228	Method of toughening and modification of ceramic and ceramic product	US10381016	2003-03-20	US20030162483A1	2003-08-28	Hiroyasu Saka; Syoji Uchimura; Hideki Morimitsu
When a sintered body of ceramic is shot-blasted at normal temperatures to plastically deform the crystal structure of the shot-blasted surface to apply residual stress and is heat-treated to recrystallize fine cracks, dislocated cells in the grain boundary are formed, crystals are finely divided, and the fracture toughness is significantly improved. When the sintered body of ceramic is a thin product, an effective toughening can be attained by shot blasting both the front and back sides. After heat treatment, mechanical strength is significantly improved by removing a part of the modified surface layer by an abrasion treatment.
229	Processes for producing monolithic architectural cementitious structures having decorative aggregate-containing cementitious surfaces	US10058932	2002-01-28	US06610224B2	2003-08-26	Francis W. Sullivan

233	Methods of roughening a ceramic surface	US10027683	2001-12-21	US20030116276A1	2003-06-26	Edwin Charles Weldon; Yongxiang He; Hong Wang; Clifford C. Stow
Disclosed herein is a method of roughening a ceramic surface by forming mechanical interlocks in the ceramic surface by a chemical etching process, a thermal etching process, or a laser micromachining process. Also disclosed herein are components for use in semiconductor processing chambers (in particular, a deposition ring for use in a PVD chamber) which have at least one ceramic surface having mechanical interlocks formed therein by chemical etching, thermal etching, or laser micromachining. Ceramic surfaces which have been roughened according to the chemical etching, thermal etching, or laser micromachining process of the invention are less brittle and damaged than ceramic surfaces which are roughened using conventional grit blasting techniques. The method of the invention results in a roughened ceramic surface which provides good adherence to an overlying sacrificial layer (such as aluminum).

239	Metal matrix composite body having a surface of increased machinability and decreased abrasiveness	US09763688	2001-02-26	US06517953B1	2003-02-11	Brian E. Schultz; Michael K. Aghajanian
Often, metal matrix composites (MMC's) lack adequate machinability and possess excessive abrasiveness because hard ceramic materials, such as silicon carbide, are used as the reinforcement phase. To make a metal matrix composite body having a more machinable and less abrasive surface, an MMC comprising an aluminum nitride reinforcement is formed on the surface of the body. In one embodiment, a layer is provided to a permeable mass or preform at the surface at issue, the layer featuring at least a reduced loading of ceramic filler material, and sometimes no ceramic material at all. The reduced loading is achieved by incorporating a fugitive material into the coating layer. Molten matrix metal is caused to infiltrate the permeable mass or preform and the coating layer to produce a macrocomposite body comprising a metal matrix composite coating and substrate. The metal matrix composite coating layer is distinguishable from the metal matrix composite substrate material, both compositionally and in terms of resulting properties. Under spontaneous infiltration conditions, as defined herein, aluminum nitride forms in-situ in the infiltrated body, including the surface layer. The present coating technique, however, permits a thicker MMC surface layer to be produced than could be produced previously. The present MMC surface layer can be applied to virtually any reinforced or unreinforced aluminum or aluminum alloy body.
240	PREPARATION OF CONCRETE SAMPLES FOR MICROSCOPIC ANALYSIS	US09877449	2001-06-11	US20020187274A1	2002-12-12	Parviz Soroushian; Ali Nossoni
Concrete materials are impregnated with liquids which harden within concrete pores and microcracks, and develop a sharp contrast with the body of concrete in microscopic images. The impregnation process involves vacuum application to remove air from concrete pores and microcracks, followed by the introduction of liquids under pressure. The sharp contrast between the impregnated (and hardened) liquid and the body of concrete facilitates distinction of pores and microcracks in microscopic images for the purpose of automated image analysis.
