(1) Amandla kunye nokuqina kwe-polycrystals ye-magnesium ecocekileyo ayiphezulu.Ke ngoko, i-magnesium ecocekileyo ayinakusetyenziswa ngokuthe ngqo njengesixhobo solwakhiwo.I-magnesium ecocekileyo idla ngokusetyenziselwa ukulungisa i-magnesium alloys kunye nezinye i-alloys.
(2) I-Magnesium i-alloy yimathiriyeli yobunjineli eluhlaza kunye neyona nto iphuhliswayo kunye nokusetyenziswa okunamandla kwinkulungwane ye-21.
I-Magnesium inokwenza i-alloys nge-aluminium, ubhedu, i-zinc, i-zirconium, i-thorium kunye nezinye izinyithi.Xa kuthelekiswa ne-magnesium ecocekileyo, le alloy ineempawu ezingcono zomatshini kwaye yinto efanelekileyo yokwakha.Nangona i-alloys ye-magnesium ekhandiweyo ineempawu ezintle ezibanzi, i-magnesium yilatisi ene-hexagonal esondeleyo, enzima ukuyiqhuba ngeplastiki kwaye ineendleko eziphezulu zokulungisa.Ke ngoko, inani langoku le-alloys ye-magnesium esetyenzisiweyo lincinci kakhulu kunelo le-magnesium alloys.Kukho izinto ezininzi kwitheyibhile ye periodic enokuthi yenze i-alloys kunye ne-magnesium.I-Magnesium kunye nentsimbi, i-beryllium, i-potassium, i-sodium, njl. ayikwazi ukwenza i-alloys.Phakathi kwezinto ezisetyenziswayo zokuqinisa ingxubevange ye-magnesium, ngokwefuthe lezinto ezixubeneyo kwiipropathi zomatshini we-binary magnesium alloys, izinto ezixubileyo zinokwahlulwa zibe ziindidi ezintathu:
1. Izinto eziphucula amandla zezi: Al, Zn, Ag, Ce, Ga, Ni, Cu, Th.
2. Izinto eziphucula ukuqina zezi: Th, Ga, Zn, Ag, Ce, Ca, Al, Ni, Cu.
3. Izinto eziphucula ukuqina ngaphandle kotshintsho olukhulu kumandla: Cd, Ti, kunye noLi.
4. Izinto ezandisa kakhulu amandla kunye nokunciphisa ukuqina: Sn, Pd, Bi, Sb.
Impembelelo yezinto ezingcolileyo kwi-magnesium
A. Uninzi lwezinto ezingcolileyo eziqulethwe kwi-magnesium zineempembelelo ezimbi kwiipropati ze-mechanical of magnesium.
B. Xa i-MgO idlula i-0.1%, iimpawu zomatshini ze-magnesium ziya kuncitshiswa.
Xa umxholo we-C kunye no-Na udlula i-0.01% okanye umxholo we-K udlula i-0.03, amandla okuqina kunye nezinye iimpawu zomatshini we-magnesium nazo ziya kuncitshiswa kakhulu.
D. Kodwa xa zombini umxholo we-Na ufikelela kwi-0,07% kwaye umxholo we-K ufikelela kwi-0.01%, amandla e-magnesium awanciphi, kodwa kuphela iplastiki yayo.
Ukunganyangeki kwe-corrosion ye-high-purity magnesium alloy ilingana ne-aluminiyam
1. I-Matrix ye-Magnesium ye-alloy isondelene ne-hexagonal lattice, i-magnesium iyasebenza ngakumbi, kwaye ifilimu ye-oxide ikhululekile, ngoko ukuphosa kwayo, ukuguqulwa kweplastiki kunye nenkqubo yokuchasana ne-corrosion inzima kakhulu kune-aluminium alloy.
2. Ukuxhatshazwa kwe-corrosion ye-high-purity magnesium alloys ilingana okanye ingaphantsi kunaleyo ye-aluminium alloys.Ke ngoko, ukuveliswa kwemveliso ye-high-purity magnesium alloys yingxaki engxamisekileyo ekufuneka isonjululwe ekusetyenzisweni kobuninzi be-magnesium alloys.
