What we can do
RAM® coatings based on tungsten carbides have a very high hardness: up to 70 to 72 HRC. The process uses a supersonic flame by burning hydrogen and oxygen. This is a pure combustion, so that the combustion gases do not pollute the coating, and undesirable chemical reactions are avoided. By applying a deoxidising flame, undesirable oxidation can be avoided as well. This is a cold process, so no thermal treatment of the substrate is required.
Excellent wear resistance and increased service life. Super-finish is possible with Ra values <0.01 μm. No risk of thermal deformation, and this procedure can be applied to a finished part without risk of changes to size or shape. Environmentally friendly process and sustainable solution.
For new parts
The preventive application of RAM coatings to the wear & tear areas of new parts will increase their life span significantly. Typical applications are the bearing surfaces of seals, gaskets and slide bearings of machine parts. More and more, RAM coatings are also being used in static devices for protection against erosion or abrasion.
Worn out shafts, bearing-areas, and parts can be permanently restored by means of RAM coatings. In addition to dimensional repair, wear resistance can be increased by the right choice of applied layer. In this way, the life span of a repaired part can be significantly improved.
