Level : Advanced

Course Content


      • Rupture phenomena:
      • Ruptures study: material characteristics, influences of metallurgy and surface treatment, design parameters, consequences due to the modification of material behavior.
      • Characteristics of the main kind of ruptures: tensile and compressive stress with necking appearance, influence of the resilience and the transition temperature with regards to the service temperature, mechanical fatigue.
      • Rupture face analysis: mechanisms of rupture, surface morphology.
      • Solutions to avoid rupture: design parameters, limiting stresses, operating conditions and limitations.
      • Wear phenomena:
      • Wear study: friction principle with friction factor and wear rate, tribology.
      • Characteristics of the main kind of wear: adhesive wear depending on the lubrication mode, abrasive wear through particle presence, erosive wear due to flow, mechanical surface fatigue on gears and bearings.
      • Morphology of a worn surface: temperature colors, scratching, scoring, seizure.
      • Solutions to avoid wear: design parameters, limiting friction, operating conditions.
      • Case studies: rupture and wear examinations of machinery parts (bearings, mechanical seals, rotors), analysis of some failures on process centrifugal pumps, reciprocating and centrifugal compressors and gearbox.

      • Repair philosophy: integrating all the criteria to choose the best solution: repair or replacement.
      • Different modes of repair: welding, surface treatment, metal striching, deposits (HVOF application).
      • Costs: repair costs, delivery time, on site capabilities.
      • Case studies: description of different approaches used to repair some machines and components.

Learning Objectives

  • Upon completion of the course, participants will be able to:
  • prevent mechanical failures and reduce operating costs,
  • apply a methodology to identify the type and the failure root cause,
  • propose improvements on machinery reliability.

Ways & Means

  • Case studies based on industrial and actual feedback.
  • Interactive course.
