Roto Peening: What is it? Similar to shot peening, roto peening inhibits corrosion and prevents metal fatigue failures in important components by forming a compressive surface stress layer. Since corrosion removal can also remove the initial compressive layer, it is frequently used in aviation after corrosion removal. This protective coating is restored using Roto Peening, which can occasionally reach hard-to-reach places without disassembling components. No matter where your aircraft is located, JAX Aero has the required equipment and expertise to perform roto peening. Our transportable capabilities, along with our structural repair and fuel leak repair services, assist minimize downtime and save costs.
