BrazeCoatā Family of Products

BrazeCoatā M

With the BrazeCoatā M-Process, flexible mats, consisting of carbide powders as well as of filler metal powders (e.g. NiCrBSi), bonded by a polymer binder, are placed onto the substrate, the filler metal layer on top of the carbide layer. After preparation, the assembly is heat treated in a furnace process at approx. 1100⁰C (2010⁰ F) under protective atmosphere. The carbide layer, thereby, is infiltrated by the molten filler metal in the same operation joined to the substrate to be coated. In the BrazeCoatā M-process, the thickness of the resulting layers can be adjusted between 1mm (0.040 in.) to 3 mm (0.120)

BrazeCoatā S

With the BrazeCoatā S-Process the surfaces of components are protected against severe wear by depositing a carbide/hardfacing alloy suspension, which is heat treated and fused in a vacuum or hydrogen furnace. The thickness of the resulting layers can be adjusted between 0.05 mm (0.002 in.) and 0.3mm (0.012 in.).

The coatings are well bonded and show a low porosity (<1%). The surface as coated is very smooth, and for most applications final machining can be avoided. Due to the high carbide content of the coating layer, hardness values of over 65 HRC are obtained. Wear tests, under laboratory conditions as with components under service conditions in the field, showed improved resistance against abrasive wear over nitrided, borided or thermally sprayed layers.
