Kanal AF Alloty 837 Phissistohm alchrome y fecray alloy

I-Kanthal af yi-ferricuric i-iron-chromium-alloum alloy (i-fecral alloy) yokusetyenziswa kumaqondo obushushu ukuya kuthi ga kwi-1300 ° C (2370 ° F). I-alloy ibonakaliswa ngokuchasene ne-oxidation egqwesileyo kunye nokuzinza okuhle kakhulu okubangelwa bubomi obude.

I-Kan-thal af isetyenziswa rhoqo kwizinto zokufudumeza zombane nezixhobo zemizi-mveliso nakwizixhobo zasekhaya.

Umzekelo wemizi-mveliso yesixhobo ivulekile i-SICA ye-TARTS, kwi-meander yezinto ezinamafutha ezi-faramic kwi-firding ye-faramic ye-faramic ye-faramic, kwi-COIR YOKUZIPHATHA NGOKUGQIBELA Ii-radiator, izitshisi zokuhambisa i-porcupine zemipu yomoya eshushu, iiradiators, ezomisi.

I-Afting kwisifundo esikhoyo, indlela yokulinganisa ye-fecral alloy (kanal af) ngexesha lokungena kwi-nitrogen igesi (4.6) nge-900 ° C kwaye i-1200 ° C ichaziwe. Iimvavanyo ze-isothermal kunye ne-thermo-cyclic kunye namaxesha apheleleyo evele, amazinga okufudumeza, kunye namaqondo obushushu athululwayo eyenziwa. Uvavanyo lwe-oxidation emoyeni kunye ne-nitrogen igesi yenziwa ngohlalutyo lwe-thermogramelimpric. ULWAZI LWE-MARICS luphawuleka ngokuskena i-scan skutron microscopy (i-sem -dx), i-augter ye-Augn Spectroscopy (AES), kunye ne-Ion yeBib-EDX). Iziphumo zibonisa ukuba ukuqhubela phambili kwe-corrosion yenzeka ngokusekwa imimandla ye-subrication yasekhaya, equlwe amasuntswana e-ALN, enciphisa umsebenzi wealuminium kwaye ibangela ukutshisa kunye nokutshiza. Ukukhula kwe-al-nitrive kunye nokukhula kwe-al-oxide i-al-oxide kuxhomekeke kubushushu obushushu kunye nokufudumeza. Kwafunyaniswa ukuba i-ndridation ye-fecral yinkqubo yokuqhushumba kunokuba yi-oxidotion ngexesha lokungena kwi-nitrogen igesi kunye nonyango oluphambili lwe-ALTY.

Intshayelelo ye-Fecrolic-I-Alloys esekwe (Kanal AF ®) eyaziwa ngokuba yixhasi eliphezulu le-oxidation kwiqondo lobushushu eliphakamileyo. Le ndlu ibalaseleyo ihambelana nokusekwa kwe-Aloumina ye-Alumina yoLungiso kumphezulu, okhusela umxholo nxamnye ne-oxidation enye [1]. Ngaphandle kweepropathi zokuchasana nokuxhaphaza ubuqhetseba, ubomi bezinto ezenziwe ukusuka kwi-Fecroys - izabelo ezisekwe kwi-fecrals zinokulinganiselwa ukuba iindawo zihlala zivezwa ngebhayisekile ye-thermal kumaqondo obushushu aphezulu [2]. Esona sizathu soku kukuba isikali senze into, ialuminiyam, ityiwa kwi-Aloty Matrix kwindawo yokufumana i-subso-yothuko kunye nokutshintsha kwe-Aloumina. Ukuba umxholo we-aluminium oshiyekileyo uyancipha phantsi koxinzelelo oluphambili, i-Alloty ayinakuguqula isikali sokukhusela, esikhokelela kwi-oxiday ye-Iron esekwe kwi-Iron kunye ne-chromium esekwe kwi-3,4]. Kuxhomekeka kwimozulu ejikelezileyo kunye nokungafikeleli kwee-oxides ezingaphezulu kwe-Ox kunokuqhubela phambili ukuqhuba i-oxidation ye-oxidation ephezulu okanye i-ndridation kunye nokwenziwa kwezigaba ezingafunekiyo kwingingqi ye-5]. I-HAN kunye nabaselula bayibonisa loo nto kwi-Aluminiing Hung I-Al Alloys, indlela enobunzima ye-oxidation ye-oxidation ikhula [i-witsing ye-oxting ehambelana ne-Altrays enama-4] e-4]. Izikali ze-chromium ze-oxide ziyaziwa ukuba yi-nitrogen efihlakeleyo, kunye ne-CR2 N ingaba ngumaleko ongaphantsi okanye njengongaphantsi [8,9]. Esi siphumo sinokulindeleka ukuba sibe nzima ngakumbi phantsi kweemeko zeqhwa ngebhayisikile ezikhokelela ekuchitheni izithuba ze-oxide kwaye kuncitshiswe ukusebenza kwayo njengomqobo kwi-nitrogen [6]. Ukuziphatha kolonwabo kulawulwa lukhuphiswano phakathi kwe-oxidition, olukhokelela kwi-Itrogen ye-Aln i-Aln iSigaba se-ALN xa ithelekiswa ne-Alloy Matrix [9]. Xa ityhila i-fecrals kwiqondo lobushushu eliphezulu kwi-oxygen okanye ezinye ii-oxygen ezifana ne-H2O okanye i-Aluminie COUSTER kwi-OXYGENT okanye i-ALUMINE kwiqondo lokuphakamisa kunye nokubonelela ngokungenayo kwi-Altrad Matrix. Kodwa, ukuba ityhilwe kwimozulu yonciphiso (i-H2 + i-H2), kunye nokukhusela i-Alweumina ye-Alweuminay, i-Oxiday ye-Oxibey yeNdawo eNgeyo kwi-Matrix ye-Nitrogen kwi-Ferrix kunye nokuqulunqwa kwesigaba se-ALN [9]. Ukukhusela (4.6) I-Nitrogen Bommord ihlala isetyenziswa rhoqo kwisicelo semveliso ye-Fecral Alloys. Umzekelo, ukuxhathisa izitshisi ezikwimililo yonyango lobushushu kunye nemozulu ye-nitrogen ekhuselayo ngumzekelo wokusetyenziswa kwe-fecral we-Ferals kwindawo enjalo. Ababhali banika ingxelo yokuba inqanaba le-oxidation le-Ficrey Alloys licotha kakhulu xa ihlanjululwa kwimozulu yeoksijini ye-Oxhlagegen. Injongo yesifundo yayikukufumanisa ukuba ingaba i-Aneald (99.996) i-Nitrogen (4.6) igesi (i-Messer ® ichaphazela kangakanani i-ferrosion ye-Alloray (i-ANSERE), yahluka kakhulu (kunye nenqanaba lokufudumeza), kunye nenqanaba lokufudumeza.
