Bimetallic screw: There is an armouring layer on the top of screw
thread, or on the surface of all over the screw working surface. It
has a minimum contact wear ratio then it is running on the inside
of cylinder. The base material is one kind of high-strength and
weldable, nitridable metal. Between this armouring layer and the
base material, there is perfect material bonding. These two kinds
of material take different functions in hand, but form an uniform
whole.
