The effects of surface coating on the plastic deformation of metallic specimens have been studied extensively in the past. With a few exceptions, the investigations were focused on f.c.c. metals at room temperature and revealed a hardening effect [ ]. The surface film softening, a recently discovered phenomenon % takes place in b.c.c. metals at low temperatures where the temperature dependence of yield stress is large. Therefore, it is essential to know the low-temperature deformation mechanism of b.c.c. metals in order to understand the SFS phenomenon. 

Thermal Expansion Coefficients. The thermal expansion of a lossy film should be observed as a steady decrease in frequency. The coated devices we studied exhibited a steady frequency shift with temperature. If this change In frequency Is the result of film expansion,then the slope of this frequency curve should be proportional to the thermal expansion coefficient. The T of polymeric materials can be Identified by the change In the thermal expansion coefficient at the T. To verify the effect of surface coating coverage on observed SAW frequency-temperature response behavior, the results for the airbrush-applied films studied here must be compared with results obtained from contiguous films of known thickness.

The surface friction is represented by the coefficient of friction, which, in turn, represents the cumulative effects of surface coating, surface fini.sh and surface roughness, surface hardness of both tooling and workpiece, as well as lubricant at the interface [38, 57].

The main value of salt-spray tests is in the evaluation of the effectiveness of phosphate coatings in restricting the spread of rust from scratches or other points of damage in a paint film. This feature is of particular interest to the motorcar industry, as vehicles are often exposed to marine atmospheres and to moisture and salt when the latter is used to disperse ice and frost from road surfaces. Great care is needed in the interpretation of a salt-spray test, as it has been found to favour thin iron phosphate coatings more than is justified by experience with natural weathering. In the motorcar industry the present custom is to use zinc phosphate coatings on the car bodies and all other parts exposed to the outside atmosphere. 

As a result, scale layer was always formed on the smooth surface of reactor wall as well as irregular. Microstructure was blanketed as soon as the surface was coated with a Ti02 scale film. It could be deduced that once scales were formed, the effect of surface geometrical shape would be more important than its microstructure. 

From the foregoing, it seems likely that apart from a small number of specialist medical applications, the efficacy of surface coated devices may be compromised by antibiotic-resistant bacteria, together with the barrier effect provided by conditioning films that will rapidly coat biomaterials in situ.43...
