| dc.description | The effect of corrosion by H2SO4 on the values of room temperature thermal diffusivity (α) and the microstructure of API5L-X52 pipeline steel are studied. The samples were exposed for 3, 6, 9, 12 and 15 days in a corrosive solution in an atmosphere with relative humidity of 57.16% in average and at temperature of 23.6 °C. The α values were measured by the photoacoustic technique in a heat transmission configuration. Our results show a decrease with the corrosion time (t), with a behavior described by an exponentially decreasing curve. Microestructural study on the samples revealed the appearance of irregular surfaces with corroded grain frontiers, porosity and fractures of micrometer size as a consequence of corrosion, as well as a presence of phases mainly composed by tetra hydrated iron and manganese sulphates. The decreasing evolution of α vs t show the activity-passivity behavior in the corrosion process. | - |
