Kungani kunamabhamuza ezindaweni zokushisela zomshini wokushisela amabala aphakathi nendawo?Ukwakhiwa kwama-bubbles kuqala kudinga ukwakheka kwe-bubble core, okumele ihlangabezane nezimo ezimbili: enye iwukuthi insimbi ye-liquid inegesi ephezulu, kanti enye inamandla adingekayo ukuze i-nucleation.Ukuhlaziywa kanye nezixazululo zenkinga yamabhamuza ahlangene we-solder:
I-supersaturation ensimbi ye-liquid iphakeme ngokuqhathaniswa, futhi ukuphakama kwe-supersaturation, kuba nokungazinzi kakhulu.Igesi cishe izona futhi yakhe amabhamuza.Ngakho-ke, ichibi elincibilikisiwe ekushiseleni linezimo ezidingekayo ze-supersaturation ukwenza ama-bubbles.Njengenqubo ye-metal crystallization, i-bubble nucleation ingenzeka ngezindlela ezimbili: i-nucleation ezenzakalelayo kanye ne-nucleation engavamile.Uma i-bubble core yakheka, ibhamuza kufanele linqobe ukucindezela koketshezi futhi lenze umsebenzi wokunweba
Ngenxa yokwanda kwamandla angaphezulu okubangelwa ukwakheka kwezigaba ezintsha, uma i-bubble core enosayizi obalulekile kwakheka oketshezini, amandla anele kufanele anikezwe ukwenza amandla enuzi.Ngokusobala, lapho amandla e-nucleation ephakama, mancane amathuba okuba enze umnyombo webhamuza.Ngakolunye uhlangothi, kuba lula ukwenza i-bubble core.
