Hardening of the Grey Cast Iron through the Vibrating Electrode Method Using a WC Electrode and in Combination with TiC and Ti Electrode

Résumé

There have been tested samples of grey cast iron, the hardening being made through WC coating through the vibrating electrode method with a layer, two layers and through double layers combined with Ti and TiC. Besides double layers combined there were also made triple combined layers. Afterwards there were taken photographs of macro-hardness and HV50 micro-hardness into the material in into the layer. There were also made rugosity measurements. Then in order to appreciate the internal stresses were made ring specimens type Naimov. On the exterior of these specimens were made coatings with the vibrating electrode.
