Kev txiav txim siab qib ntawm corrosion nyob rau hauv honeycomb core cov ntaub ntawv nyob ntawm seb hom, qhov chaw, thiab cov khoom ntawm corrosion. Ntawm no yog ib qho kev tawg ntawm cov tshuaj meth
Deg Corrosion: Aluminium honeycombs qhia pitting, dawb me ntsis, los yog tev; aramid honeycombs darken xim thiab ua nkig.
Electrochemical Corrosion: Feem ntau hnyav thaum txhuas honeycombs nyob rau hauv kev sib cuag nrog carbon fiber panels, manifests li corrosion pits los yog electrolyte kab nyob rau hauv lub honeycomb hlwb.
Interface Corrosion: tshwm sim ntawm qhov sib txuas ntawm cov khoom siv tseem ceeb thiab lub vaj huam sib luag, ua rau delamination thiab blistering, feem ntau ua rau kev ua haujlwm tsis zoo.
Kev tshuaj xyuas qhov muag: Saib xyuas cov xim hloov, pwm me ntsis, blistering, los yog hmoov.
Dimensional Measurement: Ntsuas lub thickness nrog calipers thiab muab piv rau tus nqi qub los txiav txim siab compression deformation.
Impact Test: Mloog cov kev hloov ntawm lub suab; Hollow los yog dull suab yuav qhia tau hais tias sab hauv corrosion los yog delamination.
Tsis yog-Kev kuaj kev puas tsuaj: Ultrasonic C-scanning lossis X-ray tsis pom kev tuaj yeem txheeb xyuas qhov tob thiab qhov tob ntawm corrosion.
Laboratory Analysis: Corrosion rate yog ntsuas los ntawm txoj kev gravimetric, thiab oxide zaj duab xis hla -section tau soj ntsuam los ntawm scanning electron microscopy.
Cov khoom sib txawv
Aluminium Honeycomb: Yooj yim rau pitting thiab electrochemical corrosion; xyuam xim rau corrosion pits ntawm pore npoo.
Aramid Honeycomb: Resistant rau tshuaj corrosion, tab sis cov fibers yuav dhau los ua embrittled vim ultraviolet hluav taws xob los yog ya raws.
Daim Ntawv Honeycomb: Feem ntau raug rau cov dej noo; corrosion manifests raws li pwm loj hlob thiab tsis muaj zog.
