| Research Abstract |
We found a new procedure to make a surface porous structure by oxidation and reduction processes for a metal substrate. If the distribution of pore size has gradient from the bulk to the surface of the substrate, we can penetrate glass or ceramics into those pores and solidify them to make a new joint material which has high joint strength because of mutual penetration of two phases. Finally, we found some adequate experimental conditions to make the above porous surface structure.
