Description
The author studied the effect of high current pulsed electron beam (HCPEB) treatment on fretting wear ability of D2 die steel. It is shown that the most pronounced structural changes occur in the near-surface region, where the energy deposition is at its maximum. The fretting tests under dry condition were carried out on both treated and untreated specimens. The HCPEB treatment increases the fretting wear resistance significantly, and the improvement is further enhanced by surface pre-alloying by TiN and Cr. SEM analysis of the wear scars showed that the fretting wear mechanism of Cr coating is adhesive and oxidation wear, that of the TiN coating and non-coating D2 die steel is particle detachment through the propagation and fracture of fatigue microcracks on surface, and slight adhesive and oxidation wear is found, its wear mechanism is more complex
