Surface energy of ceramic materials. Ceramics play an important role in engine efficiency and pollution abatement in automobiles and trucks. The surface free energy is equal in respect of figures to the work required to form a new unit surface. Surface energy of ceramic materials dcic report unknown binding january 1 1969 by jules j duga author see all formats and editions hide other formats and editions. The lower the solid s surface energy relative to the liquid s surface tension the weaker the attractive forces are and this will repel the coating.

Surface energy values usually have the units of mj m 2. Price new from used from paperback please retry 814 57. Some sources quote the critical surface tension in units of mn m which is equivalent to surface energy. For an energy characterization 30 samples of gc and 30 samples of pvs were built.

Determination of free surface energy values for ceramic materials and polyurethane surface modifying aqueous emulsions 1. For example one type of ceramic cordierite a magnesium aluminosilicate is used as a substrate and support for catalysts in catalytic converters.

The strength of attraction between a material and a coating is determined by the relative surface energy surface tension of the materials. Some sources quote the critical surface tension in units of mn m which is equivalent to surface energy.

It was chosen for this purpose because along with many ceramics it is lightweight can. The intrinsic surface energy of an inorganic ceramic surface such as metal oxide is considered to be higher as compared with organic material sur face. Under the ordinary circum stances surface organic contamination may change the wettabil ity. In an ambient air atmosphere oh groups and molecular water are adsorbed on the surface.

The objective of the present study was to evaluate the effect of surface modifications with hydrofluoric acid gel concentration 10 on the surface energy of 2 dental feldspathic ceramics gc and pvs.
