Adhesion
Adhesionis the process in which dissimilarparticlesstick together. In the case of similar particles, this effect is calledcohesion.Adhesion results from the physical properties of theinterfacebetween twophases.The forces that result in adhesion are not fully known, there are different explanations. Five different types of adhesion have been proposed:
- Mechanical adhesion: Adhesive materials fill the voids or pores, and interlock
- Chemical adhesion: Where they join, two materials form aChemical compound.
- Dispersive adhesion: Two materials are held together byVan der Waals forces
- Electrostatic adhesion: Two materials are held together byelectrostatic charge
- Diffusive adhesion: Two materials are held together withAtomic diffusion,it is derived from a sanskrit word adhere meaning to hold on
