the direction of limiting frictional force is always opposite the direction of motion.

limiting friction acts tangential to the two surface in contact.

Answer:

Both are (top-down) engineering concepts. Both represent heuristic/phenomenological energy loss mechanisms used for mathematical convenience that are without fundamental descriptions. So a relationship between the two is not useful.

Using COF, μ and friction factors, fD lets you describe/predict a system's behavior conveniently and compactly, using mathematical equations and lookup tables. μ describes loss mechanisms in dry solids, and fD in fluids. They serve a mathematically similar purpose, and probably even share a lot of similar physics (both relate to thermal excitation and energy potentials of molecules at the bottom-end), but as engineering concepts, they are not related.
