Abstract
The study objective is to improve the performance of titanium alloy parts used in aircraft jet engines with electrospark alloying. The technology can be used for hardening compressor rotary vanes and rod ball joints, protecting compressor blade leading edges from erosion. We studied the alloyed layer formation process and determined the layer structure and composition. The study presents experimental findings of the Ti alloy electrospark alloying as certain substances were introduced into the interelectrode gap. We also assessed the relationship between the electrospark alloying process variables and the alloyed layer surface finish.
