Method for preparing surfaces with an ultrahigh-pressure fan jet |
摘要 |
A method for uniformly roughening a surface through use of an ultrahigh-pressure fluid fan jet has been shown and described. In a preferred embodiment, an ultrahigh-pressure fan jet is generated by pressurizing a volume of fluid, and forcing the pressurized fluid through a fan jet nozzle. The fan jet is positioned relative to the surface to be treated at a desired distance, and the fan jet is traversed across the surface at a selected rate to uniformly roughen the surface. In a preferred embodiment, the achieved surface roughness is quantified and compared to a desired surface finish. Operating parameters, such as horsepower and traverse rate, may then be adjusted accordingly to achieve the desired surface finish. By uniformly and completely roughening a surface through use of an ultrahigh-pressure fan jet prior to applying a coating to the roughened surface, adherence between the surface and the coating will be improved.
