Blasting and Shot Peening

Overview

DiFruscia Industries utilizes its blasting options to meet pretreatment and texture requirement for various finishes. The process works on a number of surfaces and it is a fast and efficient method to prepare old materials for re-usual.

Shot peening is the process of bombarding the surface of a metal component with small spherical media called shot. During the shot peening process, each piece of shot that strikes the component acts as a tiny peening hammer, creating a small indentation or dimple on the surface. To create the dimple, the surface of the material must yield in tension. Below the surface, the material tries to restore its original shape, thereby producing below the dimple, a hemisphere of cold-worked material highly stressed in compression.

Key Performance Properties of Blasting & Shot Peening:

• Increases the life of the part
• Creates a uniform layer of compressive stress at metal surfaces
• Increases resistance to fatigue failures, corrosion fatigue,
  stress corrosion cracking
• Removes old coatings
• Cleans off dirty surfaces or equipment
• Fast and efficient process
