WMV lunac1

Specific Lunac 2+ features:

1. This hard crack free coating is highly abrasive, fretting and adhesive wear resistant (adhesive wear test results: 23 N at 0.7 m/s; the combination Lunac 2+/Lunac 2+ is 19 times more wear resistant than the combination hardened DIN1.2379/hardened DIN 1.2379.
2. This coating is virtually immune to fretting/cold welding/galling problems in case of non-lubricated conditions!
   Therefore this coating is preferably applied to heavily loaded/non-lubricated parts in relative motion.
3. Wear of the non coated opposing parts reduces significantly as well (especially in water) .
4. Very good abrasive wear/seizing resistance (comparable with sintered ceramic materials).
5. 30% reduced dry coefficient of friction compared to steel DIN 1.2379 on steel 1.2379.
6. Good corrosion resistance in (sea)water on smooth surfaces.
7. Lunac 2+ resists oxidative wear (contact corrosion) very well.
8. Steel cylinders coated with Lunac 2+ are similar to
   ceramic plated cylinders in tribological perspective.
9. Moisture will tarnish the Lunac 2+ surface.
10. Complies fully with the RoHS standard.
11. Relatively tough.

General Lunac system features:

- Lunac can establish a full (welding quality) substrate bond. Lunac coatings can be applied to:
-- almost every kind of (stainless) steel or cast iron (up to HRc 50).
-- nearly all copper alloys
-- aluminum with restrictions

- The throwing power in complex / deep structures is approximately 6 times
better than the throwing power of hard chromium (less edge build up).

- Starting at 23 µm (0.0009") these coatings are completely
closed and contain compressive stresses.

- The duplo coating system passes, applied to pore free construction steel
with the intermediate technical nickel coating, the ASTM B117 1000 hours
Neutral Salt spray test without any rust spot formation (rating 10).








Hydraulic strand jack pistons coated with 55 µm / 2.2 mil Lunac 2+. The Lunac 2+ coating proved to be a very economic concept to obtain long lasting wear, scratch and corrosion resistance. After plating very little effort is needed to aquire the smooth surface (Ra= 0.2 µm).

The governor axles in the Kornwerderzand lock doors of the major northern Dutch IJsselmeer dam have been Lunac 2+ coated because of the corrosion resistance, abrasive wear resistance and shock resistance. Moreover the Lunac 2+ coefficient of friction in water contact conditions can be exceptionally low.
