Iimpawu zeZinc Alloys

Iimpawu eziphambili:

Uxinano oluphezulu.

Iimpawu ezilungileyo zokuphosa; ziyakwazi ukuvelisa iindawo ezintsonkothileyo nezinodonga oluncinci kunye neendawo ezigudileyo.

Ifanelekile kunyango lomphezulu: ukufakelwa nge-electroplating, ukugquma ngomgubo, kunye nokupeyinta.

Ayitsali intsimbi ngexesha lokunyibilika nokugaywa ngedayi, ayibolisi idayisi, kwaye ayinamatheli kwisikhunta.

Iipropati ezibalaseleyo zoomatshini kunye nokumelana nokuguguleka kubushushu begumbi.

Iqondo lokunyibilika eliphantsi (385°C), okwenza kube lula ukunyibilika.

Amanqaku Okufanele Uwaqaphele Ngexesha Lokusetyenziswa:

Ukumelana nokugqwala okubi

Xa izinto ezingcolisayo ezifana ne-lead, i-cadmium, kunye ne-tin zidlula imida eqhelekileyo kwi-alloy composition, ibangela ukuba i-casting iguge kwaye iguge, ibonakale njengokwanda komthamo kunye nokwehla okukhulu kweempawu zoomatshini—ingakumbi i-plasticity—kwaye inokukhokelela ekuqhekekeni ngokuhamba kwexesha. I-lead, i-tin, kunye ne-cadmium zinyibilika kancinci kakhulu kwi-zinc alloys kwaye ngoko ke zigxile kwimida yeenkozo, zisebenza njenge-cathodes, ngelixa isisombululo esiqinileyo esityebileyo kwi-aluminium sisebenza njenge-anode. Xa kukho umphunga wamanzi (i-electrolyte), oku kukhuthaza ukubola kwe-electrochemical intergranular. Iinxalenye ezifakwe kwi-die-cast ziyaguga ngenxa yokubola kwe-intergranular.

Iziphumo zokwaluphala

Ulwakhiwo oluncinci lwee-alloys ze-zinc luquka ikakhulu izisombululo eziqinileyo ezicebileyo ze-zinc eziqulethe i-Al kunye ne-Cu, kunye nezisombululo eziqinileyo ezicebileyo ze-Al eziqulethe i-Zn. Ukunyibilika kwazo kuncipha njengoko ubushushu buhla. Nangona kunjalo, ngenxa yesantya sokuqina esikhawulezayo kakhulu seendawo ezidityanisiweyo, ukunyibilika kwezi zisombululo ziqinileyo kugcwala kakhulu xa inxalenye ifikelela kubushushu begumbi. Emva kwexesha elithile, olu xinzelelo luyaphela kancinci kancinci, nto leyo ebangela utshintsho oluncinci kwimo kunye nobukhulu be-casting.

Imida yoBushushu

Ii-die-castings ze-zinc alloy akufuneki zisetyenziswe kwiindawo zokusebenza ezinobushushu obuphezulu okanye obuphantsi (ngaphantsi kwe-0°C). Ii-zinc alloys zibonisa iimpawu ezilungileyo zoomatshini kubushushu begumbi. Nangona kunjalo, amandla okuxinana ayancipha kakhulu kubushushu obuphezulu, kwaye amandla okuchaphazeleka ayancipha kakhulu kubushushu obuphantsi.

Iintlobo zeZinc Alloys

Uhlobo lwe-alloy	Iimpawu kunye nezicelo
I-Zamak 3	Ukutyibilika kakuhle kunye neempawu zoomatshini. Isetyenziselwa ukuthunga izinto ezifuna amandla aphantsi oomatshini, njengeethoyi, izixhobo zokukhanyisa, izinto zokuhombisa, kunye nezinye izinto zombane.
I-Zamak 5	Ukutyibilika kakuhle kunye neempawu ezibalaseleyo zoomatshini. Isetyenziselwa ukwenziwa kwezinto ezifunekayo ukuze zibe namandla aphakathi oomatshini, njengeenxalenye zemoto, iinxalenye ze-electromechanical, iinxalenye zoomatshini, kunye neenxalenye zombane.
I-Zamak 2	Isetyenziselwa iindawo zoomatshini ezineemfuno ezikhethekileyo zokusebenza koomatshini, iimfuno zobulukhuni obuphezulu, kunye neemfuno zokuchaneka ngokubanzi.
I-ZA8	Ukutyibilika okuhle kunye nokuzinza okulinganayo, kodwa ukutyibilika okubi. Isetyenziselwa ukwenza izinto zokusebenza ezincinci ezinobukhulu obuphezulu kunye neemfuno zombane, ezifana nezixhobo zombane.
I-Superloy	Ukutyibilika okufanelekileyo, okusetyenziselwa ukwenza izinto zokusebenza ezidityanisiweyo, ezinkulu, ezichanekileyo nezintsonkothileyo, ezifana nezixhobo zombane kunye neendawo zazo ezivalekileyo.

Ii-alloy ze-zinc ezahlukeneyo zineempawu ezahlukeneyo zomzimba nezoomatshini, nto leyo enika ukuguquguquka kuyilo lweendawo ezidityanisiweyo.

Ukukhethwa kwee-Zinc Alloys

Ukukhethwa kwe-zinc alloy kuxhomekeke kakhulu kwizinto ezintathu:

Indlela ekucetywayo ukusetyenziswa ngayo inxalenye ediyelwe kunye neenkcukacha zokusebenza ezifunekayo.

(1) Iipropati zoomatshini

Amandla okutsalwa, okukuko ukumelana okuphezulu kwezinto ngaphambi kokuba zaphuke; ubude, obulinganisa ibhalansi phakathi kokuqhekeka kunye nokuguguleka; kunye nobunzima, obukuko ukumelana komphezulu wezinto kwi-deformation yeplastiki ebangelwa kukuxinana okanye ukungqubana okuvela kwinto eqinileyo.

(2) Iimeko zeNdawo yokuSebenza

Ubushushu bokusebenza, ukufuma, imidiya edibana nayo into yokusebenza, kunye neemfuno zokungabi namoya.

(3) Iimfuneko zokuchaneka

Ukuchaneka okunokufikelelwa kunye nokuzinza okulinganayo.

Ukuqhubekeka kakuhle

(1) Inkqubo yokuphosa
