摘要

    摘要
  • 摘要: 使用的Al2O3对磨材料测试GC2025高硬合金的摩擦性能，并以TC4与9CrSi进行对比，通过实验测试的手段分析载荷对非自耗真空熔炼GC2025高硬刀具的滑动磨损行为的影响。研究结果表明：当载荷由2.5 N提高到20 N的过程中，GC2025高硬合金摩擦系数减小。提高载荷后，GC2025高硬合金以及对比合金均发生了磨损量的线性增大。相比较TC4合金与9CrSi合金，GC2025高硬合金更适合于大载荷环境。以较小的2.5 N载荷进行处理时，在磨痕上形成了平行于滑动方向的犁沟。逐渐增大载荷后，在试样表面形成了更多的附着物，并对犁沟造成更大范围的被覆。提高载荷后，磨屑内形成了5μm尺寸的不规则剥落物。处于2.5-10 N的载荷区间中，GC2025高硬合金磨痕深度线性增长；当载荷继续从10 N提高到20 N时，表面形成的磨痕深度保持基本恒定的状态。相对于TC4，GC2025高硬合金达到了更小的磨损率。
    Abstract: Al2O3 was used to test the frictional properties of GC2025 high hardness alloy, and TC4 and 9 CrSi were compared to analyze the effect of load on the sliding wear behavior of GC2025 high hardness tools in non-consumable vacuum smelting.The results show that when the load increases from 2.5 N to 20 N,the friction coefficient of GC2025 high hardness alloy decreases.After increasing the load, the GC2025 high hardness alloy and the contrast alloy show a linear increase in wear.Compared with TC4 alloy and 9 CrSi alloy, GC2025 high hardness alloy is more suitable for a large load environment.When treated with a small 2.5 N load, furrows parallel to the sliding direction are formed on the wear marks.After increasing the load gradually, more attachments are formed on the surface of the sample and the furrows are covered over a larger area.After increasing the load, irregular exfoliations with a size of 5 μm are formed in wear debris.In the load range of 2.5-10 N,the wear mark depth of GC2025 high hardness alloy increases linearly.When the load continues to increase from 10 N to 20 N,the depth of wear marks formed on the surface remains basically constant.Compared with TC4,The GC2025 high hardness alloy has a lower wear rate.
