Unobangela kunye nokuphuculwa kokutyibilikiswa kunye nokutyumza kwe-cavity engaphakathi yeeprofayili ze-cavity

1 Inkcazo ye-DHOmena

Xa i-Suplor Privering Failings, intloko isoloko ikrwada, kwaye inqanaba elinesiphene liphantse laba yi-100%. Ubume obuqhelekileyo obunesiphene zeprofayile zezi zilandelayo:

2 Uhlalutyo lwangaphambili

2.1 Ukugweba ukusuka kwindawo esiphene kunye nobume besiphene, kuyabaziswa kwaye kugqityiwe.

2.2 Unobangela: Ngenxa yokuba ulusu lwentonga yokuphosa yangaphambili yaqengqeleka kwi-coldn cavity, i-mismatch, i-peling, kunye nezinto ezibolileyo zavela kwintloko yentonga elandelayo.

Ukufunyanwa kwe-3 kunye nohlalutyo

I-microscope ye-elektroniki ye-Electroni yokuphumeza okuphantsi, ukwenziwa kokuphakama okuphezulu kunye neziphene zecandelo lentonga yokuphoswa kwaqhutywa ngokulandelelana.

3.1 Ukuphosa i-rod yokukhulisa

I-11 intshi yama-6060 yokuphosa i-rod ye-rod ye-rapreation ephezulu ye-6.08mm

3.2 Ukuphosa iDolophu ephezulu

Kufutshane ne-epiderming readreation eyahlula indawo yendawo

Ukuphosa iRoD 1/2 isikhundla

3.3 Ukuskena kwe-elektroniki ye-microscope yeziphene

Yandisa indawo yesiphene amaxesha angama-200

Umzobo we-Spectrum yamandla

Uhlalutyo lwecandelo le-EDS

4 Inkcazo emfutshane yeziphumo zohlalutyo

4.1 I-6mm i-6mm yoqondakala ivela kumphezulu ophantsi wentonga yentonga yokuphosa. I-disgregation yindawo elula yokunyibilika, ebangelwa kukungcungcutheka kokuphosa. Inkangeleko ye-macroscopic imhlophe kwaye icwebekile, kwaye umda kunye neMatrix icacile;

4.2 Ukuqina okuphezulu kubonisa ukuba kukho iipores kumda wentonga yokuphosa, ebonisa ukuba ubunzulu bokupholisa bukhulu kakhulu kwaye ulwelo lwe-aluminium alondliwe ngokwaneleyo. Kwindawo ephakathi komaleko wengqokelela kunye ne-matrix, iSigaba sesibini inqabile kwaye iyekisiwe, eyindawo elula. Ububanzi bentonga yokuphosa yi-1/2 ubukho bendawo kunye nokusasazwa kwezinto ezingalinganiyo kubonisa ngakumbi ukwahlukana komgangatho kunye neemeko zokukhula kwezikhokelo;

4.3 Ifoto yesiphene esinqamlezayo kwicandelo le-200x lemifanekiso ye-Electroni ibonisa ukuba umphezulu oqingqiweyo apho ulusu lungasebenzi apho ulusu lungakhathali. Emva kohlalutyo lwe-EDS, amanqaku 1, 2, 3, kunye ne-6 iindawo ezinesiphene, kwaye ukwakhiwa kuqulatha i-C1, k, kunye ne-NA, kwaye kukho into ephikisayo yearhente yokwakha;

4.4 I-C kunye ne-0 yezinto ezikwiingxowa-1, 2, kunye ne-6 ziphezulu, kwaye i-MG, i-CU, i-CU, i-cu, i-FU, kunye ne-FRE, i-6, ibonisa ukuba ukwakhiwa kwe Indawo yesiphene ayihambelani kwaye kukho ukungcola okungaphezulu kubandakanya;

4.5 Uhlalutyo lwecandelo kwi-POPS 2 ne-3 kwaye yafumanisa ukuba izinto zinezinto ze-CO, zibonisa ukuba i-talcum powder inokubandakanyeka kumphezulu wenkqubo yokuphosa.

5 Isishwankathelo

Emva kohlalutyo olungasentla, lunokubonwa ukuba ubukho bendawo yokwahlula, iarhente ehlaziyiweyo, i-Talcum Powder kunye ne-Slag iqukuthezi kumphezulu we-aluminium, kwaye ulusu luye lwangena kwi-onlimosion, ebangela isiphene esinesiphene entloko. Ngokuthoba ubushushu bentonga yokuphosa kwaye kukutyibilika kubunzima bentsalela, iingxaki ezityebileyo kunye nokutyumza zinokuncitshiswa okanye zisonjululwe; Elona nqanaba lisebenzayo longeza umatshini oqingqiweyo wokuthambisa kunye nokuphuma.
