Abstract
Method of applying an high velocity oxygen fuel (HVOF)-resistant masking tape to the surface of a workpiece (112) such that multiple lengths of tape (116, 118) are abutted to one another to form butt joints (132), the butt joint (132) is then covered with additional lengths of tape (120).
Claims17
A method of applying a tape to a substrate, comprising:
- contacting an adhesive surface of a first high velocity oxygen fuel (HVOF) tape portion to a first area of a substrate, the first tape portion having first and second major edges, and a non-adhesive surface opposite the adhesive surface;
- contacting an adhesive surface of a second HVOF tape portion to a second area of the substrate, the second tape portion having first and second major edges, and a non-adhesive surface opposite the adhesive surface;
- wherein at least one of the first or second major edges of the first tape portion abuts at least one of the first or second major edges of the second tape portion, to create a butt joint;
- contacting an adhesive surface of a third HVOF tape portion to areas of the non-adhesive surfaces of the first and second HVOF tape portions, to cover at least a portion of the butt joint, the third HVOF tape portion having first and second major edges, and a non-adhesive surface opposite the adhesive surface.
