Izimbangela kanye Nokuthuthukiswa Kokucwecwa kanye Nokuchotshozwa Kwephrofayili Ye-Inner Cavity of Cavity

1 Incazelo yezenzakalo zokukhubazeka

Lapho ukhipha amaphrofayili we-cavity, ikhanda lihlala liklwejwa, futhi izinga elingasebenzi kahle licishe libe ngu-100%. Umumo ojwayelekile onesici wephrofayili umi kanje:

2 Ukuhlaziya kokuqala

2.1 Uma ubheka indawo yesici kanye nokuma kwesici, i-delamination kanye nokuxebuka.

2.2 Imbangela: Ngenxa yokuthi isikhumba sentonga yokubungula yangaphambili sasigoqelwe esikhaleni sesikhunta, ukungafani, ukuxebuka, nezinto ezibolile zavela ekhanda elikhiphayo lenduku yokuphonsa elandelayo.

3 Ukutholwa nokuhlaziya

Ukuskena kwe-electronic microscope yokukhulisa okuphansi, ukukhuliswa okuphezulu kanye nokukhubazeka kwesigaba esiphambanayo senduku yokuphonsa kwenziwa ngokulandelanayo.

3.1 Induku yokuphonsa ukukhuliswa okuphansi

11 inch 6060 casting induku yokukhulisa okuphansi Ukuhlukaniswa kobuso 6.08mm

3.2 Induku yokuphonsa ukukhuliswa okuphezulu

Eduze kwendawo yomugqa wokuhlukanisa isendlalelo se-epidermis

Induku yokuphonsa 1/2 isikhundla

3.3 Ukuskena amaphutha ngesibonakhulu se-electron

Khulisa indawo enesici izikhathi ezingama-200

Umdwebo we-spectrum yamandla

Ukuhlaziywa kwengxenye ye-EDS

4 Incazelo emfushane yemiphumela yokuhlaziya

4.1 Ungqimba oluwugqinsi oluyi-6mm lokuhlukanisa luvela endaweni ekhulisa kancane yenduku yokuphonsa. Ukuhlukaniswa kuyi-eutectic ye-low-melting-point, ebangelwa ukupholisa kancane kokusakazwa. Ukubukeka kwe-macroscopic kumhlophe futhi kuyacwebezela, futhi umngcele one-matrix ucacile;

4.2 Ukukhulisa okuphezulu kukhombisa ukuthi kunezimbotshana onqenqemeni lwenduku yokuphonsa, okubonisa ukuthi amandla okupholisa aphakeme kakhulu futhi uketshezi lwe-aluminium aluphakelwa ngokwanele. Ku-interface phakathi kwesendlalelo sokuhlukanisa kanye ne-matrix, isigaba sesibili asivamile kakhulu futhi asiqhubeki, okuyindawo empofu kakhulu. Ububanzi benduku yokuphonsa yi-1/2 Ukuba khona kwama-dendrites endaweni kanye nokusatshalaliswa okungalingani kwezingxenye kuphinde kubonise ukuhlukaniswa kwesendlalelo esingaphezulu kanye nezimo zokukhula kokuqondisa kwama-dendrites;

4.3 Isithombe sesici esiphambanayo emkhakheni we-200x wokubuka isibonakhulu se-electron sibonisa ukuthi indawo ilukhuni lapho isikhumba sixebuka khona, futhi ingaphezulu libushelelezi lapho isikhumba singaxebuki. Ngemva kokuhlaziywa kokwakheka kwe-EDS, amaphuzu 1, 2, 3, kanye ne-6 yizindawo ezinesici, futhi ukwakheka kuqukethe i-C1, K, kanye ne-Na yizici ezintathu, okubonisa ukuthi kukhona ingxenye ye-ejenti yokucwenga ekubunjweni;

4.4 Izingxenye C kanye no-0 ezingxenyeni ezisemaphoyintini 1, 2, no-6 ziphakeme, futhi izingxenye ze-Mg, Si, Cu, no-Fe endaweni yesi-2 ziphakeme kakhulu kunalezo ezikumaphuzu 1 no-6, okubonisa ukuthi ukwakheka kwe indawo enesici ayilingani futhi kukhona ukungcola okungaphezulu okuhilelekile;

I-4.5 Yenza ukuhlaziywa kwengxenye kumaphuzu we-2 no-3 futhi yathola ukuthi izingxenye ziqukethe isici se-Ca, okubonisa ukuthi i-talcum powder kungenzeka ukuthi ihileleke ebusweni benduku ye-aluminium ngesikhathi senqubo yokukhipha.

5 Isifinyezo

Ngemuva kokuhlaziywa okungenhla, kungase kubonakale ukuthi ngenxa yokuba khona kokuhlukaniswa, i-ejenti yokuhlanza, i-talcum powder kanye ne-slag inclusions ebusweni benduku ye-aluminium, ukwakheka akulingani, futhi isikhumba sigoqwe emgodini wesikhunta ngesikhathi sokukhipha, okubangela ukuxebuka ekhanda. Ngokunciphisa izinga lokushisa lenduku yokuphonsa kanye nokuqina kokuqina okusele, izinkinga zokucwecwa nokuchotshozwa zingancishiswa noma zixazululwe; isilinganiso esiphumelela kakhulu ukwengeza umshini wokucwecwa wokucwecwa nokukhipha.
