AB  - Abstract

Film forming amines (FFA) are corrosion inhibitors added to power plant
water. The major concern associated with their application is the thermal
stability in the high temperature power plant water medium, along with the
risk of decomposition into low molecular weight organic acids that can cause
corrosive damages in the water/steam cycle. However, there is still a lack of
sufficient data on the thermal stability of FFA corrosion inhibitors. This paper
presents a comprehensive critical review and state‐of‐the‐art assessment of the
results obtained from studying the thermolysis of FFA corrosion inhibitors in
power plant water/steam cycle conditions, highlighting the relevance for
practical application and research needs. Temperature, exposure time, initial
concentration, and alkalizing agents were identified as key factors influencing
the thermal stability of FFA in high temperature power plant water. Organic
acids are found in concentrations harmless to metal tubes. Advanced scientific
background information and additional research are required on this topic.

AB  - Film forming amines (FFA) are organic additives used to prevent corrosion in power plant water/steam cycle. FFA create a non-wettable film on the inner tube wall that represents a physical barrier between the tube wall and moisture containing corrosive contaminants. Octadecylamine (ODA) is the most widely used FFA in power industry. Despite the fact that the thermal stability determines the utilization of ODA in the high temperature water/steam cycle conditions, there is a scarce of relevant scientific data. In this paper the published results of the influence of residence time on the ODA decomposition rate in water/steam cycle were critically reviewed. For studying ODA thermolysis, steel autoclaves and high-temperature test rig were used. ODA was observed to be a harmless compound for the application in power plants.

AB  - The friction coefficient in many friction stir welding researches is generally used as an effective, constant value without concern on the adaptable and changeable nature of the friction during welding sequence. This is understandable because the main problem in analyzing friction in friction stir welding are complex nature of the friction processes, case-dependent and time dependent contact between the bodies, influence of the temperature, sliding velocity, etc. This paper is presenting a complex experimental-numerical-analytical model for estimating the effective friction coefficient on contact of the bobbin tool and welding plates during welding, considering the temperature at the contact as the most influencing parameter on friction. The estimation criterion is the correspondence of the experimental temperature and temperature from the numerical model. The estimation procedure is iterative and parametric - the heat transport parameters and friction coefficient are adapted during the estimation procedure in a realistic manner to achieve relative difference between experimental and model's temperature lower than 3%. The results show that friction coefficient varies from 0.01 to 0.21 for steel-aluminium alloy contact and temperature range from 406 degrees C to 22 degrees C.
