Technocore Ni® 1.6 mm

Metal cored composite wire

Metal-cored wire made with spherical cast tungsten carbide (Spherotene®, hardness 3000HV) in a nickel-based matrix for optimum abrasion resistance in severe environment conditions. The deposit offers a very good resistance to wear. Re-application of worn tool can also easily be done. The low heat input helps reducing tungsten carbide particles dissolution.

FIELDS OF APPLICATION

Various industries such as drilling industry, brick and clay, steel industry, dredging, recycling industry .

WHY LaserCarb®

Numerous industries use tools that require high resistance to abrasion and erosion. The LaserCarb® process is a hard surfacing process that adds an anti-abrasion material to the wear parts. The LaserCarb® process resolves numerous problems caused by welding.

PRINCIPLE

The process consists of using the energy of a Laser beam to melt the deposition powder (Ni-Cr or other material) on the part. A weld occurs between the deposit and the base metal.

BENEFITS

The hardness and toughness of Spherotene® (cast tungsten carbide spheres produced by Technogenia) united with the unique properties of a high energy laser produces a weld deposit. The cast spheres exhibit hardness of 3000 + 500 HV, and they pack close together to produce a dense deposit. The spherical shape also increases toughness in the carbide grain and the overall deposit.

Use of powders based on cast spherical Tungsten Carbide Spherotene®

• High hardness: 3000 HV ‡ 500 • Spherotene® is not affected by LaserCarb®

• Low heat affected zone (0.030") • Almost total absence of porosity

• Large range of thickness deposit • Metallurgical bond

APPLICATIONS: 

Mining, Geodrilling, Tunneling, Mixing Equipment, Industrial, Oil & Gas, Agriculture, Construction.
