Hlinik v solnom roztoku nekoroduje, ani cisty .. hlinik sa pokryva tenkou antikoroznou vrstvou pri kontakte so vzduchom .. problem je inde

Salt water DOES NOT corrode aluminum! You may have noticed that you never see aluminum corrosion in lakes, pools, food packaging products, etc ..
Problem je pravdepodobne toto:
When the two dissimilar metals come into contact, the electrical loop is closed, and the natural voltage differential between them causes electron flow. One metal will become the anode (negative) and one will become the cathode (positive).In the simplest terms, this electrical circuit causes the anode to lose ions and the cathode to gain ions. his process slowly consumes the anode (galvanic or dissimilar metal corrosion) and effectively strengthens the cathode gainst corrosion.
Ale v konecnom dosledku je posypova sol zrejme pricinou
, len dovod je malinko iny .. co ale je vlastne jedno. Aj ked .. mozno pri pouziti ocelovych niplov toto problem nebude. Asi preto s kolesami problem nemam ani po 3 zimach. Kua, ale tuto zimu jazdim na alu niploch , ajaj
