Imbali kunye nezicelo ze-Monel Alloys

I-Monel yayiyi-Forerunner yeNsimbi Engenasici

I- alloys i- Monel® i- nickel -based alloys equle phakathi kwe-29 ne-33 yeepesenti zobhedu . Ekuqaleni wadalwa ngu-metallurgist uRobert Crooks uStanley kwaye unelungelo lobunikazi ngo-1905 yi-International Nickel Inkampani. Isitya sanikwa igama elithi Monel ngokuhlonipha umlawuli we-International Nickel. Akumangalisi ukuba uStanley waba nguMlawuli we-International Nickel.

Ngomnyaka we-1908, i-Monel yayisetyenziswe njengento yokuphahla kwi-Pennsylvania Station eNew York.

Ngexesha lama-1920 nangemva kamva, i-Monel yayisetyenziselwa ukuhlaziywa, ukucwina, izixhobo zombane kunye nophahla olukhanyayo. Ngoxa i-Monel yayiphakathi kweentsimbi ezithandwa kakhulu kwiimarike nge-1940, ngokukodwa kwakugqitywa ngamashishini angenasininzi angenasiphelo ukusuka kuma-1950 ukuya phambili.

Iintlobo zeMonel

Kukho iintlobo ezintandathu zeMonel. Zonke ziqulethe ipesenti enkulu ye-nickel (ukuya kuma-67%), ngelixa insimbi, i-manganese, i-carbon, kunye / okanye i-silicon. Izongezo ezincinci ze- aluminium kunye ne- titanium , eyenza i-al-alloy-alloy, ukunyusa amandla, ngokukodwa kumaqondo aphezulu aphezulu, okwenza kube luncedo kwizicelo ze-aerospace.

Ukusetyenziswa kweMonel

I-alloys yaseMonel® idlalwa rhoqo kwizinto zokuvelisa iikhemikhali ngenxa yokumelana nokuqineka kwamachiza.

Ziye zisetyenziswe kwimboni ye-aerospace. Imveliso ekwakhiwe kunye ne-Monel (ingakumbi ngaphambi kokufika kwentsimbi engenantshintshi) ibandakanya ukutshintshisa ukushisa, ukuvelisa izixhobo zomshishini, izixhobo zomoya, iindlela zokupakisha, iiferethi zamanzi kunye namanzi, iitshini zekhishi kunye nokuphahla.

Iinkonzo kunye neNgqungquthela yaseMonel

Iinkonzo:

I-alloys yaseMonel® inomsebenzi omkhulu wokunikela.

Ngaphambi kwee-1950, babeye "ukuya" kukhetho kwiimveliso ezininzi ezibalulekileyo. Kwakhona kungadibaniswa ngokulula, kugqityiwe kwaye kukhange. Oku kungenxa yalo:

• ukuxhatshazwa kwe- acrotic resistance to acids kunye ne-alkalis
• amandla aphezulu
• ulungelelwano oluhle (olulula ukuma kunye nefomu)
• ukuchasa kwi-alkalis
• indleko ephantsi
• Ukufumaneka kwiifom ezahlukeneyo kubandakanya amashishini ashushu kunye nebandayo, iiplates, iintonga, imivalo kunye neethubhu
• ubukeka obukhangayo kunye nokugqiba, kubandakanywa ne-patina ebomvu efana nobhedu

Umgcini:

Ngoxa i-Monel ineenzuzo ezininzi, lide livela kwisinyithi esipheleleyo. Ukuchithwa kwezi ntlanzi zihluphekile ngenxa yokuthambekela kwabo ngokukhawuleza ukusebenza-nzima. Yintoni egqithisile:

• Nangona i-surface discoloration kwi-patina inokuba yinto ekhangayo kwezinye iimeko, ingabangela iingxaki kwabanye.
• Ngelixa lixhathisa ukubola, liyakwazi ukugqithiswa xa lucaciswa ngamanzi atyuwa.
• Ngelixa iimeko ezixhatshazelisayo phantsi kweemeko ezininzi, iyakrhoxiswa xa ibonakala kwizinto ezithile. Ngokomzekelo, i-nitric oxide, i-nitrous acid, i-sulfur dioxide, kunye ne-hypochlorite zizinto zonke ezinokubhubhisa i-Monel.
• Ukuba khona kweMonel kunokukhokelela ekugqibeleni kwe-galvanic. Ngamanye amagama, ukuba i-aluminium, i-zinc, okanye isinyithi isetyenziswe njenge-fasteners ye-Monel kwaye yachaphazeleka kwiimeko ezithile, i-metal fasteners iya kuphazamiseka ngokukhawuleza.
