Restoration of worn parts

Restoration of worn parts bases on part dimension increasing after DC maschining by obtaining surface porosity in form of deep narrow grooves. Surface porosity may be removed by different methods or can serve as pockets for holding liquid lubrication

Fig. 1 - Variants dimension increasing with removing surface porosity by:
1 - Flattenig of fin tops
2 - Electrospark alloying
3 - Gap filling by Polymeric Repair Composite
4 - Gap filling by wire





Variants of dimension increasing 
 with removing surface porosity
Fig. 2 - Variants of shaft repair:
1 - worn site,
2 - after DC machining,
3 - after DC machining and cut-off of sharp fin tops,
4 - after DC machining with fin top flattening,
5 - repare paste inside fins and above,
6 - repare paste only inside fins

Main advantages

  • Using of traditional turning machines
  • No thermal action
  • Possibility of renovation with surface hardening
  • Possibility to put solid or liquid lubricants in grooves of friction surface
