The process of shot peening metal or other industrial parts requires the right knowledge and experience to produce the desired effect of increasing fatigue strength, preventing cracking or creating a uniform surface.
The incorrect approach to shot peening could be very costly by damaging a piece of metal or a part. That’s why it is critical to understand the shot peening process parameters and how to determine the best approach for each shot peening treatment.
What Are the Shot Peening Process Parameters?
Before starting a shot peening treatment, several critical parameters must be considered:
- Air pressure
- Mass flow
- Impact angle
- Shot speed
- Exposure time
- Nozzle size
- Distance between the nozzle and the metal/part
Each of these parameters must be weighed in relation to each other, not viewed in silos. Otherwise, you risk damaging the metal or part by using the wrong type of nozzle, shooting the subject too close, or exposing the subject to the treatment for too long.
How Do You Determine the Best Approach for Each Treatment?
Mathematical formulas allow you to correctly calculate the best shot peening treatment. Specifically, geometrical models and dimensional analysis provide the answer.
Fortunately, advances in computer technology have made it easier to determine the correct shot peening treatment for each material.
Technology allows you to build a diagram of the metal or part, input the shot peening process parameters, and calculate the maximal normal impact speed (m/s) to treat the subject material.
Once you make this determination, you can accurately and correctly treat the subject material to achieve the desired result of increasing strength, reducing the risk of cracking or corrosion, and creating a uniform finish.
