    Erosion problem in tool steel using cold box core-making process por Rodríguez, Eduardo, Pérez, Alberto, Mercado Solis, Rafael David, Velasco Tellez, Abraham, Jiménez, Omar, Flores, Martín, González, Marco Aurelio, Ibarra, Jesús

    Publicado 2019
    “…Erosion tests were carried out at impingement angles from 20° to 90° and air drag pressures of 1.38, 2.07 and 2.76 bar (20, 30 and 40 psi). The main results are summarized as follows: (i) The harder material, the lower erosion; (ii) the maximum erosion rate is at 30°; (iii) Little difference in erosion rate at impact angle of 60° and 90° for a constant pressure tested regardless of the hardness level; (iv) As the pressure increases, so does the erosion rate, being more sensitive for low impact angles. …”
