awad k, young s, aswath p, varanasi v: interfacial adhesion and surface bioactivity of anodized titanium modified with sion and
Katyanochek1 [597]

Interfacial adhesion and surface bioactivity of anodized titanium modified with SiON and SiONP surface coatings, The statement is correct.

<h3>what is adhesion ?</h3>

Adhesion is a type of attraction between two dissimilar phases, the theory of adhesion can be up two types mechanical interlocking and physical and chemical bonding and it is a combination of three methods.

Mechanical interlocking means when two dissimilar phases interact with  one another by mechanical forces, requires a rough surface where the other material can enter.

Physical bonding includes van der Waals forces and the strength  is rather weak and unable to contribute that much bonding strength.

Chemical bonding consist of covalent, ionic and metallic bonding which are more stronger than physical bonds and are responsible for cohesive forces.

chemical bonding between two dissimilar materials is  more complicated due to the presence of few available bonding sites.
