DURMAT Laser-Like PTA Overlays

DURUM has more than 25 years of experience in the making and blending of PTA and laser cladding materials, also with 15 years of in-house development and manufacturing of a durable, reliable, mobile PTA unit. DURUMs PTA and laser cladding materials offer superior quality, repeatability, and performance. Currently available are nickel and cobalt based alloys, steels, carbide blends, and carbide matrix materials for custom blends. DURUM materials are gas atomized for consistent composition and repeatable results, then sized for the specific process. From new parts to repairs, we offer powders formulated specifically for your components. DURUM also offers PTA services using a wide range of deposit materials on and equally wide variety of substrates. With modern multi axis CNC and robotic automation will allow for laser like application, quality and precise placement of deposits on surfaces and edges. With DURUMS PTA services customers receive optimized process development for new applications.

DURMAT® FTC Powders

Fused Tungsten Carbide (FTC) is one of the hardest and most abrasion resistant materials used in modern wear resistance and tool technology.

FTC is the eutectic composition of WC and W2C. The average carbon content of our FTC is 3.8 – 4.1 wt. % and the phases can be estimated to be approximately 78 – 80% W2C and 20 – 22% WC.

Application: hard-facing metallic surfaces exposed to extreme mechanical load. In this case FTC should be used as a fine or coarser powder, which is embedded in the metallic matrix or is precipitated into hard alloys (surface coating by thermal spraying or welding). Using powder metallurgical processes, it is possible to produce parts of nearly any shape, which can contain hard materials or diamonds together with a metal binder and FTC (reinforcing the hardness of diamond tools). FTC equalizes the matrices between the different hardnesses of diamonds and binder in diamond drilling, grinding and honing tools. Excellent for deep well drilling tools and rods crusher jaws, mixers, concrete and stone saws, hot-pressed tools, screens & conveyors, extrusion housings, hard additives to diamond bits and saws.

Quality assurance:

The constant testing of our raw materials, production and pre-shipment procedures ensure the homogeneity of the compliance with the specifications of all powder grades that we deliver.
DURMAT® SFTC Powders

DURMAT® Spherical Tungsten Carbide (SFTC) is the most wear resistant Fused Tungsten Carbide we can offer.

These SFTC spherical fused tungsten carbide particles show a fine non-acicular structure with a higher hardness than conventional FTC (>3,000 HV0.1). The increased apparent density combined with a better flowability enable an increase of hard particles in wear resistant coatings and components produced by infiltration.

Using powder metallurgical processes, it is possible to produce parts of nearly any shape, which can contain hard materials or diamonds together with a metal binder and SFTC, reinforcing the hardness of diamond tools. FTC equalizes the matrices between the different hardnesses of diamonds and binder in diamond drilling, grinding and honing tools. Excellent for deep well drilling tools and rods, crusher jaws, mixers, concrete & stone saws, hot-pressed tools, screens & conveyors, extrusion housings and hard additives to diamond bits and saws.
