Cov khoom siv NiCr, luv rau nickel-chromium alloy, yog cov khoom siv ntau yam thiab ua tau zoo heev rau nws qhov kev sib xyaw ua ke ntawm kev tiv taus cua sov, kev tiv taus corrosion, thiab kev ua hluav taws xob. Ua los ntawm nickel (feem ntau 60-80%) thiab chromium (10-30%), nrog rau cov ntsiab lus xws li hlau, silicon, lossis manganese los txhim kho cov khoom tshwj xeeb,Cov hlau NiCrtau dhau los ua qhov tseem ceeb hauv kev lag luam xws li aerospace mus rau electronics - thiab peb cov khoom NiCr tau tsim los siv cov zog no kom tag nrho.

Lub hauv paus ntawm NiCr qhov kev thov yog nws qhov kev ruaj khov zoo heev thaum kub. Tsis zoo li ntau yam hlau uas mos lossis oxidize thaum raug cua sov heev, NiCr alloys tswj lawv lub zog kho tshuab thiab kev ua haujlwm zoo txawm tias kub tshaj 1,000 ° C. Qhov no yog vim muaj cov ntsiab lus chromium, uas tsim cov txheej txheem oxide ntom ntom, tiv thaiv ntawm qhov chaw, tiv thaiv kev oxidation thiab kev puas tsuaj ntxiv. Qhov no ua rau NiCr zoo tagnrho rau cov ntawv thov xws li cov khoom cua sov cua sov, cov khoom siv cav dav hlau, thiab cov kilns kev lag luam, qhov twg kev raug cua sov siab tsis zam.

Kev tiv thaiv xeb yog lwm yam tseem ceeb. NiCr alloys zoo heev hauv kev tiv thaiv kev tawm tsam los ntawm cov chaw oxidizing, suav nrog huab cua, pa, thiab qee yam tshuaj lom neeg. Cov cuab yeej no ua rau lawv muaj txiaj ntsig zoo hauv cov nroj tsuag ua tshuaj lom neeg, qhov chaw uas lawv siv rau hauv cov cua sov sib pauv, reactors, thiab cov kav dej uas tswj cov xov xwm corrosive. Tsis zoo li cov hlau ntshiab lossis cov hlau tsis muaj zog, NiCr cov ntaub ntawv tiv thaiv pitting, scaling, thiab xeb, ua kom ntseeg tau tias muaj kev ntseeg siab mus sij hawm ntev thiab txo cov nqi txij nkawm.

Kev ua hluav taws xob conductivity yog qhov tseem ceeb thib peb. Txawm hais tias tsis conductive zoo li tooj liab ntshiab, NiCr alloys muab qhov sib npaug tshwj xeeb ntawm conductivity thiab tiv taus cua sov, ua rau lawv zoo meej rau cov khoom siv cua sov hauv cov khoom siv, cov cua sov kev lag luam, thiab cov hluav taws xob resistors. Lawv lub peev xwm los tsim thiab faib cua sov sib npaug yam tsis muaj kev puas tsuaj ua kom muaj kev ua tau zoo hauv cov khoom siv xws li toasters, cov plaub hau dryers, thiab cov qhov cub kev lag luam.

Peb cov khoom NiCr yog tsim los kom ua kom tau qhov zoo tshaj plaws no. Peb muaj ntau yam qauv, los ntawm cov hlau nickel siab rau kev tiv taus cua sov heev rau cov chromium-nplua nuj variants optimized rau kev tiv thaiv xeb. Muaj nyob rau hauv cov ntaub ntawv xws li cov xov hlau, ribbons, ntawv, thiab cov khoom tshwj xeeb, peb cov khoom yog precision-manufactured siv cov txheej txheem siab heev kom ntseeg tau tias muaj cov khoom sib xws thiab qhov tseeb. Kev kuaj xyuas zoo nruj lav tias txhua daim ua tau raws li cov qauv kev lag luam, txawm tias rau cov khoom siv aerospace-qib lossis cov khoom siv cua sov txhua hnub.

Txawm koj xav tau cov khoom siv uas tuaj yeem tiv taus qhov nyuaj ntawm cov txheej txheem kev lag luam kub siab lossis tiv taus xeb hauv cov chaw muaj tshuaj lom neeg hnyav,Peb cov khoom NiCrxa cov kev ua tau zoo thiab kev ruaj khov uas koj ntseeg siab tau. Nrog rau cov kev daws teeb meem rau ntau yam kev siv, peb cog lus tias yuav muab cov ntaub ntawv NiCr uas ua rau koj cov haujlwm ua haujlwm tau zoo thiab ntev dua.
