At NCT, we take pride in finding the protective coating & process that best match your individual application
Our PVD coating or plasma
ion nitriding process will improve your components performance
on the track. Our ion plating PVDcoating processes provide exceptional adhesion, particularly
when compared to those applied by conventional plasma spray or
wet-bath methods. The ionization from the evaporation sources
and increased surface energy improves film adhesion, density and
uniformity.NCT utilizes two ion plating processes to deposit our high performance
thin film coatings. In the cathodic arc process, large area cathodes
are used to produce a uniform coating throughout the entire chamber.
The cathodic arc is highly versatile process and deposits a film
with exceptional adhesion. Our hollow cathode electron beam process
produces the smoothest high density films available in the PVD
coating industry. This process will rotate and traverse the product
over the evaporation source to ensure uniformity throughout the
entire carousel. This guarantees consistent performance, order
after order. The plasma ion
nitriding process used by NCT produces uniform casehardened
layers that improve wear resistance, lower the tendency to gall
and extend the fatigue life of your components.
The plasma process can be performed at a lower temperature which yields stability and minimizes the probability of distortion. Manipulating the power and pressure during our process controls the level of plasma energy so it can be customized for the best result. Slow cleaning during the heating cycle produces purest possible surface, allowing a uniform diffusion of nitrogen into the steel to occur.
The ion bombardment portion of the process is carefully controlled so that no damage to the surface occurs. The hardness and case depth of the nitride layer will vary greatly depending on the alloy being nitrided. Our business depends on our ability to guarantee a superior result: uniform protective coatings, and a process which can be exactly and infinitely replicated. At NCT, we provide individualized solutions enabling you to perform beyond standards.
