Alloy-orisun nickel Waye pẹlu Passivation
Wọpọ Orisi ti Nickel Alloys
Nickel yoo ni irọrun alloy pẹlu ọpọlọpọ awọn irin bii Ejò, chromium, irin, ati molybdenum.Afikun ti nickel si awọn irin miiran ṣe iyipada awọn ohun-ini ti alloy Abajade ati pe o le ṣee lo lati ṣe agbejade awọn abuda ti o fẹ gẹgẹbi imudara ipata tabi resistance ifoyina, iṣẹ ṣiṣe iwọn otutu ti o pọ si, tabi awọn iyeida kekere ti imugboroosi gbona, fun apẹẹrẹ.
Awọn apakan ti o wa ni isalẹ ṣafihan alaye nipa ọkọọkan awọn iru awọn ohun elo nickel wọnyi.
Nickel-Irin Alloys
Nickel-iron alloys ṣiṣẹ ni awọn ohun elo nibiti ohun-ini ti o fẹ jẹ iwọn kekere ti imugboroosi gbona.Invar 36®, ti o tun ta pẹlu awọn orukọ iṣowo ti Nilo 6® tabi Pernifer 6®, ṣe afihan olùsọdipúpọ ti imugboroja igbona ti o jẹ iwọn 1/10 ti erogba, irin.Iwọn giga giga ti iduroṣinṣin onisẹpo n ṣe awọn alloys nickel-iron wulo ninu awọn ohun elo bii ohun elo wiwọn deede tabi awọn ọpa igbona.Awọn ohun elo nickel-iron miiran pẹlu awọn ifọkansi ti nickel paapaa ni a lo ninu awọn ohun elo nibiti awọn ohun-ini oofa rirọ ṣe pataki, gẹgẹbi awọn oluyipada, inductor, tabi awọn ẹrọ ibi ipamọ iranti.
Nickel-Ejò Alloys
Awọn alloys nickel-copper jẹ sooro pupọ si ipata nipasẹ omi iyọ tabi omi okun ati nitorinaa wa ohun elo ninu awọn ohun elo omi.Gẹgẹbi apẹẹrẹ, Monel 400®, ti o tun ta labẹ awọn orukọ iṣowo nickelvac® 400 tabi Nicorros® 400, le wa ohun elo ni awọn ọna fifin omi, awọn ọpa fifa, ati awọn falifu omi okun.Yi alloy bi ifọkansi ti o kere ju ti 63% nickel ati 28-34% Ejò.
Nickel-Molybdenum Alloys
Nickel-molybdenum alloys nfunni ni resistance kemikali giga si awọn acids ti o lagbara ati awọn idinku miiran bii hydrochloric acid, hydrogen chloride, sulfuric acid, ati phosphoric acid.Atike kemikali fun alloy ti iru yii, gẹgẹbi Alloy B-2®, ni ifọkansi ti molybdenum ti 29-30% ati ifọkansi nickel ti laarin 66-74%.Awọn ohun elo pẹlu awọn ifasoke ati awọn falifu, gaskets, awọn ohun elo titẹ, awọn paarọ ooru, ati awọn ọja fifin.
Nickel-Chromium Alloys
Awọn alloys nickel-chromium ni o ni idiyele fun resistance ipata giga wọn, agbara iwọn otutu giga, ati resistance itanna giga.Fun apẹẹrẹ, alloy NiCr 70/30, ti o tun jẹ apẹrẹ bi Ni70Cr30, Nikrothal 70, Resistohm 70, ati X30H70 ni aaye yo ti 1380oC ati resistivity itanna ti 1.18 μΩ-m.Awọn eroja gbigbona gẹgẹbi awọn toasters ati awọn igbona alapapo itanna miiran ṣe lilo awọn alloys nickel-chromium.Nigbati a ba ṣejade ni fọọmu waya wọn jẹ mọ bi okun waya Nichrome®.
