Izimbangela kanye nokwenza ngcono ukubhebhana nokuchotshozwa kwe-cavity yangaphakathi yamaphrofayili e-cavity

1 Ukuchazwa kwe-Defect Phenomena

Lapho ukhipha amaphrofayili e-cavity, ikhanda lihlala liklwebekile, futhi izinga elinephutha licishe libe yi-100%. Isimo esijwayelekile esingonakalo sephrofayili sinje:

Ukuhlaziywa kokuqala

2.1 Ukwahlulela kusuka endaweni yesiphene kanye nokwakheka kwesici, kuwukuhlehlisa futhi kubhebha.

2.2 Imbangela: Ngoba isikhumba senduku yokuphonsa kwangaphambilini sasigibela emgodini womuntu, ukungahambi kahle, ukuncipha kanye nemininingwane ebolile kwavela ekhanda lenduku elandelayo yenduku.

Ukutholwa nokuhlaziywa

Ukuskena kwe-MicrotroncroPope kokukhulisa okuphansi, ukukhuliswa okuphezulu kanye neziphambeko zesigaba sesigaba senduku yokuphonsa kwenziwa ngokulandelana.

3.1 Ukuphonsa induku yokukhulisa okuphansi

11 inch 6060

3.2 Ukuphonsa induku enkulu kakhulu

Eduze ne-epidermis sergrer ungqimba ehlukanisa umugqa wendawo

Ukuphonsa induku 1/2 isikhundla

3.3 Ukuskena kwe-Microtro Microscope of Defles

Khulisa I-Decect Indawo izikhathi ezingama-200

Umdwebo we-Energy Spectrum

Ukuhlaziywa kwengxenye ye-EDS

4 Incazelo emfushane yemiphumela yokuhlaziywa

4.1 Ungqimba olungama-6mm oluwugqinsi olungama-6mm luvela ebusweni obuphansi bokukhulisa induku. Ukuhlukaniswa kwe-eupectic enendawo ephansi, okubangelwa ukubekelwa phansi kokuphola. Ukubukeka kwe-macroscopic kumhlophe futhi kucwebezela, futhi umngcele kanye ne-matrix ucacile;

4.2 Ukukhulisa okuphezulu kukhombisa ukuthi kukhona ama-pores onqenqemeni lwenduku yokuphonsa, ekhombisa ukuthi ukuqina okupholile kuphezulu kakhulu futhi uketshezi lwe-aluminium alondli ngokwanele. Esibonelweni phakathi kwesendlalelo sokwehlukaniswa kanye ne-matrix, isigaba sesibili asivamile kakhulu futhi sinqabile, okuyindawo empofu. Ububanzi benduku yokuphonsa buyi-1/2 ukuba khona kwama-dendrites endaweni kanye nokusatshalaliswa okungalingani kwezakhi kukhombisa ukuhlukaniswa kongqimba olungaphezulu nemibandela yokukhula okuqondayo kwama-dendrites;

4.3 Isithombe sesiphephelo sesiphambano esigabeni se-200x yokubukwa kwesimanga se-elektroni sibonisa ukuthi ingaphezulu liyakhamba lapho isikhumba sikhonkotha khona, futhi ingaphezulu libushelelezi lapho isikhumba singakhonjiswa khona. Ngemuva kokuhlaziywa kokuhlaziywa kwe-EDS, amaphuzu 1, 2, 3, no-6 yizindawo eziphikisayo, futhi ukwakheka kuqukethe i-C1, K, ne-NA kuyizinto ezintathu, okubonisa ukuthi kunengxenye ecwengekileyo ekwakhiweni;

4.4 Izingxenye ze-C ne-0 ezingxenyeni zamaphuzu 1, 2, no-6 ziphakeme, kanye ne-MG, SI, CU, kanye neFe Izakhi ePhoyinti 2 no-6, okukhombisa ukuthi ukwakheka kwe Indawo yokulimala ayilingani futhi kukhona ukungcola komhlaba okubandakanyekayo;

4.5 Ukuhlaziywa Kwezakhi Ezihlanganisiwe Ngamaphuzu 2 no-3 futhi kutholakale ukuthi izakhi eziqukethe into ethize ye-CA, okukhombisa ukuthi kungenzeka ukuthi i-talcum powder ibandakanyeke ebusweni benduku ye-aluminium ngesikhathi senqubo yokuphonsa.

Okufingqiwe

Ngemuva kokuhlaziywa okungenhla, kungabonakala ukuthi ngenxa yokuba khona kokwehlukaniswa, ukucwilisa i-ejenti, i-talcum powder kanye ne-slag inclusions ebusweni benduku ye-aluminium, futhi ukwakheka kudluliselwe emgodini wokudala, kubangela isici sokukhonkotha ekhanda. Ngokwehlisa izinga lokushisa lenduku yokuphonsa futhi agqitshwe ubukhulu obusalayo, izinkinga ezibucayi kanye nezinkinga zokuchotshozwa zingancishiswa noma zixazululwe; Isinyathelo esisebenza kakhulu ukwengeza umshini wokukhonkotha ukuze ubheke nokukhishwa.
