“…Due to the results found in the studies made by electrochemical polarisation experiments in chloride containing solution elsewhere, a similar corrosion damage behaviour is expected when the material is exposed in a long-term outdoor exposure test which involves an aggressive chloride containing electrolyte [4,5,7]. In contrast to electrochemical polarisation, the advantage of an outdoor exposure test is an information about the corrosion behaviour in natural climatic conditions [8][9][10][11][12][13]. With regard to the comparability of the damage evolution, it is assumed that the same corrosion mechanism is initiated when the used electrolyte is similar in both experiments.…”

The corrosion behaviour of a spark plasma sintered CrMnNi high-alloyed steel, without and with 10 vol.% zirconia particle reinforcement was investigated by potentiodynamic polarisation in 5 wt.% sodium chloride solution and by an one year outdoor exposure test. After the polarisation test both materials revealed a similar damage behaviour as in the outdoor exposure test. The unreinforced material was attacked by pitting corrosion, whereas the particle reinforced material showed a more homogeneous corrosion attack involving an intensified particle detachment. Furthermore, investigations of the unreinforced steel by white light interferometry revealed pit depths of approximately 65 μm after potentiodynamic polarisation and 36 μm after one year outdoor exposure. In contrast, for the composite a damage evolution due to particle detachment was found in both experiments.

The main objective of this paper is aim to take fatigue reliability updating evaluation of hydraulic steel gate based on the Bayes theorem. The fatigue cracks can be detected for existing structures, and fatigue reliability assessment can be updated by the nondestructive inspection. In this paper, based on the probabilistic characteristics for NDI techniques and the Bayes theorem, a fatigue reliability updating assessment model for existing steel gate components is proposed. The results showed that the fatigue reliability will increase with no cracks detected, decrease with unknown cracks detected, and change remarkably with cracks detected.

The properties of polyurethane containing five kinds of model phenolic additives were investigated. The IR spectra of polyurethane containing phenolic additives indicated that the phenolic additives reacted with isocyanate groups in a polyisocyanate compound. For an index of anticorrosion, the tensile adhesion strength was measured for polyurethane coatings with phenolic additives on steel plates treated with the salt-water spraying test for 3000 h. It was found that there was a relationship between the tensile adhesion strength of polyurethane and the density. We considered the reason to be that the increase in density (i.e., a reduction in free volume) should provide a route to reduce salt-water access to an adhesive bond. The increase in density was explained by the term antiplasticizers, which means that the phenolic additives reduce the free volume that is available for molecular motion in the stiff chain of polyurethane. In the polyurethanes with every phenolic additive, the elongation was increased, the moduli were decreased, the storage modulus was decreased, and the coefficient of thermal expansion was increased. These phenomena are the characteristics of plasticizers. Thus, the phenolic additives have both the character of antiplasticizers and plasticizers, but the polyurethane with phenolic additives had more characteristics of plasticizers than those of antiplasticizers.
