Kungani kunamabhamuza ezindaweni zokushisela zomshini wokushisela amabala aphakathi nendawo? Ukwakhiwa kwama-bubbles kuqala kudinga ukwakheka kwe-bubble core, okumele ihlangabezane nemibandela emibili: enye iwukuthi insimbi ewuketshezi 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 ahlinzekwe ukwenza amandla enuzi. Ngokusobala, lapho amandla e-nucleation ephakama, mancane amathuba okuba enze umnyombo webhamuza. Ngokuphambene, kuba lula ukwakha i-bubble core.
