Uhlalutyo oluneenkcukacha loMahluko

1. Ukubunjwa kwemichiza kunye nokusebenza okungundoqo

Umahluko ongundoqo ulele kumlinganiselo we-nickel-chromium: i-Nicr7030 iqulethe i-30% yechromium (engaphezulu kune-Nicr8020's 20%), eyenza i-ductility yayo kunye ne-weldability. Ngobude bekhefu le-≥25%, i-Nicr7030 inokutsalwa kwiintambo ezicolekileyo kakhulu (ukuhla ukuya kwi-0.01mm) okanye zigotywe zibe ziimo ezintsonkothileyo, ziyenze ilungele iimveliso ezifuna ukucutshungulwa ngokuchanekileyo (umzekelo, iingcingo zokufudumeza izitulo zemoto, i-miniaturized electronic sensors).

Ngokwahlukileyo, umxholo we-nickel ophezulu we-Nicr8020 (i-80%) uphucula ukuzinza kwayo okuphezulu kobushushu, ukuvumela ukuba isebenze ngokuqhubekayo kwi-1300 ° C-50 ° C ngaphezu kwe-Nicr7030. Nangona kunjalo, oku kuza kwiindleko zokunciphisa i-ductility (kuphela ≥15%), okwenza kube ngaphantsi kokufaneleka ukugoba okanye ukwenza iinkqubo. Ezinye iimodeli ezifana ne-Nicr6040 zinomxholo ophantsi we-nickel, obangela ukuxhathisa okuphantsi kunye nokumelana nobushushu, ukunciphisa ukusetyenziswa kwazo kwiimeko eziphantsi kwemfuno.

2. Ukuxhathisa kunye nokuSebenza kwaMandla

Ukuchasana kuchaphazela ngokuthe ngqo ukusebenza kakuhle kokufudumeza kunye noyilo lwamacandelo. I-Nicr8020 inoxhathiso oluphezulu (1.40 Ω·mm²/m), oku kuthetha ukuba ivelisa ubushushu obungaphezulu ngobude beyunithi nganye phantsi komsinga ofanayo, iyenza ilungele izinto zokufudumeza zamandla aphezulu (umzekelo, iifurnasi zobushushu obuphezulu).

I-Nicr7030's imodareyitha ukumelana (1.18 Ω·mm²/m) ibetha ibhalansi phakathi kokuveliswa kobushushu kunye nokusetyenziswa kwamandla. Kwiinkqubo ezininzi zemizi-mveliso kunye nabathengi (umzekelo, ii-oveni, iipadi zokufudumeza), ibonelela ngamandla awoneleyo okufudumeza ngelixa inciphisa inkcitho yamandla. Ukongezelela, ukunyamezela kwayo okuzinzile (± 0.5% ukunyamezela) kuqinisekisa ukusebenza okuhambelanayo ngokusetyenziswa kwexesha elide, ukuphepha ukuguquka kweqondo lokushisa.

3. Ukumelana ne-Oxidation kunye noBomi beNkonzo

Zombini i-Nicr7030 kunye ne-Nicr8020 zenza iifilimu ezikhuselayo ze-Cr₂O₃ kumaqondo obushushu aphezulu, kodwa umxholo wechromium weNicr7030 udala ifilimu exineneyo, eyomelele ngakumbi. Oku kuyenza ixhathise "i-green rot" (i-intergranular oxidation) kwindawo efumileyo okanye yokunciphisa umoya, ukwandisa ubomi bayo benkonzo ukuya kwiiyure ezingama-8000+ (i-20% ubude kune-Nicr8020 kwiindawo ezinzima).

I-Nicr6040, enomxholo ophantsi we-chromium, inefilimu ye-oxide engazinzanga ekulungele ukuxobulwa kumaqondo okushisa angaphezu kwe-1000 ° C, ekhokelela kubomi obufutshane benkonzo kunye nokunyuka kweendleko zokugcina.

4. Iindleko kunye nokuziqhelanisa nesicelo

I-Nicr7030 inikezela ngeendleko eziphezulu kakhulu: umxholo wayo ophantsi we-nickel (xa kuthelekiswa ne-Nicr8020) unciphisa iindleko ze-raw material nge-15-20%, ngelixa ukusebenza kwayo okuguquguqukayo kugubungela i-80% yeemeko zesicelo se-nichrome wire. Lolona khetho lukhethwayo kwiimveliso eziveliswe ngobuninzi ezifana nezixhobo zasekhaya kunye neenkqubo zokufudumeza iimoto, apho ukulungelelanisa ukusebenza kunye neendleko kubaluleke kakhulu.

Umxholo we-nickel ophezulu we-nickel we-Nicr8020 wonyusa iindleko zawo, okwenza kube yimfuneko kuphela kwizicelo ezikhethekileyo zobushushu obuphezulu (umzekelo, uvavanyo lwecandelo le-aerospace). Ezinye iimodeli ezine-nickel ephantsi njenge-Nicr6040 zinexabiso eliphantsi kodwa zisilela ukusebenza ukuhlangabezana neemfuno zemizi-mveliso okanye ezichanekileyo zombane.

Isikhokelo soKhetho
