Since both types of material when the reaction. When some one To make the reaction is not completely break down and up, we can't measure about the size and depth of the micro-pattern.
The two materials on a reaction. At some point, The reaction was incomplete and a break down, we can not measure up to the size and depth of the micro-pattern.
Because the two materials when reacted. At some point, the reaction that is not complete, and the break down. We can't measure about the size and depth of the micro-pattern.
