Indlela Yokuchonga Iintlobo Zesinyithi Nee-Alloys
Iintsimbi zizinto ezidlala indima ebalulekileyo kubomi bemihla ngemihla nakwimizi-mveliso. Zisetyenziswa kwiindlela ezahlukeneyo zokusebenza, ukusuka kwizakhiwo zokwakha kunye nokuveliswa kwezithuthi ukuya kwizinto ze-elektroniki. Nangona kunjalo, iintsimbi azisetyenziswa rhoqo kwimo yazo ecocekileyo. Endaweni yoko, zihlala zixutywa nezinye iintsimbi okanye izinto ezingezizo zesinyithi ukwenza ii-alloys ezineempawu eziphuculweyo. Ukuqinisekisa ukusetyenziswa ngokufanelekileyo nangokufanelekileyo, ukuchonga iintlobo zeentsimbi kunye nee-alloys zazo kubalulekile. Nantsi isikhokelo sokuchonga iintlobo ezahlukeneyo zeentsimbi kunye nee-alloys zazo.
1. Ukujonga Okubonakalayo
Ukujonga ngamehlo linyathelo lokuqala lokuchonga iintsimbi. Iimpawu zombala, ukukhazimla, kunye nokuma zinokubonelela ngezikhokelo zokuqala zohlobo lwentsimbi.
– Intsimbi nentsimbi: Inombala ongwevu okanye omnyama kwaye inzima. Intsimbi idla ngokuba nentsimbi ekhazimlayo ngenxa yomphezulu wayo ocwebezelayo.
– I-Aluminiyam: Isilivere ekhanyayo ngombala kwaye ilula xa ithelekiswa nezinye izinyithi.
– I-Copper: Inombala obomvu ohlukileyo kwaye ijika ibe luhlaza (patina) xa inyibilikisiwe.
– Ubhedu: Umxube wobhedu kunye netin, umbala omdaka ukuya kwigolide.
– Ibrass: Umxube wekopolo kunye ne-zinc, umbala otyheli ofana negolide.
– I-Nickel: Inombala omhlophe osiliva kwaye idla ngokukhazimla kakhulu.
– I-Titanium: Ingwevu yesilivere, ikhaphukhaphu, kodwa inamandla kakhulu.
2. Uvavanyo lweMagnetic
Ukusebenzisa imagnethi yindlela elula yokuchonga iintsimbi ze-ferromagnetic.

– IiMetals ezingezizo ezeFeromagnetic: I-aluminium, ubhedu, ubhedu, ubhedu, kunye netitanium azitsalwa ziimagnethi.
3. Uvavanyo loBulukhuni
Ukuqina kweentsimbi kunye nee-alloys kunokuvavanywa ngeendlela ezilula ezifana nokukrwela okanye ukusebenzisa isixhobo sokuvavanya ubunzima.
– Uvavanyo lokukrwela: Ukusebenzisa isixhobo esithile okanye esinye isinyithi ukukrwela umphezulu wesinyithi. Umzekelo, intsimbi yekhabhoni ilukhuni kune-aluminium.
– Uvavanyo loBulukhuni beRockwell okanye uBrinell: Ukusebenzisa isixhobo esikhethekileyo esibonelela ngexabiso lenani lobunzima ngokusekelwe kwi-inbonta eveliswa ngumthwalo othile.
4. Uvavanyo loxinano
Ukubala uxinano okanye uxinano lwesinyithi kunokunceda ekuchongeni kuba isinyithi ngasinye sinoxinano oluthile.
– Amanyathelo:
1. Linganisa isinyithi usebenzisa isikali esichanekileyo.
2. Linganisa umthamo wesinyithi ngokusifaka emanzini uze uqaphele utshintsho kumthamo wamanzi.
3. Bala uxinano usebenzisa le fomyula: Uxinano = Ubunzima / Umthamo.
Umzekelo woxinano:
– I-Aluminiyam: Malunga ne-2.7 g/cm³.
– Intsimbi/Intsimbi: Malunga ne-7.8 g/cm³.
– Ikhopha: Malunga ne-8.9 g/cm³.
– I-Titanium: Malunga ne-4.5 g/cm³.
5. I-Spectroscopy
I-Spectroscopy yindlela ephucukileyo esebenzisa ukukhanya ukuhlalutya ukwakheka kweekhemikhali zesinyithi.
– I-X-Ray Fluorescence (XRF): Isebenzisa ii-X-rays ukufumanisa izinto ezikhoyo kwisinyithi.
– I-Optical Emission Spectroscopy (OES): Ukusebenzisa ukukhanya okubonakalayo ukuhlalutya ukwakheka kweentsimbi kunye nee-alloys.
6. Uvavanyo lweeKhemikhali
Ukusetyenziswa kwee-reagents ezithile zeekhemikhali kunokubonelela ngeenkcukacha zokuba singubani isinyithi.
– Ukusabela kwi-Acids: Ezinye iimetali ezifana ne-aluminium kunye ne-iron zisabela ngokukhawuleza kwi-asidi, zivelisa igesi ye-hydrogen.
– Uvavanyo lombala wesisombululo: Umzekelo, ubhedu olukwisisombululo se-nitric acid luvelisa umbala oluhlaza okwesibhakabhaka oqaqambileyo.
7. Uhlalutyo lweMicrological
Ukujonga isakhiwo se-microscope nge-metallurgical microscope kunokubonelela ngolwazi oluneenkcukacha malunga nesigaba kunye nesakhiwo sesinyithi okanye i-alloy.
– Ukuqwalaselwa kwemida yeenkozo: Ukuma kunye nobukhulu beenkozo zekristale kwisinyithi kunokubonelela ngezikhokelo malunga nohlobo kunye nenkqubo yokwenziwa kwesinyithi okanye i-alloy.
