..., the surface profile was non-angular and the angularity requirement in the project coating specifications had not been clearly defined (which will be discussed late in this paper). This brings a question: Have the typical surface profile height and abrasive blast cleaning requirements in today’s pipeline...

...Abrasive blasting is an excellent cleaning process prior to painting, but the blast profile needs to be defined, especially if it can exceed the film thickness of the paint to be applied. In this case the blast profile was in the 0.4 to 1.2 mil range and the thickness of the primer is in the 1.1...

... profile. Abstract Proper surface preparation is essential in obtaining adequate adhesion of fiberglass reinforced plastic (FRP) during laminate repairs on existing FRP substrates. In order to reduce the time required for the surface preparation of large areas, abrasive blasting was considered...

...Abstract Machine gun belt links have been zinc phosphate coated per DOD-P-16232 for over 40 years. The specification requires abrasive blasting as a pretreatment prior to phosphate coating. Decarburization requirements during heat treatment have resulted in the use of controlled atmospheres...

...Each type of coupon was cleaned by each of the six surface preparation methods. Comparisons between the abrasive blasted coupons and the UHP WJ coupons were made for each type of coupon. Also, comparisons between abrasive blasting and power tool cleaning were made. Most of the comparisons were made...
