The bristle tips are designed to strike the corroded surface with kinetic energy that is equivalent to standard processes that use grit blast media. Immediately after the bristle tips strike the surface, they retract (“rebound”) from the surface, which results in both corrosion removal and micro-indentation that exposes fresh surface.
Consequently, surfaces that have been treated by Bristle Blasting have a texture and visual cleanliness that mimics those obtained by traditional grit blasting processes.
Corrosion, Mill Scale and Coating Removal Improved Integritiy of Treated Surface
Negligible Heat Generation
Simple / Economical
Restores surface to near white metal visual standard (or Sa 2½, NACE No. 2 or SSPC-SP 10)
Generates compressive residual stress along the treated surface for crack growth resistance, improved fatigue life and improved corrosion resistance
Surface free of thermal damage/heat marking
Eliminates the need for complex and costly abrasive blast equipment
Surface Texture / Anchor Profile
Roughness capability from 40-120 μm Rz (1.6-4.7 mils) – depending on treated material. Also on weld seams
