Abstract
Provided are coated metal, the metal having improved properties due to a novel coating, a coating-forming treatment solution for forming the novel coating, and a method for producing the coated metal that has the novel coating. The coated metal includes metal and a coating formed on the metal. The coating includes Si, P, and O, and at least one selected from the group consisting of Mg, Ca, Ba, Sr, Zn, Al, and Mn. The coating includes a compound having a NASICON-type crystal structure represented by the general formula MIMIV2(MVO4)3.
Claims1
A coating-forming treatment solution comprising:
- at least one metal phosphate selected from the group consisting of Mg, Ca, Ba, Sr, Zn, Al, and Mn;
- colloidal silica;
- and
- a compound having a NASICON-type crystal structure represented by the general formula MIMIV2(MVO4)3,
- wherein, in the general formula MIMVI2(MVO4)3, MI is at least one selected from the group consisting of Li, Na, K, 1/2Mg, 1/2Ca, 1/2Sr, and 1/4Zr, MIV is at least one selected from the group consisting of Zr, Ge, Ti, Hf, Cr+Na, Nb—Na, and Y+Na, and MV is at least one selected from the group consisting of P, As, and Si+Na.
