| A HARD, LOW-FRICTION, WEAR-RESISTANT SURFACE FOR HIGH LOAD APPLICATIONS |
Durillium N is applied as a diffusion process that significantly improves the wear and fatigue
life of ferrous metals. Durillium N is applied, depending on the alloy, at temperatures between
850° F and 1075° F. The process takes place in a fluidized bed or liquid furnace and is best suited to alloys that have been treated
and drawn at temperatures in excess of the process temperature. Materials that are heat treated and drawn at temperatures below the
application temperature of Durillium N will sacrifice some core hardness. This can generally be overcome
with the proper selection of alloys and heat treat cycles.
Once applied, Durillium N forms an inner diffusion/transitional layer(approximately 0.015 in. thick) of nitrides and carbides that supports
the outer surface layer. Because of the molecular structure of this transitional layer, chipping, flaking and peeling are almost impossible.
The outer layer (approximately 25 to 50 microns deep) is composed of epsilon nitrides and carbides of the constituent materials of the alloy.
Because of the porosity of this outer layer, an affinity exists for most dry film lubricants or polymer
topcoats useful in high load applications.
Durillium N has a surface hardness exceeding that of chromium plating and demonstrates considerably
greater wear and comparable corrosion resistance. It can be used with ferrous metals, cast
iron, and powdered metal applications without uncontrolled grain growth.
Durillium N has exceptional dimensional stability,
impact resistance and fatigue strength. Treated parts often can be bent or formed without danger of distortion to the surface. Durillium N
easily can be polished to "mirror back" the finish of the untreated part. Normal polishing procedures can return a diamond scale surface quality.
Durillium N is often used as a substrate for subsequent coating with WS2.

Durillium N, applied as a diffusion process, significantly improves the wear and fatigue life of cores,
inserts and gate areas in plastic injection molds exposed to high concentrations of glass, mineral or other abrasive filters.

that Durillium N is successfully being used on cutoff blades shearing plastic runners in high volume molding. Treated parts can be bent or formed
without danger of distortion to the surface. Durillium N easily can be polished to "mirror back" the finish of the untreated part. Normal
