WebFriction stir processing (FSP) is considered a new solid-state processing technology for surface modification. Purpose: This study aims to strengthen the surface mechanical properties and promote the osteogenic capacity of the biomaterial by constructing a Ti-6Al-4V (TC4)/zinc (Zn) surface nanocomposites through FSP. ... Mishra RS, Ma ZY ... WebJul 11, 2014 · F = ma, and F = 0 are the mathematical representations of this statement. F = 0 implies the system's forces are in equilibrium, or that every action has an equal and opposite reaction. ... the box is in static equilibrium. So the net force on the box is zero. Once static friction releases, the frictional force on the box suddenly drops to a ...
