SealPlex2®
The SealPlex2® is used to surface seal and fill
the porosity in other materials. Surface treatments such as nitro-carburising
and tuftriding create a porous outer layer. This layer has excellent
liquid retention properties and when subjected to the SealPlex®
densification process, a single-phase ceramic layer is chemically
bonded into and over the porous outer layer.
The
SealPlex2® coating produced in this way is <5um thick with
a hardness up to 2,900 VPN. In addition to the significant increase
in surface hardness, corrosion resistance and frictional properties
are improved.
The
same techniques can be used to seal the surface of other porous
materials such as solid ceramics and sintered metals. If the impregnation
is vacuum assisted, full penetration of the porous structure can
be achieved and filled to produce a harder and stronger component.
Flame
sprayed coatings and electroplated hard chrome can also benefit
from the SealPlex2® densification process. These coatings are
by nature micro-cracked and porous and therefore susceptible to
interface corrosion problems. The penetration performance of the
SealPlex2® is so efficient that the micro-cracks in hard chrome
can be filled to improve both wear and corrosion performance.

The SealPlex2® process is capable of infiltrating
other surface treatments and coatings thereby sealing the corrosion
pathways down to the substrate.
There
is no apparent porosity.
