Benefits of piston skirt coating:
* Frees up horse power normally lost to friction.
* Provides back-up lubrication if the primary
lubrication has gone
* Reduces wear which increases engine life
* Meet the demands of high revving, short
piston skirt and long rod motors
* Reduces heat that can cause galling
and seizing
* Produces tighter piston-to-wall clearance

Steel is roughly twice as strong as ductile iron.
Steel is harder, has a higher tensile strength and higher
fatigue strength that either ductile or grey cast iron.
Steel rings provide:
* Better breakage resistance.
* Improved heat resistance.
* Better mechanical stress resistance.
* Reduced ring side wear.
* Reduced groove side wear.
* Longer service life.

52. PVD Coating Equipment - Japanese Design
SAM introduced the PVD coated (Physical Vapor
Deposition) compression ring for engines.
The RINGs are made of Nitrided Steel and has a
Ceramic Coating (chromium nitride) MFI, which is
applied by means of the PVD method.
SAM also has now succeeded in additionally
depositing the chromium nitride coating on the
nodular cast iron ring material.
Result :-
* lower friction
• offering maximum wear resistance
engines with lower output
* cost-efficient compression ring solution
• The PVD coating are the lower friction
coefficient and the excellent tribological
compatibility with the materials of the cylinder
running surface.
Properties:-
* Engine friction and cylinder wear can be
reduced.
* A low-friction ring pack reduces fuel
consumption
PVD process is very environment-friendly.
