| description | The paper presents the results of the investigation devoted to the
influence of wire electrical discharge machining modes on crack
formation and surface layer morphology of the titanium alloy. The
aim of the paper is to obtain interrelation data about processing
modes with depth of microcracks penetration, as well as on the
influence of processing modes on the morphology of the surface
layer, in particular, on the group of parameters Rk. It is shown by
using scanning electron microscopy that the depth of microcracks
depends of the number of passes and processing conditions. The
maximum depth is 12 μm after the first pass, the minimum is 0,9
μm after the fourth pass. The groups of parameters Rk study by
the method of profilometry made it possible to conclude that the
most favorable oil-retaining microrelief is formed after the third
pass. |
