The temperature changes of special points on the coating rod were measured using a thermocouple.
Chapter one summarizes the corrosion problem of steel in concrete and points to the coating of reinforcing steel as a way of mitigating this huge worldwide problem.
Then the rate decreased to a low level once the friction system became quasi-steady and the temperature became approximately stable near the melting point of the coating rod.
The present paper discusses a model equation for the flow in distribution chambers, which can be used to predict effectively both the geometry of the distribution chamber which guarantees constant film thickness for a fixed operating point of the coating facility, and the film thickness deviations for given chamber geometries and operating points.
From the engineering point of view, the coating applied at the cold mode using a powder containing 10 wt.% MoS2 is the most promising.
The correlation between the porosity values of the coatings and the level of C and OH traces observed by ToF-SIMS points to a marked effect of the coating contaminants on the sealing performance of the coatings and on the corrosion resistance of the coated systems.
Film morphology investigations have shown that the coatings are homogeneous, and the substrate-coating zone points to the high adhesion of the coating to the substrate.
The understanding of the process through use of this test method leads to the ability to identify the critical control points of film coating.
The fractographic analysis of the fracture surface of the coated specimens points out the characteristic heterogeneous nature of the coating, particularly regarding some of its mechanical properties, such as fracture toughness.
The results indicate that the damage increases with increasing stress and obeys the power-law characteristics with the power exponent of 0.5, and the damage is 1 as the stress reaches the critical point corresponding to the failure of the coating systems.
