After coming into contact, a chemical bond is formed between parts of the two surfaces, called adhesion, and charges move from one material to the other to equalize their electrochemical potential.
Logo de entrar en contacto, un vínculo químico fórmase entre algunhas partes das dúas superficies, chamado adherencia, e as cargas móvense a partir dun material ao outro para igualar o seu potencial electroquímico.
