WebDropping in is a skateboarding trick with which a skateboarder starts skating a half-pipe by dropping into it from the coping instead of starting from the bottom and pumping … WebThe sputtering process starts with placing the substrate (the surface that requires a coating) in a vacuum chamber filled with inert gas atoms. The source material, which will transfer onto the substrate, then receives a negative charge and becomes a cathode. This causes free electrons to flow from the charged source materials.
