No, it's totally different. They both scan the image with a window but the convolution multiplies the values in the window by the image values under the window and sums them up to get a new center pixel. The dilate just takes the maximum value in the window as the new center pixel.

Dilation is scanning the input image with a window and replacing the center location of the output image with the max of the input image inside the window.
