Zvinokonzeresa uye Kuvandudzwa kwePeeling uye Kupwanya kweInner Cavity yeCavity Profiles.

1 Tsanangudzo yezvakaremara zviitiko

Paunenge uchiwedzera maprofiles, musoro unogara uchikweshwa, uye chiyero chakakanganisika chinenge 100%. Iyo yakajairika yakaremara chimiro cheiyo mbiri ndeiyi inotevera:

2 Kuongorora kwekutanga

2.1 Tichitarisa kubva panzvimbo yechirema uye chimiro chechikanganiso, iri delamination uye peeling.

2.2 Chikonzero: Nekuda kwekuti ganda retsvimbo yekukanda yakapfuura yakakungurutswa mugomba, kusapindirana, kusvuura, uye zvinhu zvakaora zvakaonekwa kumusoro kwekuburitsa kweinotevera tsvimbo yekukanda.

3 Kuona uye kuongorora

Electron microscope scans yeakadzika magnification, kukwidziridzwa kwepamusoro uye kukanganiswa kwechikamu-chikamu chetsvimbo yekukanda yakaitwa zvichiteerana.

3.1 Kukanda tsvimbo yakaderera kukura

11 inch 6060 kukanda tsvimbo yakaderera magnification Surface segregation 6.08mm

3.2 Kukanda tsvimbo kukwidziridzwa kwepamusoro

Pedyo neiyo epidermis Segregation layer yekukamura mutsara nzvimbo

Kukanda tsvimbo 1/2 chinzvimbo

3.3 Electron microscope scanning yezvakaremara

Wedzera nzvimbo yakakanganiswa ka200

4 Tsanangudzo pfupi yemhedzisiro yekuongorora

4.1 A 6mm gobvu segregation layer inoonekwa pane yakaderera-magnification pamusoro peiyo yekukanda tsvimbo. Iyo yekuparadzanisa ndeye yakaderera-melting-point eutectic, inokonzerwa nekutonhora kwekukanda. Chimiro che macroscopic chichena uye chinopenya, uye muganhu une matrix wakajeka;

4.2 Kukwidziridzwa kwepamusoro kunoratidza kuti kune pores kumucheto kwedanda rekukanda, zvichiratidza kuti kutonhora kwakanyanya kwakanyanya uye mvura yealuminium haina kudyiswa zvakakwana. Pachiratidziro pakati pekuparadzanisa layer uye matrix, chikamu chechipiri hachiwanzoitiki uye chinopera, iyo inzvimbo ine solute-varombo. Iyo dhayamita yetsvimbo yekukanda ndeye 1/2 Kuvapo kwe dendrites panzvimbo uye kugoverwa kusina kuenzana kwezvikamu kunowedzera kuratidza kuparadzaniswa kwepamusoro pepamusoro uye mamiriro ekukura kwekutungamira kwe dendrites;

4.3 Mufananidzo wekukanganisa kwechikamu chechikamu che200x yekuona kweelectron microscope scan inoratidza kuti pasi pakashata panosvuuka ganda, uye pamusoro pacho pakatsetseka apo ganda risiri kusvuuka. Mushure mekuongorora kwe EDS kuumbwa, pfungwa 1, 2, 3, uye 6 inzvimbo dzakaremara, uye kuumbwa kunosanganisira C1, K, uye Na zvinhu zvitatu, zvichiratidza kuti kune chikamu chekugadzirisa mumiririri;

4.4 Zvikamu zveC uye 0 muzvikamu pazvikamu 1, 2, uye 6 zvakakwirira, uye Mg, Si, Cu, uye Fe zvikamu panzvimbo 2 zvakakwirira kudarika izvo zviri pamapoinzi 1 ne6, zvichiratidza kuti kuumbwa kwe nzvimbo yakakanganisika haina kuenzana uye pane kusvibiswa kwepamusoro kunobatanidzwa;

4.5 Yakagadzirisa chikamu chekuongorora pane pfungwa 2 uye 3 uye yakawana kuti zvikamu zvine Ca element, zvichiratidza kuti talcum powder inogona kunge yakabatanidzwa pamusoro pesimbi yealuminium panguva yekukanda.

5 Pfupiso

Mushure mekuongorora kwepamusoro, zvinogona kuonekwa kuti nekuda kwekuvapo kwekuparadzanisa, kuchenesa, talcum powder uye slag inclusions pamusoro pesimbi yealuminium, kuumbwa hakuna kuenzana, uye ganda rinoputirwa mumugodhi panguva ye extrusion, kukonzeresa kusvuuka kwemusoro. Nekudzikisa tembiricha yetsvimbo yekukanda uye kuomesa iyo yakasara ukobvu, iyo peeling uye kupwanya matambudziko anogona kuderedzwa kana kutogadziriswa; chiyero chinonyanya kushanda ndechekuwedzera muchina wekupenyura wekusvuura uye extrusion.
