FortiPhySM UltraEnduranceSM Corrosion Resistant Tool Coatings Can Reduce Friction and Give Fluid Handling Components Added Toughness
Fluid handling components, such as pump gears, pistons, and sleeves, can wear prematurely and cause maintenance problems. Depending upon the application, component failure can cause safety problems as well.

FortiPhy corrosion resistant tool coating improves tool wear resistance and reduces friction to keep a variety of engineered components operating smoothly.
Engineers and designers must make assumptions regarding
the viscosity and lubricity of fluid, effectiveness of filtration,
operating temperature, and other factors, all of which must
be addressed during operation to prevent wear, galling, or
seizing of precision components. Filtration must remove abrasive
particles from the fluid to prevent piston scoring and pump
damage. Cooling systems must dissipate heat under all operating
conditions. The assumed lubricity of the fluid must not vary
from one “fill up” to the next. If any of these design parameters
are not met, precision components are at risk of failure.
Damage and wear of components typically lead to internal
leakage and pressure loss. Pumps work harder and harder until
they can no longer keep up with demand. Check or relief valves
may stick or work erratically. When components fail, production
stops until a replacement can be installed, lines bled, and
the system brought back on line.
Aircraft fuel pumps are a critical fluid handling application.
Fuel-lubricated pumps rely on the lubricity of the fluid to
prevent wear and reduce friction. When the lubricity is lower
than assumed by the designers, friction is increased and pump
wear can occur. Filtration failure and improper maintenance
procedures can put metal oxides and other abrasives in contact
with precision surfaces, accelerating wear and causing failure.
Diesel engines require extremely high fuel pressure to operate.
Fuel pump plunger pistons generate fluid pressure between
4500 and 9000 psi as diesel fuel is charged for cylinder fuel
injectors. This high pressure causes significant loading on
the plunger, which is lubricated only by the diesel fuel itself,
and at times, may allow metal-to-metal contact. This results
in premature wear, increased friction, and failure of pump
plungers and sleeves.
Even simple fluid handling systems such as those for delivering
paint, slurry, dough, or chemicals can be a maintenance bottleneck.
Anytime precision components wear out, they require manufacturing,
stocking, and replacement, thus reducing productivity.
