Abstract: PURPOSE: A method for treating surface of steel is provided to improve corrosion resistance and abrasion resistance by using an oxynitridation process. CONSTITUTION: A method for treating surface of steel comprises next steps. The ammonia and carbon dioxide are inserted in a furnace. Nitridation is performed in 500 ~ 600°C. After nitridation is completed, it is cooled in 500 ~ 550°C. The temperature of the nitridation is maintained in 500 ~ 550°C. It is oxidized under a vapor atmosphere. After it is cooled under room temperature after the oxidation process is completed.

Abstract: A manufacturing method of paste for plasticized electrode, using nano silver particles is provided to save the fuel by lowering a temperature necessary for plasticizing due to sinterability at the temperature lower than the melting point of the inherent metal. A manufacturing method of paste for plasticized electrode, using nano silver particles comprises a step for synthesizing the silver particle of nano-size consisting of silver powder of nano-size 5~20wt%, silver powder 50~65 wt%, lead-free Bi-based frit glass 3~9wt%, and a vehicle 21~27 wt% which is an organic solvent; and a step for mixing the synthesized silver particle of nano-size with the silver powder.
