摘 要: The use of NDE techniques such as Barkhausen Noise Analysis (BNA) for detection of grinding induced thermal damage is often application specific due to variables in the grinding process. In this paper, Malkin's grinding energy partition model is applied in conjunction with BNA to reliably predict occurrence of thermal damage in through-hardened bearing steels independent of grinding variables. Various intensities of material transformation such as surface, sub-surface retempering and rehardening were accurately detected and validated by metallography and residual stress analysis. The results demonstrate that material-specific models independent of grinding process variables can be effectively utilized to predict thermal damage.

由于磨削工艺中的变量存在差异,采用巴克豪森噪声分析(BNA)等无损检测技术来检测磨削引起的热损伤往往具有应用特定性。本文将马尔金的磨削能量分配模型与BNA结合使用,以独立于磨削参数的方式可靠预测通过淬硬轴承钢的热损伤发生情况。通过金相学和残余应力分析,准确检测并验证了不同强度的材料转变,如表面、次表面回火及再硬化。结果表明,可针对特定材料开发出不依赖于磨削工艺变量的模型,从而有效预测热损伤。(C)2017 Elsevier Ltd 代表 CIRPP 出版。
