The Application of Fractal Theory in EDM Surface Strengthening TC4 Titanium Alloy

Abstract:

EDM Surface Strengthening TC4 titanium alloy is a kind of very effective surface strengthen method, and its development prospect is very considerable. The medium in the discharge process has characteristic of self-similarity, which can be well described by fractals. And the discharge channels are an important factor affecting the distribution of discharge energy. The discharge process in kerosene and mixed powder dry medium have been simulated by using fractal theory. And the actual strengthening experiment was conducted in two different medium. The results prove that trajectory characteristics based on fractal theory are basically in agreement with the experiment result of EDM Surface Strengthening TC4 titanium alloy. The fractal theory can guide the EDM surface strengthening research of TC4 titanium alloy.
