摘要： PROBLEM TO BE SOLVED: To perfectly dissolve away molten salt on the object to be treated by hot water rinsing in a cleaning stage even as for a part with a complicated shape by performing displacement washing in a salt bath having a specified composition after salt bath nitriding treatment, and to further improve the level of its corrosion resistance by the displacement washing with the salt bath having a specified composition. SOLUTION: A metallic member is dipped into a salt bath comprising Li + , Na + and K + as cation components and CNO - and CO 3 -- as anion components to form a nitride layer on the surface thereof. In the method where alkali hydroxide, combined water, free water, moist air or the like are added to or impregnated into a salt bath to strengthen the oxidizing power of the salt bath, so that a nitride layer is formed on the surface of a metallic member, and simultaneously, an oxide layer is formed on the outermost surface thereof, the metallic member is dipped into a salt bath comprising alkali nitrate in the stage subsequently to the nitriding salt bath treatment.

摘要： PROBLEM TO BE SOLVED: To provide a surface hardening method for an engine valve harmless for the environment instead of a salt bath nitriding method (Tufftride TF-1) accompanied by cyanogen waste water and cyanogen-containing industrial waste and a fluoride film activation type gas soft nitriding method requiring harmful exhaust gas treatment equipment.
SOLUTION: In the surface hardening treatment method for an engine valve, a gaseous mixture comprising a carbon feeding compound (s) and a nitrogen feeding compound (s) being gas at 150°C under the atmospheric pressure as essential component is heated to ≥200°C under the atmospheric pressure; owing to the catalytic action of an engine valve as the metallic material to be treated, a metallic inner wall of a furnace and/or a metallic catalyst installed in the furnace, HCN is produced in the above atmosphere; the produced HCN is made to act on the surface of the engine valve to modify and activate a passivated film on the surface; and, successively, gas nitriding and/or gas nitriding-carburizing is performed at 400 to 600°C.

摘要： PROBLEM TO BE SOLVED: To provide an ammonia decomposition method not having a defect such that chloramine is generated if pH is lower than 5.6 in a conventional discontinuous method for decomposing ammonia by hypochlorous acid and a reaction speed becomes slow if pH exceeds 9.5. SOLUTION: When a condition with pH 10-14 and a temperature from 50 deg.C to a boiling point is set in a method for treating an ammonia-containing waste liquid with hypochlorite, ammonia is oxidized to be decomposed into nitrogen and water.

摘要： PROBLEM TO BE SOLVED: To solve the problem that conventional methods for separating valuable metals from a metal cyanide-containing solution produce solid cyanides, generate gaseous HCN and cannot be applied to a solution having a high concentration of cyanides. SOLUTION: A hypochlorite salt is continuously added to a metal cyanidecontaining solution in which cyanides of Ni, Cu, Zn and Au and/or Ag are dissolved, under alkaline conditions within the temperature range from 60 deg.C to a temperature below the boiling point of the solution to precipitate Ag as a chloride and Ni, Cu and Zn as oxides or hydroxides and to dissolve Au as chloroaurate in the solution.
