Aluminium Alloys: Izakhiwo kanye ngezinsimbi

Aluminium - edingeka kakhulu njengoba zensimbi ukwakhiwa, kanye neminye imikhakha yentuthuko izenzo zabantu. Nokho, njengoba injalo emsulwa isetshenziswa kakhulu kuyaqabukela. Inqubo esetshenziswa kakhulu njalo-aluminium.

Zonke Alloys zingahlukaniswa zibe ekubunjweni ngakwenza. Uhlobo lokuqala is oluqanjwe ukuncibilika Alloys for yokukhiqiza uhlobo lwesibili ingcindezi isicelo. Ekubunjweni aluminiyamu ngokuvamile uvezwa aluminium kwakwakhe ne-silicon. izinsimbi ezinjalo okuhlala, babe okusezingeni eliphezulu ukugqwala ukumelana, cut ezinhle. Kepha Alloys ekhandiwe, phakathi kwabo ezidumile kuyinto duralumin, lapho sakhiwo aluminium, magnesium nezethusi. Lokhu wire lensimbi ekhiqizwa, iphrofayli, ishidi, iteyipu. Inqubo ingxubevange kungenziwa eyethulwe nganoma iyiphi indlela.

Properties of aluminium Alloys zingahlukaniswa zibe ngokomzimba, mechanical futhi amakhemikhali. Ngokuphathelene Izakhiwo, le Alloys ngu kwabantu efanayo njengoba aluminium uqobo. Sinenkosi amandla okusezingeni eliphezulu, okuyinto ongancintisana titanium nensimbi. Kodwa lapha kufanele kuphawulwe ukuthi izinga lokushisa ukuncibilika ingxubevange lincane (kumayelana 200 degrees). Kuyaphawuleka ukuthi Alloys aluminium babe conductivity enhle ezishisayo, ngokuphawulekayo ukuqhuba kagesi ashiselwe kahle futhi livikela ukugqwala, nakuba aluminium okumsulwa, lezi izakhiwo siphakeme kakhulu kunalokhu.

Ngokuqondene izakhiwo mechanical, ziba ephakeme nge okwandisa degree of doping. Kwethulwa aluminiyamu ezisetshenziswa ukuze kwakhiwe izakhiwo yokulayisha ongaphakeme naphakathi. Kufanele kuqashelwe ukuthi izakhiwo Alloys basuke ikakhulu ishintshiwe emveni kokuba amalahle lokushisa ethile, ebheka futhi isebenzisa.

Njengoba ingxubevange ngaphambi kokusebenzisa isidingo ukucubungula, futhi ukuze kwenziwe imiklamo ethile alloying izakhi kufanele ashiselwe, kufanele sinake kakhulu iqiniso lokuthi le Welding aluminiyamu inezici ezithile. Inqubo has ezinye ubunzima:

- Alloys kanzima basuke eziphothene ngoba ifilimu oxide elivela phezu kwensimbi (ngokuvamile ingcolise omhlophe webhola, futhi lokhu kuphazamisa evamile alloying metal imiphetho);

- ifilimu oxide kanye ingxubevange uqobo babe ezahlukene ukuncibilika amaphuzu, umehluko kungaba eningi;

- kusukela ekubunjweni aluminium isandiso siphakeme ngokwanele, ngemva metal Welding kungaba zikhubazekile sina;

- Alloys abe inzuzo okusezingeni eliphezulu, ngakho imisinga Welding kungenzeka phezu kwensimbi.

Ukuze Welding Alloys ngokuyinhloko asetshenziswa carbon noma insimbi electrode. Le nqubo ibizwa olwenziwa nge zamanje njalo polarity okuphambene. Ngaphambi kokuqala umsebenzi ucezu umsebenzi baphathwe acetone noma benzine futhi ehlanzekile steel ibhulashi. Ukuze kangcono izinga Welding isidlulile, kubalulekile ukufudumeza izingxenye ashiselwe lokushisa predetermined (degrees 200). Ukuze uthole umphetho ezinhle ngemva Welding kufanele selehlile kancane.
