<p>PURPOSE:To adapt to the environment easily by honing the surface of aluminum with a liquid material dispersed with alumina powder or sulfur powder thereby roughening the surface and then coloring the surface of the aluminum with impurities in the aluminum. CONSTITUTION:Surface of a member such as an aluminum pipe or an aluminum angle is subjected to honing with a liquid material dispersed with abrasive such as alumina powder and sulfur powder thus roughening the surface with average roughness of 0.5-5' and maximum roughness of 5-50mum. The abrasive may include silicon carbide, as well as alumina powder, having grain size of #60-300 and the sulfur is added by 0.1-10wt.% with respect to the abrasive, where the apparent volume of the abrasive and the sulfur is 15-40% with respect to the water. Honing is carried out under the pressure of 2-6kg/cm<2>. Surface of the aluminum member is colored with the impurities in the aluminum and the sulfur through the surface treatment. Thus treated aluminum member is employed in the fabrication of pipe jamper. According to the method, a jamper having brightness suitable to the environment can be fabricated easily.</p> |
