Worth, Eli H.Ī critical review of the experimental literature for measurements of the work functions of clean metal surfaces of single-crystals is presented.
Recommended values of clean metal surface work functionsĭOE Office of Scientific and Technical Information (OSTI.GOV)ĭerry, Gregory N., E-mail: Kern, Megan E. The solvent composition is nonhazardous so that when it is used to clean the surfaces of radioactive materials the waste in the form of paper or cloth wipes, lab coats and the like used in the cleaning operation is not considered to be mixed waste composed of a hazardous solvent and a radioactive material. and 2 to 25 volume percent of a polar solvent having a flash point sufficiently high so as to provide the solvent composition with a minimum flash point of at least 140.degree. The solvent composition consists essentially of a blend of nonpolar aliphatic hydrocarbon solvent having a minimum flash point of about 140.degree. Thompson, Lisa M.Ī solvent composition for displacing greasy and oily contaminants as well as water and/or aqueous residue from metallic surfaces, especially surfaces of radioactive materials so that such surfaces can be wiped clean of the displaced contaminants, water and/or aqueous residue. The solvent composition consists essentially of a blend of nonpolar aliphatic hydrocarbon solvent having a minimum flash point of about 140 F and 2 to 25 volume percent of a polar solvent having a flash point sufficiently high so as to provide the solvent composition with a minimum flash point of at least 140 F. Thompson, L.M.Ī solvent composition for displacing greasy and oily contaminants as well as water and/or aqueous residue from metallic surfaces, especially surfaces of radioactive materials so that such surfaces can be wiped clean of the displaced contaminants, water and/or aqueous residue. Nonhazardous solvent composition and method for cleaning metal surfaces In general, the salt content of thc cleaning agents ranged from 10 to 90%, preferably from 10 to 40% by weight and the balance of the composition comprises nitric acid of any strength from extremely dilute up to concentrated strength.
FLYCUT MILLING RUSTY SURFACE SERIES
The cleaning agents of the invention consist of aqueous nitric acid and an amhydrous nitrate salt of a metal which is lower in the electromotive series than the element of the deposit to be removed. Little, T.H.Ĭleaning fluids for removing deposits from metal surfaces are described. Metal surfaces are cleaned by contacting the surface with the cleaning solvent and then passivated by contact with aqueous solutions of citric acid or sodium nitrite or a combination of the two. nickle-iron alloys, contains sulfamic acid, citric acid, a solvent for hydrocarbon residues, and a surfactant. (Inventor)Ī cleaning solvent useful in the cleaning of metal surfaces, e.g. On lathes feeds and depth of cut can be more critical as they can have a big impact on the shape of the swarf, on some materials that can come off like pieces of string that wrap arround anything, turn the feed and depth of cut and the swarf can come off as tiny chips.Method for cleaning and passivating a metal surfaceĪlexander, George B.
just have a play and go from there, you'll learn what works for you and what doesn't. the interupted cut may need a slower speed as it will introduce vibration on lighter machines which can show as chatter on the parts you're making. finishing cuts will normally be light cuts so will have less heat generated at the cutting tip so will create less wear, as its the heat build up at the cutting tip which causes tool wear. home users will generally take lighter cuts which can extend tool life and you can run higher speeds for finishing cuts. Talking about milling at home (and flycutting) with hss cutters and bits, dont worry about feeds and speeds they are just general, and the ones quoted will normally be for industrial machines, when you would be assuming that the machines are rigid and want to remove the maximum amount of metal with the minimum tool wear.
