Mechanical Behavior of Iron-bonded Grinding Wheel after ELID (Electrolytic In-process Dressing) Electrolysis Procedure by Nanoindentation

摘要

We have evaluated the effect of oxide films on polishing behavior during ELID grinding process. The evaluation procedure used nano-indenter to analysis quantitatively the oxide film's mechanical properties on iron-bonded grinding wheel after ELID electrolysis. As a result, the oxide film's mechanical properties increased with the indent depth increasing. The plots of indent load and displacement for oxide films showed slight variations with time. The content of iron group elements in grinding wheel also has higher impact on oxide film' s properties.
