This is a really good question. There are two things to consider. Firstly, will the chemical composition change? the answer is no. both gold pieces will remain unchanged (this is in the nature of gold. It is seriously unreactive.)
But there is a second consideration. 9ct gold, being less pure than 18ct, is actually much harder. If your 9ct piece has a sharp edge, it may scratch or dent the 18ct piece.
But then again, almost anything else could similarly damage the softer gold. So don't worry.
My only concern is aesthetic. 9ct and 18ct gold are different colours and I don't think they go very well together. Wear either all 9ct or all 18ct.
