Long lasting conservation of tolerances
Parts under abrasive stress (such as wear rings, extrusion parts or brass calibration parts, etc.) can very successfully be coated with Lunac 2+ semi ceramic. This coating is very capable to withstand high abrasive, or combined abrasive/corrosive loads, due to the combined hardness of Hv 1230 for |
the metallic glass and alloy matrix and Hv 2200 for the modified ceramic content. An important additional aspect is the high freedom of coating parameters, such as (restricted) plating location capability, wide thickness and product dimension range, moderate process temperatures, smoothness etc.. |
Lunac 2+ coated brass calibration plates operational in a process line for titanium dioxide filled PVC window profiles. Besides the wear resistance (see figure below), Lunac 2+ delivers products with hardly ever any die line as well as black stripes. The heat conductance of these brass plates has not significantly changed. In practice these parts last for at least 7 years in case of intensive production instead of a few month.
These 2 calibration plates were tested under simultaneous conditions (equal sleeve vacuum and product speed). The white product (TiO2) processed on the Lunac 2+ coated plate wears out the calibration plate 80 times slower than the original brass plate.
