Question

is mechanical bond a weak bond? means what type of bonding is mechanical bonding?

Answer 1

Mechanical bonding is a kind of chemical bond that is usually found in rotaxanes and catenanes or other molecular structures that are mechanically interlocked. In this type of adhesive bonding, the adhesive material locks physically onto the surface crevices.

Mechanical bonding is applied in industrial materials in order to improve strength, making materials more resistant to damage and corrosive effects.
