  • the coated abrasive article can be in the shape of conventional coated abrasive articles, for example, belts, discs, sheets, and strips. But the most preferred shape is a file.
  • the preferred embodiment of the file is depicted in Figs. 1 - 3 and is generally referenced by the numeral 10.
  • the flexible file 10 can be used for filing or cleaning both delicate and heavy-duty mechanical instruments M. Furthermore, since the file 10 is flexible, it can be easily bent around objects of various shapes and designs, reaching even the most hard to reach places. And though the file 10 is primarily for use as a slot file, it may be employed on a variety of materials such as plastics, wood, or almost any other substance, though it is particularly well suited for use on metals. Thus, the flexible file 10 is a truly multipurpose instrument, suitable for even complex scientific and mechanical devices . The file is particularly suited for use in the textile industry.
  • the flexible file 10 comprises an elongated, generally rectangular body having broad, flat, opposing faces, each generally 12.
  • the file 10 comprises a metal substrate 16 over which a layer of abrasive particles 14 is deposited, as best appreciated by the area fragmented or broken away.

  • the metal substrate 16 may be of any size, shape, and thickness.
  • the metal substrate may be any sufficiently hard and flexible ⁇ metal such as steel, steel alloys, stainless steel, and titanium. Nevertheless, any sufficiently hard and flexible metal may be used. And so softer metals, such as copper, should preferably be avoided to ensure that the file 10 has a tough edge for cutting.
  • a strip of steel is unreeled from a roll, sandblasted, sheared to length, and successively stamped to form a plurality of individual metal blanks .
  • the metal blanks are then suspended in a tank and washed using a commercial type washing solution.
  • the outer surface of the metal substrate 16 is texturized to increase its surface area. It has long been recognized that roughening materials increases surface area for adhesion. By using specific methods to create a texturized surface, an irregular topography is created, which, when selectively coated with an outer protective layer or finish, provides a stable, durable, and abrasive surface.
  • the surprisingly good results obtained by the present invention may be ascribed to the degree of roughening of the surface and the durable, protective, outer layer deposited thereon.
  • the chemical and physical characteristics of the metal substrate 16 determine which texturizing process should be used. Nevertheless, it should be understood that this specification embraces any means for texturizing, whether by the removal, treatment, or deposition of material substances in relation to the outer layer of the metal substrate 16, including sputter etching.
  • chemical etchants will be employed to create the texturized surface. Again, the chemical and physical characteristics of the metal substrate 16 will determine the appropriate etchants. Examples of chemical etchants include ferric chloride, ammonium persulfate, and sulfuric, hydrochloric, and nitric acid. Pretreatment to remove surface contaminants is especially important prior to chemical etching because overlying substances will interfere with inter-atomic adhesion.
  • the metal substrate 16 is texturized by being mechanically stamped. With stamping, progressive dies can be used to mechanically remove unwanted metal from the exterior surface of the substrate 16.
  • the substrate 16 may be laser machined, photolithographed, or scraped in any manner to increase surface area.
  • the step of stamping includes any physical method to increase surface area such as re-shaping the substrate under pressure and heat to form a texturized surface using an appropriately pitted, nano-pitted, or crenulated die.
  • One such surface could include a crenulated surface, which may be defined as having an irregular wavy or serrated outline.
  • the metal substrate 16 is texturized by being sandblasted.
  • the sandblasting composition may be applied at a predetermined angle to the surface of the metal substrate 16. While corundum (aluminum oxide) has been found to produce the required result and is the preferred sandblasting material, it should be understood that this specification does not exclude any similarly hard material . Corundum is the second hardest substance after diamond and creates microscopic valleys in the metal substrate 16 when used as a sandblasting material.
  • the sandblasting material may contain any additional chemical agents for insuring its consistent application to the metal substrate 16 so as to provide a surface free of unwanted or excessive cratering, pitting, or uneven texturizing.
  • the standard abrasive blasting system comprises a compressed air or gas source, a pressurized media vessel having standard pressure gauges, pressure regulators, media valves, a media orifice plate, air lines, and media exit lines.
  • the metal substrate 16 is coated with a layer of abrasive particles so as to improve wear-resistance.
  • the abrasive particles are harder than the metal itself.
  • the deposition bath comprises at least one nickel salt, such as nickel sulphate (NiS0 4 ) or nickel chloride (NiCl 2 ) , and a suspension of particles of a carbide.
  • the coating of nickel and particles of carbide are preferably electrolytically deposited, by the application of an electric current. Electroplating is advantageous in that the timing and therefore the thickness of the abrasive layer can be precisely controlled. In an alternative embodiment of the invention, electroless plating may be used.
  • the flexible file 10 may also have multiple layers of abrasive particles or electrodeposited metals.
  • the abrasive granules on one side of the file 10 may be selectively applied so as to be coarser or more dense than the granules on the other side of the file 10.
  • the thin end edges, generally 18, of the file 10 are also preferably coated with granules.
  • the granules are relatively coarse, sharp, and jagged so as to present a good abrading surface.
  • the abrasive material impregnated or deposited on the texturized surface may be selected from the group consisting of metals, borides, diamond, nitrides, silicides, and particles of a matrix metal.
  • the end portions, generally 20, of the file 10 are free, and the area between the end portions 20 is unsupported, so as to maintain a high degree of flexibility, allowing the file band to be deformable to accommodate the curvature of items of different shapes.
  • This flexibility in addition to the inherent flexibility of the metal substrate 16, is advantageous when working with materials of many different types.
  • the flexible file 10 may be provided with holder-engaging means such as a conventional saw frame so as to facilitate the task of shaping materials such as ceramics and fiber glass.
  • the file may also have a cap or other gripping structure frictionally embracing an end thereof; the cap may be comprised of any material, but is preferably made of plastic or a similar polymeric substance .

  • the preferred embodiments of the invention provide a multipurpose flexible file and a method for making the file.
  • the file is an abrasive device.
  • the file is an abrasive article comprising frictional granules electrodeposited onto an underlying, flexible structural base.
  • the same principle may be used in coating wet rocks for sharpening knives or scissor blades.

Abstract

L'invention concerne une lime (10) souple et son procédé de fabrication. Ladite lime (10) présente une surface de frottement ou de raclage conçue pour abraser des métaux, des plastiques, du bois ou quasiment toute autre matière. Elle convient particulièrement bien pour un limage de précision. La lime souple, qui comporte notamment un corps allongé, généralement rectangulaire, à faces opposées larges et plates, est formée d'un substrat métallique (16) revêtu d'une couche de particules abrasives (14). Le procédé consiste, dans une première étape, à produire un substrat métallique dur et souple, dans une deuxième étape, à texturer le substrat métallique afin d'en augmenter la surface efficace. Par des procédés chimiques ou mécaniques, destinés à créer une surface particulièrement texturée, on crée une topographie de surface suffisamment irrégulière qui produit, une fois sélectivement revêtue d'une couche ou finition de protection extérieure lors de la troisième étape du procédé, une surface stable, durable et abrasive.
