reacts explosively on contact with liquid oxygen ; under normal conditions, however, aluminium forms a thin oxide layer that protects the metal from further corrosion by oxygen, water, or dilute acid, a process termed passivation . [ ] [ ] because of its general resistance to corrosion, aluminium is...
the matrix is ductile, it prevents propagation of cracks between fibres or particles, even when it is subjected to hard wear. the size and shape of the particles and fibres of the dispersed phase govern how closely they can be packed. although smaller particles provide more surface area for contact with...
