5 Zvinhu zvinokanganisa kuyerwa kusava nechokwadi

5.1 Coating ukobvu

Chiyero chekusava nechokwadi chiripo mune iyo nzira. Kune machira akaonda, uku kusava nechokwadi kwechiyero (mumashoko akakwana) anogara, akazvimirira kubva pakukora uye, pachiyero chimwe chete, inosvika 0,5μm. Kune machira akakora kupfuura 25 μm, kusavimbika kunova kunoenderana nekukora uye kunenge chidimbu chinogara chiripo cheukobvu ihwohwo.

Pakuyera ukobvu hwejasi hwe5 μm kana pasi, avhareji yevanomweral zviyero zvichatorwa.

Zvingave zvisingakwanisi kuwana kuyerwa kwekusavimbika kwakatsanangurwa muChikamu 8 pakuyera machira ari pasi pe3 μm mukukora.

5.2 Magetsi zvimiro zvehwaro zvinhu

Zviyero zvinoshandisa eddy ikozvino zviridzwa zvinogona kukanganiswa nemagetsi conductivity yenheyo yesimbi, iyo ibasa rekuumbwa uye kupisa kwekupisa kwezvinhu. Kufurira kwemagetsi conductivity pachiyero kunosiyana zvakanyanya nekugadzira uye rudzi rwechiridzwa.

5.3 Nheyo yesimbi ukobvu

Pachiridzwa chega chega pane yakakosha hwaro hwesimbi ukobvu pamusoro peiyo zviyero hazvikanganisike nekuwedzera kwehukobvu. Sezvo ukobvu uhwu hunoenderana nezvose zviri zviviri eddy yazvino chizvarwa frequency yeprobe system uye zvemagetsi zvimiro zvehwaro hwezvinhu kukosha kwayo kunofanirwa kutariswa kuyedza, kunze kwekunge yatsanangurwa neimwe nzira nemugadziri.

Tsananguro yechizvarwa chazvino cheEddy uye kuverenga kweiyo yakaderera base base materia ukobvu, dmin, inopihwa muAnnex A.

Zvakadaro, pakashaikwa chero rumwe ruzivo, hudiki hunodiwa hwaro hwezvinhu ukobvu, dmin, hunogona kufungidzirwa kubva paequation:dmin = 2,5 δ0 apo δ0 ndiyo yakajairwa kudzika kweiyo nheyo yezvinhu (ona A.1).

5.4 Edge mhedzisiro

Eddy zvazvino zviridzwa zvinogona kuve nehanya nekuchimbidza shanduko mune yepasi contour yebvunzo specimen. Naizvozvo kuyerwa kwakaitwa pedyo nekumucheto kana kona kunogona kusashanda kunze kwekunge chiridzwa chacho chanyatsogadziriswa zviyero zvakadaro (ona 6.2.4 uye Annex B).

CHERECHEDZA Kana uchienzaniswa neiyo phase-sensitive nzira yeISO 21968, iyo amplitude-sensitive eddy ikozvino zviridzwa inogona kunyanya kukanganiswa nemhedzisiro.

5.5 Surface curvature

Zviyero zvinokanganiswa nekukombama kweyeyedzo specimen. Iyi pesvedzero yecurvature inosiyana zvakanyanya nekugadzirwa uye rudzi rwechiridzwa uye probe, asi inogara ichinyanya kutaurwa sezvo radius ye curvature inodzikira. Zviyero zvinogadzirwa pazviyero zvakakombama bvunzo zvinogona kusashanda, kunze kwekunge chiridzwa chakanyatso kurongedzerwa iyo yepamusoro curvature iri mubvunzo, kana yakakosha probe, inotsiva pesvedzero yepasi, inoshandiswa.

5.6 Kushata kwepamusoro

Zviyero zvinopesvedzerwa nepamusoro petopography yehwaro hwezvinhu uye yekupfeka. Nzvimbo dzakakasharara dzinogona kukonzera zvese zvakarongwa uye zvisina tsarukano kukanganisa. Zvikanganiso zvisingaite zvinogona kudzikiswa nekuita kuyerwa kwakawanda, kuyerwa kwega kwega kuchiitwa pane imwe nzvimbo, uyezve kuverenga kukosha kweavhareji yezviyero zvakatevedzana.

Kana hwaro hwezvinhu hwakakasharara, zero yechiridzwa ichatariswa pamaseveral nzvimbo pane yakajairwa sample yeisina kuvharwa, rough, hwaro hwezvinhu. Kana pasina yakajairwa isina kuvharwa hwaro hwezvinhu iripo, iyo yekuvharisa yeyeyedzo sampuli ichabviswa, zvirinani pamusoro pechikamu chenzvimbo yayo, nemakemikari mhinduro isingarwise hwaro hwezvinhu.

CHERECHEDZA Kana uchienzaniswa neiyo phase-sensitive nzira yeISO 21968, iyo amplitude-sensitive eddy yazvino kuyerwa kunogona kukanganiswa zvakanyanya nehwaro hwezvinhu roughness.

5.7 Lift-off effect

Kana iyo probe isina kuiswa zvakananga pamucheka, mukaha pakati peprobe uye kupfeka ("kusimudza-kure") inokanganisa kuyerwa kwehuputi hwehuputi. Ukobvu hwakayerwa huchaenzana nehupamhi hwekuputira pamwe nekuwedzera "kusimudza-kubvisa" gap.Kusimudza-kure kunogona kugadzirwa nekusaziva, semuenzaniso, nekuvapo kwezvimedu zvekunze pakati peprobe nejira. kuitira utsanana.

5.8 Probe pressure

Kudzvinyirirwa uko probe inoshandiswa kumuenzaniso wekuedza inokanganisa kuverenga kwechiridzwa uye naizvozvo ichaitwa nguva dzose.Iyi mhepo inodzvinyirira inonyanya kuonekwa kana machira ari munyoro. Midziyo mizhinji inotengeswa inopihwa inogara ichidzvanywa probes.

5.9 Probe tilt

Kunze kwekunge zvarairwa nemugadziri, probe ichashandiswa perpendicularly kune yakavhara pamusoro sezvo kurerekera probe kure neperpendicular kunogona kukonzera kuyerwa kukanganisa.Mukana wekurerekera kuitika nekusaziva unogona kudzikiswa nekugadzira probe kana nekushandisa probe- vakabata jig.

5.10 Tembiricha mhedzisiro

Nekuti shanduko yetembiricha inokanganisa hunhu hweprobe, inofanirwa kushandiswa pasi pemamiriro etembiricha akafanana neaya anoshandiswa pakugadzirisa kunze kwekunge probe yakagadzirisa muripo wetembiricha.

5.11 Kupfeka kwepakati

Kuvapo kwejasi repakati kunogona kukanganisa kuyerwa kwehuputi hwehuputi kana maitiro emagetsi eiyo yepakati coating achisiyana kubva kune iyo yekupfeka kana hwaro zvinhu. Kana mutsauko uripo saka zviyero zvinozove, nekuwedzera, zvinokanganiswa nepakati coating ukobvu hweisingasviki dmin. Kana ukobvu hwakakura kupfuura dmin saka iyo yepakati coating, kana isiri-magnetic, inogona kubatwa seyakavakirwa zvinhu.Zvakaonekwa kuti zvimwe zviridzwa zvine probe masisitimu anoshanda neakawanda mafrequency anogona kuyera ese epamusoro uye epakati coatings.
