Biomaterials - Quiz 2
Terms in this set (13)
The zone where the structure and composition (influenced by the interface) differs from the average bulk composition and structure.
The transition between two phases - an infinitely thin separation plane
the unique compositional phase between two phases
What are some surface properties?
Measure of the texture of a surface
How is surface roughness quantified?
by the vertical deviations of a real surface from its ideal form:
large deviations - rough surface;
small deviations - smooth surface.
(can lead to wearing)
the ability of a liquid to maintain contact with a solid surface, resulting from intermolecular interaction
extent to which a liquid will spread over a solid surface and is measured by a contact
angle made by the intersection of the liquid/solid interface and the liquid/air interface.
List the different wetting with contact angles
x=0 - Spreading
x < 90 - Good wetting
x = 90 Incomplete wetting
x > 90 Incomplete wetting
x > 180 No Wetting (literal ball)
Contact angle phenomenon
a balance between the force with which the molecules of the drop liquid are attracted to each other (a cohesive force) and the attraction of the liquid molecules for the surface (adhesive force).
nominal strain that occurs when the temperature of a material is changed
The ability of an object to transfer heat or electricity to another object
