<P>PROBLEM TO BE SOLVED: To enhance corrosion resistance by forming an oxide film on a surface of an object to be worked by noble metal ions contained in a spray solution, when an entire surface of the object to be worked is subjected to WJP (water jet peening). <P>SOLUTION: Platinum group ions (at least one kind selected from Pt, Pd, Ru, Ir, Rh and Os) are dissolved in spray water, and the spray water is sprayed onto to the surface of the object to be worked, and the film containing platinum groups is formed. Alternately, the noble metal ions are dissolved in water where the object to be worked is disposed, and then WJP can be performed using pure water. <P>COPYRIGHT: (C)2013,JPO&INPIT |
