[vc_row][vc_column][vc_acf field_group=”3279″ field_from_3279=”field_5b7cf545d605d” show_label=”yes” el_class=” “][vc_acf field_group=”3279″ field_from_3279=”field_5b7cf51dd605c” show_label=”yes”][vc_acf field_group=”3279″ field_from_3279=”field_5b7cf568d605e” show_label=”yes”][/vc_column][/vc_row][vc_row][vc_column][vc_column_text] Abstract To meet an increased energy demand, it is necessary to increase steam turbine operating temperature of coal-fired power plant from conventional practice of 540°C to ultra/advanced ultra-supercritical practice over 700°C. Because of this temperature increase, traditional ferritic/martensitic and austenitic steels cannot survive. […]

The study of water-line corrosion in static and dynamically flowing electrolytes using multi-electrode sensor in combination with electrical resistance method

[vc_row][vc_column][vc_acf field_group=”3279″ field_from_3279=”field_5b7cf545d605d” show_label=”yes” el_class=” “][vc_acf field_group=”3279″ field_from_3279=”field_5b7cf51dd605c” show_label=”yes”][vc_acf field_group=”3279″ field_from_3279=”field_5b7cf568d605e” show_label=”yes”][/vc_column][/vc_row][vc_row][vc_column][vc_column_text] Abstract In this work, a new sensor system was developed based on an integrated multi-electrode technique in conjunction with an electrical resistance (ER) method. This new method has allowed galvanic currents flowing among the multi-electrodes and the total metal loss simultaneously measured. On […]

Long-term corrosion of steel chains on pacific ocean beach sand

Very few data are available, particularly for […]

Long-term corrosion investigation of mortar embedded wall-ties exposed to atmospheric corrosion

Corrosion of such wall-ties when embedded in the mortar can be severe and consequently lead to a premature structural failure of the wall. Available atmospheric corrosion models can be used […]

In-situ Corrosion Protection Performance Assessment of Petrolatum-Based Pile Wrapping Systems at the Tasman Bridge

The bored piles consist of mild steel tubes (casings) filled with reinforced concrete. Divers have determined that local corrosion of the steel casings has occurred to expose […]

Characterization of surface Topography for Corroded Steel Members Exposed to Marine Environments

Therefore, many of these infrastructures are in a condition requiring repair or replacement. Corrosion affects the performance […]

Inhibition at a polyurethane-based coating defect with lanthanum 4-hydroxy cinnamate and candidate MIC inhibitors

Unfortunately, it does have some limitations, such as vulnerability towards corrosion and, depending on the service conditions, microbiologically influenced corrosion (MIC). A simple strategy for protecting steel […]
