Definition - What does Grit Inclusions mean?
Grit inclusions are the result of fine particles of heavy mineral matter adhering to a metal's surface, which causes the effects of corrosion on the surface to be accelerated.
Corrosionpedia explains Grit Inclusions
Grit inclusions are typically a undesirable byproduct of abrasive blasting, which is a process where abrasive particles are accelerated and forcefully directed against a surface. The particles are intended to remove contaminants from the material's surface and condition the surface for subsequent finishing. However, residual grit particles may become embedded on the metal's surface.
Adequate knowledge about grit inclusions can help prevent corrosion or wear on tools made of steel. For instance, altering the environmental chemistry that surrounds a metal being blasted along with the examining the interfacial kinetic effects is suggested.
