Monel 400 ndi Monel 405 ndi ma alloy awiri ofanana kwambiri a nickel-copper omwe ali ndi mphamvu zofanana zopewera dzimbiri. Komabe, palinso kusiyana pakati pawo:
1. Kapangidwe kake:
Monel 400 imapangidwa ndi pafupifupi 67% nickel ndi 30% mkuwa, ndipo ili ndi zinthu zina zochepa monga chitsulo, manganese ndi silicon. Kumbali ina, Monel 405 ili ndi kapangidwe kosintha pang'ono ndi kuwonjezera pang'ono (0.5-1.5%) ya aluminiyamu. Kuwonjezera kumeneku kumathandiza kukonza mawonekedwe a makina a alloy ndikuwonjezera mphamvu zake. , ndi zina zotero.
2. Mphamvu ndi kuuma:
Chifukwa cha kuwonjezera aluminiyamu, Monel 405 imakhala ndi mphamvu komanso kuuma kwambiri kuposa Monel 400. Izi zimapangitsa Monel 405 kukhala yoyenera kwambiri pakugwiritsa ntchito komwe kumafuna mphamvu komanso kuuma kwakukulu.
3. Kutha kupotoza:
Poyerekeza ndi Monel 400, Monel 405 ikuwonetsa kusinthasintha kwa kulumikiza. Kuwonjezera aluminiyamu kumathandiza kuchepetsa kupangika kwa ma carbide pakati pa granular panthawi yolumikiza, kumawonjezera kusinthasintha kwa alloy, komanso kuchepetsa chiopsezo cha ming'alu ya kulumikiza.
4. Kugwiritsa ntchito:
Chifukwa cha kukana dzimbiri bwino, makamaka m'madzi a m'nyanja, Monel 400 imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikizapo za m'madzi, kukonza mankhwala, mafuta ndi gasi. Monel 405 imapereka mphamvu yowonjezera komanso kuthekera kowongoleredwa ndipo imagwiritsidwa ntchito kwambiri pazinthu monga ma pump shafts, zomangira ndi zida za valve.
5. Perekani munthu wapadera:
Kukhala ndi udindo pakukonzekera ndi kugwirizanitsa ntchito yophunzitsa motokuonetsetsa kuti ntchito yobowola ikuyenda bwino.
Ponseponse, ngakhale kuti Monel 400 ndi Monel 405 zonse zili ndi mphamvu yolimbana ndi dzimbiri, Monel 405 imapereka mphamvu yowonjezera komanso kuthekera kowongoleredwa poyerekeza ndi Monel 400, zomwe zimapangitsa kuti ikhale chisankho chabwino kwambiri pa ntchito zina.
