Factors that have an Effect on Surface Profile

Abrasive durability/surface hardness, abrasive shape, abrasive size, impact energy, impact angle, and embedment.

Abrasive Durability/Surface Hardness

Bicarb media vs Alox, Mild Steel vs Hardened Steel

abrasive durability surface hardness
Variable Effect
More durable abrasive Deeper profile
Less durable abrasive Shallower profile
Hardened steel Shallower profile
Mild steel Deeper profile

Abrasive Shape

Steel Shot vs Steel Grit

steel shot vs steel grit
Variable Effect
Round Abrasive Dimpled, peened profile
Angular abrasive Sharper, rugged profile

Abrasive Size

#20/40 Garnet vs 80# Garnet

steel shot vs steel grit
Variable Effect
Larger abrasive Deeper profile
Smaller abrasive Shallower profile

Impact Energy

Nozzle pressure (abrasive velocity), nozzle wear, nozzle standoff distances, dwell time

abrasive blasting impact energy
Variable Effect
Low angle More scuffed profile
High angle More peak 'n' valley even profile

Impact Angle

Straight on blasting vs side reach blasting

blasting impact angle
Variable Effect
Larger abrasive Deeper profile
Smaller abrasive Shallower profile

Embedment

Slag vs Garnet

slag vs garnet embedment
Variable Effect
Large friable irregular grains Higher risk of embedment
Smaller durable regular grains Lower risk of embedment
