Lunac (alloy and trans-ceramic coatings)
Encyclopedia
Lunac refers to two kinds of coating developed by the WMV laboratories. Lunac 1 is a metallic glass coating with particularly good non-stick properties, used mainly for coating the insides of die
s used in plastic
molding
; Lunac 2 + is a very hard
(up to Hv=2300) trans-ceramic coating, resistant to abrasive wear, used for coating moving machine parts which cannot otherwise be lubricated.
The coatings are fairly thick, from 50 to 250 micrometre
s. The composition is not described on WMV's website, and the only provider of coating services is WMV.
Research beginning in the late 1990s revealed other new features such as a remarkable friction reduction in some seal-coated axle systems in water. Coefficient of friction down to 0.011 can be obtained in combination with some plastics.
Die (manufacturing)
A die is a specialized tool used in manufacturing industries to cut or shape material using a press. Like molds, dies are generally customized to the item they are used to create...

Plastic
A plastic material is any of a wide range of synthetic or semi-synthetic organic solids used in the manufacture of industrial products. Plastics are typically polymers of high molecular mass, and may contain other substances to improve performance and/or reduce production costs...

Vickers hardness test
The Vickers hardness test was developed in 1924 by Smith and Sandland at Vickers Ltd as an alternative to the Brinell method to measure the hardness of materials. The Vickers test is often easier to use than other hardness tests since the required calculations are independent of the size of the...
