    Abstract: A process capable of depositing a diffusion coating of uniform thickness on localized surface regions of a component. The process makes use of an adhesive mixture containing a binding agent that is consumed as part of the deposition process so as not to negatively affect the quality and uniformity of the resulting coating. The process entails mixing a particulate donor material containing a coating element, a dissolved activator, and a particulate filler to form an adhesive mixture having a formable, malleable consistency. The adhesive mixture is applied to a surface of the component, and the component is heated to a temperature sufficient to vaporize and react the activator with the coating element of the donor material, thereby forming a reactive vapor of the coating element. The reactive vapor reacts at the surface of the component to form a diffusion coating containing the coating element.

  • Patent number: 6562409
    Abstract: A low cost process for self-forming a uniformly adherent protective rare earth silicate coating on a silicon-based ceramic component for protecting the component against corrosive/erosive environments. The coating is self-formed by an oxidation process of a silicon-based ceramic associated with a reaction between a silica (SiO2) film layer on the surface of silicon-based ceramic and the rare earth oxide existing inside of silicon-based ceramic component.

  • Patent number: 6555175
    Abstract: A process for modifying the surface of a polymeric substrate is disclosed, wherein said process is comprised of contacting a surface of a polymeric substrate with a protic liquid or fluid containing a diazonium composition under such conditions that will effectively allow the reaction of the diazonium composition with the surface, resulting in the attachment of aromatic groups to the polymeric surface. The polymeric substrate contains aliphatic carbon-hydrogen bonds, while the protic composition is comprised of a diazonium complex formed by diazotizing an amino compound comprised of at least one amino group bonded to an aromatic group. Also disclosed are the products generated using the aforementioned surface modifications.

  • Patent number: 6514577
    Abstract: A surface treatment method that increases the wear resistance of contact portions of levers of a diaphragm spring in a clutch cover assembly and of a plate member that slides there-against is provided. The surface treatment method is applied to the contact portions of the diaphragm spring of the clutch cover assembly and to the plate member that slides there-against. In this method, the contact portion of the diaphragm spring and the sliding portion of the plate member are designated as treatment surfaces. The treatment surfaces are subjected to an electric discharge coating using a coating material such that the treatment surface is covered with a coating layer of approximately 50 &mgr;m or less and a diffusion layer is formed inside the treatment surface.

  • Patent number: 6500497
    Abstract: A method of producing a patterned magnetic nanostructure is disclosed. The method includes providing a substrate having a non-magnetic single layer or multi layer film that can be converted into a magnetic state by annealing and/or mixing. The method further includes positioning a mask having a desired pattern and resolution associated with the patterned magnetic nanostructure on or over the film. The method additionally includes subjecting the mask-covered substrate to a beam of radiation (focussed or unfocussed) having sufficient energy to locally anneal and/or mix the non-magnetic or weak-magnetic single-layer or multi layer film. Because of the mask effect, only the desired portions of the non-magnetic film are exposed to the beam of radiation. As such, the desired portions of the non-magnetic film are changed from a non-magnetic to a magnetic state to produce an array of magnetic elements in a non-magnetic matrix. The size of each magnetic element is dependent on the resolution of mask.

  • Patent number: 6451153
    Abstract: A method of preparing particles of a lignocellulosic material for the manufacture of a finished product, such as a particle board, includes the steps of chemically modifying the lignocellulosic material by impregnating the lignocellulosic material with a suitable anhydride in a non-aqueous solvent; applying to the particles of lignocellulosic material an adhesion promoter to promote the adherence of a thermoplastic resin to the surfaces of the particles of lignocellulosic material; and applying to the particles a thermoplastic resin in dry powder form, so that after the application of the adhesion promoter, the thermoplastic resin adheres to the surfaces of the particles of lignocellulosic material, the thermoplastic resin having been surfaced modified by irradiation or by fluorination; and removing any solvent present.
