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.
摘要翻译：已经显示和描述了通过使用超高压流体风扇喷射器使表面均匀粗糙化的方法。在优选实施例中，通过对一定体积的流体加压并迫使加压流体通过风扇喷嘴而产生超高压风扇喷射。风扇喷射器相对于要处理的表面以期望的距离定位，并且风扇喷射以选定的速率穿过表面，以均匀地粗糙化表面。在一个优选实施例中，对所获得的表面粗糙度进行定量并与期望的表面光洁度进行比较。然后可以相应地调整诸如马力和横移速率的操作参数以实现期望的表面光洁度。通过在将涂层施加到粗糙化表面之前通过使用超高压风扇喷射器使表面均匀且完全粗糙化，将提高表面和涂层之间的粘附。

摘要： A method for removing hard coatings from an underlying surface is shown and described. In a preferred embodiment, a nozzle having a particular geometry is used in a high-pressure fluid system to produce an ultrahigh-pressure fluid fan jet. The fan jet is traversed across a surface to be cleaned, thereby removing a layer of material without damaging the underlying surface. The effectiveness of the coating removal is improved by selecting an appropriate power distribution for the fan jet, a standoff distance between the fan jet and the surface to be cleaned, the speed with which the fan jet traverses the surface and the length and diameter of a settling chamber existing upstream of the nozzle.
