This research paper has as main objective to test the effect of thermal cycling on 2904 Oscar Fabián Higuera Cobos et al. the abrasive wear behaviour of the MOLDMAX HH alloy (UNS C17200). The material was subjected to variations in solubilisation temperature of 750 °C, 800 °C and 850 °C for 1 h and aging times at 300 °C of 1 h, 2 h and 3 h. Microstructural and chemical characterization was performed using Scanning Electron Microscopy (SEM-EDS) and Dispersive Energy X-ray Fluorescence (EDXRF), respectively. Abrasive wear behaviour was evaluated under the guidelines of ASTM G65. The results show a significant improvement in the abrasive wear behaviour of the alloy compared to the material in supply condition (T6). The lowest volumetric loss values were obtained from the samples that were subjected to thermal treatment of solubilisation at 850 °C and water cooling with a volumetric loss of 169 mm 3 , in comparison to the supply material with a volumetric loss of 347mm 3 .
