Abstract

PURPOSE: To form a Ti film with superior corrosion and heat resistances on the surface of an Al or Mg product by electroless plating by adding sulfuric acid or nitric acid to a titanium chloride soln., adding an alkali and a reducing agent to adjust the pH of the soln., and dipping the product in the resulting soln.
CONSTITUTION: Sponge Ti is put into a container holding hydrochloric acid, and water is added. This container is placed in other container filled with warm water, and by heating with an electric heater the Ti is dissooved to prepare a titanium chloride soln. To this soln. is added 5W20% sulfuric acid or 3W10% nitric acid, and the soln. is used as a titanium sulfate or titanium tetrachloride atmospheric soln. At this time, an alkali such as caustic soda or ammonia is added to adjsut the soln. to 3W7 or 3W11pH, and acetic acid or the like is added as a reducing agent to prevent decomposition and oxidation of the Ti plating soln. Al or Mg parts are dipped in this soln. to form Ti protective films with superior corrosion and heat resistance by electroless plating.
