Improving our health,
our comfort and our natural environment
 The 21st Century presents Japan and the world
with the challenge and the hope of bringing
about a world that is healthier, more pleasant
and friendlier to the environment.
Some metals are regarded as being harmful
to human beings. On the contrary, titanium
and titanium alloys are used in various manufactured
goods because of their high biocompatibility
and lightweight nature. However ,because
of titanium`s unique characteristics, it
tends to cause sand sintering and wearing
out of parts made of other materials,especially
involving moving parts.
The Fresh Green process is the superior surface
modification method used for titanium and
titanium alloys that produces a durable,
hardened surface. Greater durability allows
application to a wider range of uses.
The Fresh Green process can do much to improve
our health, comfort and natural environment.The

High photocatalytic activity and exceptional
durability
Titanium material beyond titanium ...Fresh
Green
Fresh Green is a unique material that reinforces
titanium or titanium oxide surfaces by adding
carbon and oxygen molecules simultaneously.
Accordingly, the base material must be titanium
or titanium alloy.
Fresh Green film
fuses with the titanium
material,and therefore
the concentration
of oxygen and carbon
is gradually changing
within the boundary
layer between the Fresh
Green film and base
metal.
Hardness
The Figure1 shows Vickers hardness of the
Fresh Green film, other materials and plating
films. Vickers hardness of titanium, which
is the base material of Fresh Green, is only
117, lower than that of Type304 Stainless
Steel.
The Fresh Green film has a fairly high Vickers
hardness of 1600, much higher than nickel
plating and hard chromium plating which are
used to increase the surface hardness of
structural members.
Wear resistance
Fresh Green demonstrates high frictional
wear resistance. The figure 2 shows the results
of the wear test for Fresh Green film, other
materials and plating films. The amount of
friction measured on Ti-6Al-4V is with Fresh
Green film, is ~150mg. On the other hand,
Fresh Green film is only <10mg, lower
than gas nitriding and WC thermal spraying
which are evaluated as superior coating techniques
for anti-wearing.
Corrosion resistance property
Fresh Green proved to be highly resistant
to corrosion in tests for hardness, scratch
resistance and photocurrent density. The
tests showed that performance does not deteriorate
even after soaking Fresh Green in an acidic
(1M sulfuric acid) or an alkaline (1M sodium
hydroxide) aqueous solution for one week.
Application
With its unparalleled durability, the potential
applications for the Fresh Green process
are infinite.
While its applicability to the health, medical,
food and aviation industries is immediately
evident, there is no limit to the opportunities
this unique system offers for improving our
health, our comfort and our natural environment. |
