| description | PURPOSE:To form a good underlying film for painting without requiring a plating liquid by forming a Zn film by a shot blasting method on the surface of steel products then treating the film with a phosphate treating liquid contg. Ni ions. CONSTITUTION:The pulverized particles of a Zn (alloy) coating metal such as Zn or An alloy are sprayed by the shot blasting method to the surface of the iron and steel products to form the film of the Zn (alloy) at the same instant when the oxide films such as rust and black skins on the surface of the steel products are removed. The film is thereafter subjected to the surface prepn. using an aq. soln. of colloid titanium according to need. The film is then treated by using the phosphate treating liquid added with about 0.05-10g/l Ni ions to form the phosphate film thereon. The spacings among the pulverized particles of the Zn (alloy) are filled by the phosphate crystals and the film having the good corrosion resistance is formed as the subtrate for painting by the above- mentioned treatment method. |
