【摘要】：在商用4Cr5MoSiV模具鋼中添加了0.8wt%石墨烯,制備了鎂合金鑄造模具用石墨烯改性的新型材料,并進行了顯微組織、物相組成、耐磨損性和熱疲勞性能的測試。結果表明,添加0.8wt%石墨烯顯著提高了材料的耐磨損性和熱疲勞性。與商用材料4Cr5MoSiV相比,該新型材料的25、300、600℃磨損體積分別減小84.4%、85.8%和91.2%,熱裂紋級別從12級變?yōu)?級。
[Abstract]:A new material modified by graphene for magnesium alloy casting die was prepared by adding 0.8 wt% graphene into commercial 4Cr5MoSiV die steel. The microstructure, phase composition, wear resistance and thermal fatigue property were tested. The results showed that the wear resistance and thermal fatigue property of the materials were significantly improved by adding 0.8 wt% graphene. Compared with commercial material 4Cr5MoSiV, the wear volume of the new material at 25300600 鈩，
