AB  - Composition and production procedures of the mullite-based coatings for the protection of metal surfaces in the conditions of cavitation, wear and corrosion were investigated. An ultrasonic vibration method according to the ASTM G32 standard was used to characterize the coating. The change in the mass of samples as a function of the cavitation time was monitored and the cavitation rate was determined. The occurrence and development of the coating surface damage were monitored using a scanning electron microscope. Based on the value of cavitation rate and analysis of the surface damage morphology, the cavitation resistance of coating was determined. Coatings have shown the satisfactory resistance in the conditions of cavitation and possibility of application for the protection of parts of equipment in metallurgy and mining.

AB  - The effect of proof over-pressure on pressure vessels structural integrity is analysed. Risk based approach is applied using Failure Analysis Diagramme to assess likelihood of failure. Special attention is paid to crack-like defects detected by NDT regular testing which are unacceptable by standards, but difficult to be repaired. It was show, using two examples, that such defects can remain if some strict conditions are fulfilled. In any case, with or without crack-like defects, it was shown that testing of pressure vessels with significant over-pressure can cause much more problems than it has benefits, because it acts more like the first step in eventual failure, than being proof to anything.

AB  - Risk based analysis of reverse hydro power plant penstock structural integrity is performed using fracture mechanics parameters. To assess its structural integrity, extensive testing of the full-scale prototype had been performed, including hydrostatic over-pressurizing, during the design phase. More recently, the Failure Assessment Diagram has been used to evaluate probability, whereas phenomenological analysis has been used to estimate consequence, in the scope of common risk estimation. It is shown that over-pressuring has potential detrimental effect on pipeline safety, i.e. structural integrity.
