摘要： A method is given for obtaining recesses in a surface by etching. The obtained surface with recesses can be used for example in bearings.According to the invention, an etching method is given, wherein the depth of the recesses is controlled by forcing an etching fluid along the surface to be etched by means of a flow guiding template in places defined by this template.The etching rate in the recesses to be etched is controlled by adjustment of the flow velocity of the etching liquid and the slit height in the flow-guiding template.The recesses to be etched are deeper when the flow velocity of the etching fluid and the slit height are both higher.

摘要： CONCENTRATED ANION-DEFICIENT SALT SOLUTIONS ARE PREPARED OF THE ACTINIDE OXIDES PUO2, UO2, UO3 ANDU3O8 BY DISSOLVING ONE OR MORE OXIDES IN AN AQUEOUS SOLUTION OF THORIUM NITRATE AT A CONCENTRATION OF 4 MOLAR OR GREATER AND AT A TEMPERATURE OF 60* C. OR MORE. ANION-DEFICIENT SALT SOLUTIONS OF ACTINIDE METALS SO PRODUCED ARE USEFUL AS STARTING MATERIALS FOR THE MANUFACTURE OF CERAMIC NUCLEAR FUEL PARTICLES BY THE SOL-GEL PROCESS.

摘要： A METHOD FOR PREPARING PARTICLES OF METAL HYDROXIDE GELS BY TREATING A CONCENTRATED AQUEOUS SOLUTION OF AT LEAST ONE HYDROLYZABLE METAL SALT, THE HYDROXIDE OF WHICH IS ONLY SLIGHTLY SOLUBLE IN WATER, SIMULTANEOUSLY WITH AMMONIA AND HEAT. THE SOLID SUBSTANCE THUS OBTAINED IS SEPARATED, WASHED AND HEATED THEREBY CONVERTING THE SOLID SUBSTANCE TO METAL OXIDE PARTICLES. THE HYDROLYZABLE METAL SALT STARTING MATERIALS ARE CONCENTRATED SOLUTIONS ANION-DEFICIENT METAL SALT SOLUTIONS, HAVING A RATIO OF CONJUGATED BASE TO METAL LOWER THAN THAT OF THE NORMAL SALT. WHEN A NITRATE-DEFENDANT URANYL NITRATE SOLUTION IS MIXED WIT AN AMMONIA-RELEASING AGENT, THEN DISPERSED IN A HOT PHASE IMMISCIBLE WITH THE AQUEOUS PHASE, THE RESULTING SOLIDIFICATION PRODUCES MICROSPHERES OF URANYL NITRATE, WHICH ARE USEFUL AS FUEL CELLS IN NUCLEAR REACTORS.

摘要： AN EVEN, TENACIOUS BLACK COATING OF NICKEL SULFIDE IS APPLIED TO THE SURFACE OF ALUMINUM ALLOYS BY IMMERSION OF THE ALLOY INTO AN AQUEOUS BATH CONTAINING FROM 35200 G./L. OF NICL2.6 AQ AND FROM 0.03-0.25 MOLAR OF THIOCYANATE IONS FOR A PERIOD UP TO 5 MINUTES ACCORDING TO THE PROCESS DISCLOSED. PREFERABLY THE AQUEOUS BATH ALSO CONTAINS FROM 10-20 G./L. OF NH4CL, FROM 8-12 G./L. OF KCNS AND IS MAINTAINED AT A PH IN THE RANGE OF 3-4.
