Research on the Wear Behaviors of WC-8Co and Al2O3-TiC Conical Dies
Source abstract
Abstract
采用冷、热压烧结技术分别制备了WC-8Co和Al 2 O 3 -TiC两种拉拔模具. 研究了该两种不同拉拔模具用于实际拉拔加工45#钢线时的摩擦磨损行为, 并对其磨损机理进行了分析. 结果表明: 两种拉拔模具均具有较好的强度和硬度, 能较好地进行拉拔加工, 其内孔磨损在工作区及定径区最为严重, 磨损面有金属脱落元素、模具颗粒脱落元素及润滑脂残留物. WC-8Co和Al 2 O 3 -TiC两种拉拔模具的磨损机理不尽相同, WC-8Co模具主要为粘着磨损和磨粒磨损, 而Al 2 O 3 -TiC模具则以磨粒磨损和表面疲劳磨损为主. Al 2 O 3 -TiC拉拔模具更适合于45#钢线材的拉拨.
