We introduce a healing efficiency factor and conclude that the coating modulus, thickness and roughness are responsible for the mechanical improvement of fibers.
Parameters of deposited coatings such as nano-hardness, Young's modulus, adhesion, friction coefficient and roughness were measured.
Using a constant base with modulated crosslink density we were able to vary the material modulus while keeping surface chemistry and roughness constant.
The purpose of this in vitro study was to evaluate the flexural properties (strength and modulus), failure mode, superficial morphology, and roughness of two CAD-CAM glass fiber posts (milled at different angulations) compared with a commercially available prefabricated glass fiber post.
Once immersed in DI water, the film became softer, where roughness, modulus and hardness were reduced by about 100%.
Some factors have great effect on lubrication, such as clearance, oil viscosity, oil supplying hole, bearing elastic modulus, surface roughness, oil supplying pressure and engine speed and bearing width.
It was found that irrespective of whether the dopant was biologically derived, the physical properties tended to group together with films having either a low roughness, low modulus and high strain, or vice versa.
It was observed that the hardness, elastic modulus, surface roughness, friction coefficient and wear resistance values of coated samples were higher than the uncoated CP-Ti values.
The influences of the nano-film's adhesion length, thickness, elastic modulus, roughness and peeling angle on the peeling force were considered as well as the effect of the viscoelastic behavior.
