalelo ekuzinzeni koshishino ngokugxila kwiinkqubo ezinobuhlobo nokusingqongileyo nezingangcolisiyo. Amandla azo okuphucula ulwakhiwo lweenkozo, ukwandisa umxholo wento kwi-alloy ye-aluminium kunye nokuphucula ukusebenza kwe-alloy kuzenza zibe yinto ebaluleke kakhulu kwiinkalo ezahlukeneyo. Njengoko imfuno yezinto ezinobuhlobo nokusingqongileyo nezisemgangathweni ophezulu iqhubeka ikhula, kuya kuba njalo nokubaluleka kwezongezo ze-aluminium alloy, ezivula indlela yekamva eliluhlaza nelisebenza ngakumbi.
