Ngaphambi kokuba siqonde indlela yokuchonga nokukhetha izinto zeCuNi44, kufuneka siqonde ukuba yintoni i-copper-nickel 44 (CuNi44). I-Copper-nickel 44 (CuNi44) yi-alloy ye-copper-nickel. Njengoko igama layo lisitsho, i-copper yenye yezona zinto ziphambili ze-alloy. I-Nickel ikwayenye yezona zinto ziphambili, enomxholo we-43.0% - 45.0%. Ukongezwa kwe-nickel kunokuphucula amandla, ukumelana nokugqwala, ukumelana kunye neempawu ze-thermoelectric ze-alloy. Ukongeza, ibandakanya kodwa ayikhawulelwanga kwi-0.5% - 2.0% ye-manganese. Ubukho be-manganese bunceda ukuphucula ukumelana nokugqwala, ukuzinza kobushushu kunye namandla e-alloy, kodwa i-manganese egqithisileyo inokubangela ubuqhophololo.
I-Copper-nickel 44 inomlinganiselo ophantsi wokumelana nobushushu, kwaye ukumelana kwayo kuzinzile xa ubushushu butshintsha, nto leyo eyenza ukuba ibe luncedo kwiindawo apho kufuneka uzinzo lokumelana. Xa iphantsi koxinzelelo kunye nokuguquguquka, isizathu sokuba i-copper-nickel 44 ikwazi ukugcina ukusebenza okuzinzileyo kukuba umlinganiselo wayo wokuziva uxinezelekile awutshintshi kangako ngexesha loxinzelelo lweplastiki kwaye i-mechanical hysteresis incinci. Ukongeza, i-CuNi44 inamandla amakhulu okushisa umbane kwi-copper, inamandla amahle okuwelda, kwaye ilungele ukucutshungulwa kunye nokuqhagamshelwa.
Ngenxa yeempawu zayo ezilungileyo zombane nezoomatshini, iCuNi44 idla ngokusetyenziselwa ukuvelisa izinto ezahlukeneyo ze-elektroniki ezifana nee-resistor, ii-potentiometers, ii-thermocouples, njl.njl., umzekelo, njengecandelo eliphambili kwizixhobo zombane ezichanekileyo. Kwicandelo lemizi-mveliso, ingasetyenziselwa ukuvelisa iibhokisi zokumelana nemizi-mveliso ezinomthwalo omninzi, ii-rheostats kunye nezinye izixhobo. Ngenxa yokumelana kwayo nokugqwala okuhle, ikwafanelekile nakwiindawo ezineemfuno eziphezulu zokuxhathisa ukugqwala ezifana noomatshini beekhemikhali kunye nezinto zenqanawa.
Xa sithenga iimveliso, sizibona njani izinto zeCuNi44? Nazi iindlela ezintathu zokuchonga onokuzisebenzisa.
Okokuqala, eyona ndlela ilula kukusebenzisa izixhobo zobungcali zohlalutyo lweekhemikhali.Ezifana nee-spectrometer, njl.njl., ukuvavanya ukwakheka kwezinto. Qinisekisa ukuba umxholo wobhedu usele, umxholo we-nickel yi-43.0% - 45.0%, umxholo wesinyithi yi-≤0.5%, umxholo we-manganese yi-0.5% - 2.0%, kwaye ezinye izinto zingaphakathi koluhlu oluchaziweyo. Xa abathengi bethu bethenga iimveliso ze-tankii, singabanika isatifikethi somgangatho okanye ingxelo yovavanyo lwezinto.
Okwesibini, chonga kwaye uhlole iimpawu zembonakalo yemveliso.Izinto zeCuNi44 zihlala zibonisa ukukhazimla kwesinyithi, kwaye umbala unokuba phakathi kobhedu kunye ne-nickel. Jonga ukuba umphezulu wezinto uthambile, awunaziphene zibonakalayo, i-oxidation okanye umhlwa.
Indlela yokugqibela kukuvavanya iimpawu zomzimba zemveliso - ukulinganisa uxinano kunye nobunzima bezinto.I-CuNi44inoluhlu oluthile loxinano, olunokuvavanywa zizixhobo zokulinganisa uxinano zobungcali kwaye luthelekiswe nexabiso eliqhelekileyo. Ingalinganiswa nangomvavanyi wobunzima ukuqonda ukuba ubunzima bayo buyahambelana noluhlu lobunzima oluqhelekileyo lwe-copper-nickel 44.
Imakethi inkulu kangaka, ungakhetha njani umthengisi ohlangabezana neemfuno zethu zokuthenga?
Ngexesha lophando, abathengi kufuneka bacacise iimfuno zokusetyenziswa.Umzekelo: misela indlela ethile yokusebenzisa izinto. Ukuba zisetyenziselwa ukwenziwa kwezinto ze-elektroniki, iimpawu zazo zombane, ezifana nomlinganiselo wobushushu ophantsi kunye nokusebenza kakuhle kwe-welding, kufuneka ziqwalaselwe; ukuba zisetyenziselwa oomatshini beekhemikhali okanye izinto zenqanawa, ukumelana kwazo nokugqwala kubaluleke ngakumbi. Xa zidityaniswe nokusetyenziswa kwesiphelo, ubushushu, uxinzelelo, ukugqwala kunye nezinye izinto ezikwindawo yokusetyenziswa ziyathathelwa ingqalelo ukuqinisekisa ukuba i-CuNi44 esiyithengayo inokusebenza ngokuqhelekileyo phantsi kwezi meko.
Ngaphezu koko, ngexesha lophando, ungavavanya umthengisi ngokujonga isatifikethi sokufaneleka komthengisi, uvavanyo lwabathengi, udumo lweshishini, njl. Ungamcela ngokuthe ngqo umthengisi ukuba anike isiqinisekiso somgangatho wezinto kunye neengxelo zovavanyo ukuqinisekisa ukuba umgangatho wezinto uthembekile.
Ukongeza kwezi ngongoma zimbini zingentla, ulawulo lweendleko nalo lubalulekile.Kufuneka sithelekise amaxabiso ababoneleli abahlukeneyo. Kakade ke, asinakusebenzisa ixabiso kuphela njengeyona ndlela yokukhetha. Kubalulekile ngokulinganayo ukuqwalasela izinto ezifana nomgangatho wezinto, ukusebenza kunye nenkonzo yasemva kokuthengisa. Ubomi benkonzo yezinto ezisetyenzisiweyo bunxulumene ngokuthe ngqo neendleko zokugcinwa kwazo. Izinto ezisemgangathweni ophezulu zeCuNi44 zinokuba neendleko zokuqala eziphezulu, kodwa zinokonga iindleko zokugcinwa kunye nokutshintshwa kwazo xa zisetyenziswa ixesha elide.
Okokugqibela, kufanelekile ukukhankanya ukuba ngaphambi kokuba uthenge iimveliso ngomlinganiselo omkhulu, ungacela umthengisi ukuba akunike iisampulu zokuvavanya. Vavanya ukuba ukusebenza kwezinto ezisetyenzisiweyo kuyahlangabezana neemfuno, ezinje ngeempawu zombane, ukumelana nokugqwala, iimpawu zoomatshini, njl. Ngokusekelwe kwiziphumo zovavanyo, misela ukuba ukhetha nai-copper-nickel 44izinto zomthengisi.
