PLATINUM Wear Plates
DURUM‘s family of Tungsten Carbide - Nickel base alloys exhibit superior resistance to abrasion and wear, retaining their hardness up to 600°C (approx. 1,000°F) in combination with excellent corrosion resistant properties. PTA - Plasma Transferred Arc is suitable for almost all cobalt and nickel based alloys as well as specially designed iron based alloys. Primary carbides in combination with those nickel, cobalt and iron based alloys improve the wear resistance remarkably compared to chromium carbide plates.
PTA is a true welding process, with deposits forming a metallurgical bond with the base metal. The dilution level is very close to those obtained by using the oxy-acetylene process. A further advantage of using the PTA process is the capability of producing thin edge surfaces. Together with the very low dilution (approx. 5 %) and the minimal distortion risk, the process is ideal for applications on wear-plates (wear-resistant composite sheets) or parts such as Fan Blades.

CP Wear Plates
The fabrication of the DURMAT® CP – plates (wear-resistant composite sheets) is carried out by use of a cored-wire welding process. The extreme wear resistance is achieved by use of high quality DURMAT® Flux Cored Wires consumables with high Chromium and Carbon content. The addition of complex carbides enables the formation of a high content of Chromium-carbides and special carbides, so that the required properties are achievable in accordance to the EN 14700 (group 10 former DIN 8555).
The characteristic, hyper-eutectic weld metal of the FeCrC hardfacing alloy consists of large, primary deposited carbides of the type M7C3, embedded in the eutectic matrix. The content of the primary carbides mainly affect the wear resistance. The increasing carbide content is related to steady rise of the Cr and C content. The addition of complex carbides e.g. NbC subsequently increases the wear resistance performance of the plates.
