| 243 | Method of applying concrete-based material | US09730526 | 2000-12-05 | US20020102354A1 | 2002-08-01 | Eduardo Ramirez de Arellano |
| A concrete-based mortar is prepared for application on the exterior of a concrete building or other structure. The drying time of the concrete-based mortar is reduced by addition of an accelerant compound. After the concrete-based mortar sets on the building or other structure, an exterior skin of the concrete-based mortar is removed. This provides an even and attractive surface while reducing the amount of labor time required to complete the application. | ||||||

| A fiber-organic composition includes from about 5% to 50% by volume of uniformly dispersed, non-planar or three dimensionally random oriented inorganic fibers or whiskers, and a thermoplastic material such as paraffin wax. The composition also includes surfactants to promote wetting and dispersion of the inorganic fibers or whiskers. These materials are subjected to high shear mixing to form a uniform randomly oriented three-dimensional dispersion of the inorganic fibers or whiskers. After molding the mixture in such a manner so as not to disrupt the uniform, three-dimensional orientation of the fibers or whiskers, a majority of the thermoplastic material is removed leaving a shaped body or preform having sufficient strength for handling. The shaped body or preform can then be infiltrated with molten metal or the like to form a metal matrix composite. | ||||||

| A method for tailoring or patterning the surface of ceramic articles is provided by implanting ions to predetermined depth into the ceramic material at a selected surface location with the ions being implanted at a fluence and energy adequate to damage the lattice structure of the ceramic material for bi-axially straining near-surface regions of the ceramic material to the predetermined depth. The resulting metastable near-surface regions of the ceramic material are then contacted with energy pulses from collapsing, ultrasonically-generated cavitation bubbles in a liquid medium for removing to a selected depth the ion-damaged near-surface regions containing the bi-axially strained lattice structure from the ceramic body. Additional patterning of the selected surface location on the ceramic body is provided by implanting a high fluence of high-energy, relatively-light ions at selected surface sites for relaxing the bi-axial strain in the near-surface regions defined by these sites and thereby preventing the removal of such ion-implanted sites by the energy pulses from the collapsing ultrasonic cavitation bubbles. | ||||||

| A coated carbon body having improved resistance to high temperature oxidation and a method for producing the coated carbon body are described. The coated carbon body comprises a carbon body, an intermediate glass forming coating within said converted layer, and an outer refractory coating on the intermediate coating. The body has a converted porous layer formed by etching and reacting the body with gaseous boron oxide and the resulting converted layer contains interconnecting interstices and boron carbide formed by the reaction of the boron oxide and the carbon body. The method comprises contacting a carbon body with boron oxide at an elevated temperature sufficient to cause the reaction between the carbon body and boron oxide to form a converted porous layer which contains interconnecting interstices in the body and boron carbide and then applying the intermediate glass forming coating over the converted layer and an outer refractory coating over the intermediate coating. | ||||||

| The surface of a blank for a textured amorphous carbon substrate is polished in a surface with a predetermined surface roughness, and then the blank with a polished surface is heated at a predetermined temperature in an oxidizing atmosphere to form minute irregularities in the polished surface through a reaction expressed by C+O.sub.2 =CO.sub.2 so that the surface is textured in an appropriate surface roughness. A randomly textured amorphous carbon substrate has a randomly textured surface with a surface roughness Ra in the range of 20 to 100 .ANG. and the ratio Ra.sub.2 /Ra.sub.1, where Ra.sub.1 is the surface roughness with respect to a circumferential direction, and Ra.sub.2 is the surface roughness with respect to a radial direction, in the range of 0.75 to 1.25 .ANG.. A concentrically textured amorphous carbon substrate has a concentrically textured surface with a surface roughness Ra in the range of 30 to 100 .ANG. or in the range of 40 to 200 .ANG., and the ratio Ra.sub.2 /Ra.sub.1 of 1.75 or greater. | ||||||
| 256 | Method for reducing metal content of self-supporting composite bodies and articles formed thereby | US794607 | 1991-11-15 | US5232040A | 1993-08-03 | William B. Johnson; James C. Wang |
| This invention relates generally to a novel method for removing metal from a formed self-supporting body. A self-supporting body is made by reactively infiltrating a molten parent metal into a bed or mass containing a boron source material and a carbon source material (e.g., boron carbide) and/or a boron source material and a nitrogen source material (e.g., boron nitride) and, optionally, one or more inert fillers. Once the self-supporting body is formed, it is then placed, at least partially, into contact with another material which causes metallic constituent contained in the self-supporting body to be at least partially removed. | ||||||
| 257 | Method and apparatus for treating a surface of granite with a high temperature plasma jet | US775976 | 1991-11-01 | US5211156A | 1993-05-18 | Jerzy Jurewicz; Maher Boulos; Clermont Roy |
| The method and apparatus treat a surface of natural rock or artificial stone-like material to give to this surface an attractive finish. A high temperature jet of plasma and a high speed jet of cooling fluid are projected onto the surface to be treated. The two jets are moved on the surface at a given speed with the jet of cooling fluid following the plasma jet. The speed of movement is selected so that the high temperature plasma jet heats only a thin superficial layer of rock or stone-like material. As the jet of cooling fluid follows the jet of plasma, it suddenly cools the thin superficial layer just heated by the plasma jet to cause a thermal shock which bursts particles of rock or stone-like material at the surface thereof, and blows these particles off the rock surface. | ||||||

| A process is provided for working a base material which essentially consists of a ceramic material. The process includes an irradiation process of irradiating a laser beam or an electron beam to the base material in order to form an affected portion having cracks in the base material and a removing process for removing the affected portion. The ceramic material includes an oxide ceramic material (for example, alumina and forsterite) and a carbide ceramic material. The shape and the depth of the portion to be worked are controlled by the scanning of the laser beam or the electron beam. The removing process can include any one of the processes of vibrating the base material, applying a thermal shock to the base material and etching the base material. In accordance with the present invention, a base material which essentially consists of an oxide ceramic material or a carbide ceramic material can be worked with high aspect ratio and in a shorter period of time than in a conventional process. | ||||||

| In a process of dressing a refractory structure, a comburent gas stream carrying a mixture of particles is projected against the site to be dressed. The particle mixture comprises particles of one or more elements which is or are oxidizable to form one or more refractory oxides ("fuel particles") together with refractory oxide particles and the fuel particles are caused or allowed to burn during projection. The mixture further incorporates a fluxing agent, the fluxing action of which is such that under the heat released by combustion of the fuel particles, the refractory structure becomes softened to an extent such that the structure becomes dressed by removal or displacement of material thereof under the mechanical action of the impinging stream.Suitable fuels include very fine particles of aluminum and/or silicon. Suitable fluxes include fluorides and compounds of metals other than those whose oxides are projected in the mixture, for example alkali metal compounds, especially salts selected from borate, sulphate, carbonate and phosphate. | ||||||
