Abstract
A coated substrate and a process for forming the coated substrate, including a first lubricious coating layer overlying the substrate, the first lubricious coating layer including a first lubricant providing to the first lubricious coating layer a first coefficient of friction; and a second lubricious coating layer overlying the first lubricious coating layer, the second lubricious coating layer including a second lubricant providing to the second lubricious coating layer a second coefficient of friction, in which the second coefficient of friction is greater than the first coefficient of friction.
