Introduction to ultrasonic stress relief
This section describes a variety of processes and effects related to ultrasonic stress relief for materials processing, replacing conventional heat-treatment processes which can be energy-intensive and / or impractical for large components. Some of the beneficial effects include:
- Fast stress relief
- Fatigue life extension
- Accelerated aging and material-properties stabilization
- Early detection of mechanical defects
- Ability to treat components too large for any oven
- Algae, Barnacles & Biofilm removal
- Surface implantation of different particles and powders
- Quenching and hardening
- Improved surface coating
- Coatings over welds to extend fatigue life
- Accelerated neutralization of free radicals
- Polymerization
- De-polymerization Degassing and de-bubbling. Improved alloying and casting
- Production of homogenous biocompatible alloys. Facilitated implantation and/or penetration
- Enhanced cleaning and sterilization
- Deep capillary cleaning
One or more of a variety of treatment methods may be used depending on the required effects and equipment limitations, eg. size and access. The methods used include:
- MMM ultrasonic (screw-on / clamp-on)
- Ultrasonic bath
- Ultrasonic vapor chamber
- Ultrasonic sand blasting
- Ultrasonic chemical etching,
- Shot and ball peening
Many applications will be described in detail in the following pages, including:
- Ultrasonic stress relief
- Fatigue life testing
- Preventive maintenance
- Real-time cleaning of deposits and scaling
- Cleaning, descaling, cutting, liquid-metals agitation
- Ultrasonic vibrothermography
- Ultrasonic dry cleaning
- Optimized surface coating
