An increase in the velocity of flowing media usually increases the corrosion rate
by sweeping away corrosion products and reducing the corrosion resistance of
the surface film . This may occur in a photographic process when spray nozzles ...

As a final operation , tanks should be passivated after fabrication to remove
contaminates that might have become imbedded in the surface . Passivating can
be done by immersing the tank in a 20 - percent ( by weight ) solution of nitric
acid at ...

Each material must be checked separately . Most lubricants are surface active
agents , and many also are hydrophobic , thus they can cause severe problems
with lithographic products . Each lubricant must be checked for use with
