1. Study on influence of the PTA-P welding process parameters on corrosion behavior of Inconel 625 coatings
ABSTRACT In the present work, PTA welding process was used to investigate the influence of welding parameters on the dilution, microhardness and corrosion resistance of Inconel 625 alloy coatings on the API 5L X70 grade steel. The electrochemical impedance spectroscopy (EIS) and linear potentiodynamic polarization (LPP) measurements were used to study the pr

2. Analysis of the corrosion scales formed on API 5L X70 and X80 steel pipe in the presence of CO2
Longitudinal welded joints samples of X70 and X80 API grade steel pipes were exposed to a deaerated 1% NaCl solution containing CO2, at temperatures in the range of 25 ºC to 80 ºC for 48 hours. Analogous samples were exposed to the adjacent vapour phase. The layer of corrosion products which formed on the base metal and welded regions of the samples was in

3. Estudo das transformaÃÃes de fase em Pseudo â ZTAs para aÃo API 5L X-70 visando desenvolvimento de dispositivo substrato
The microstructure transformation of structural steel has been studied from continuous cooling in metallic means to simulate the microestrutural transformations in different places in a HAZ (Heat Affected Zone). The studied material is Steel API 5L X70, largely used in piping in the Petrochemical Industries for its hight mechanical resistance and low weight,
