Abstract: An abrasion wear resistant coated substrate product is described comprising a substrate and an abrasion wear resistant coating material comprising carbon, hydrogen, silicon, and oxygen. The abrasion wear resistant coating material has the properties of Nanoindentation hardness in the range of about 2 to about 5 GPa and a strain to microcracking greater than about 1% and a transparency greater than 85% in the visible spectrum. The coated products of the present invention are suitable for use in optical applications such as ophthalmic lenses or laser bar code scanner windows. In the method for making the products, the substrate is first chemically cleaned to remove contaminants. In the second step, the substrate is inserted into a vacuum chamber, and the air in said chamber is evacuated. In the third step, the substrate surface is bombarded with energetic ions and/or reactive species to assist in the removal of residual hydrocarbons and surface oxides, and to activate the surface.

Abstract: A plurality of particles include a first material. A coating including a second material is formed on surfaces of the particles, until a selected ratio of the volume of the coating relative to the volume of the particles is achieved. A plurality of particles, including the coated particles, are consolidated in a manner such that the particles are caused to be joined to each other, to form an article. The ratio of the volume of the coating relative to the volume of the particles is selected in a manner such that the article is engineered to have a selected volume fraction representing the volume of the second material in the article relative to the volume of the first material in the article. The first material, the second material, and the volume fraction are selected in a manner such that the article is engineered to exhibit a selected intrinsic property.

Abstract: A structure constructed to reduce the impact of visual imperfections having at least one visible surface which is covered by a first basecoat of an exterior water-based flat paint. The first basecoat is then covered by a layer of multicolor paint. Upon the incidence of the surface being visually marred, for example by graffiti, a second basecoat, similar in hue to the first basecoat, is applied over the portion of the surface that had been marred. A second layer of multicolor paint, similar in hue to the first layer of multicolor paint, is then applied over the second basecoat. The ability of the first basecoat to adhere to the structure may be enhanced by the addition of concrete glue to the flat paint. In addition the multicolor paint may be made reflective by the addition of glass beads or particles to both first and second layers of multicolor paint prior to its application.
