Abstract:
Introduction about Proposing Technology
- Nano-structure surface modification, known as Ultrasonic
Nano-Crystal Surface Modification (UNSM ) is an emerging and
very promising technology that can be used to solve fatigue
and wear/friction related problems.
- Unlike other technologies, nano-structured surface modification
directly improves the fatigue-strength of the surface by
simultaneously inducing relatively large and deep compressive
residual stresses, increasing the surface hardness, reducing
surface roughness, eliminating micro-cracks and white layers
on the surface, while also significantly reducing the coefficient
of friction. Given these benefits, the same technology can also
be applied gears, bearings, crankshafts, cylinder, and etc. In
fact, this technology has already been successfully applied to
the knives, rollers, and bearings extensively used by steel
industry.
