Hardfacing strengthens foundry equipment
A special tungsten-carbide powder provides exceptional anti-abrasion characteristics for frequently used wearing parts involved with sand regeneration and producing casting molds.
To prepare sand molds for foundry of cast iron or steel, the sand must be mixed with an organic binder such as soot or clay, which subjects mixer blades to significant wear Without hardfacing, a mixer blade is only functional for only a month and a half during this standard process

Tungsten-carbide gives high abrasion resistance
Manufacturer of hardfacing products, has developed a special tungsten-carbide powder, which, when deposited on the tool's surface, provides exceptional abrasive resistance for various uses.
Hardfacing systems protect against abrasion
Optimized hardfacing systems protect diameters subjected to heavy stress and thrust surfaces with high-yield strength to mmet the needs of bricks and tile production in the ceramics industry.
Technogenia, a manufacturer of hardfacing products, has developed a special tungsten-carbide powder known as Spherotene that, when deposited on a blade's surface, provides exceptional anti-abrasion characteristics that are perfectly suited for frequently used wearing parts involved with sand regeneration and producing casting molds for the foundry industry.
The incredibly strong carbide particles are applicable by a welded-on cast-nickel cord, thermal spray, special castings, or precision laser, providing almost ten times a longer service life than with a more traditional chrome-carbide hardfacing.
Technogenia's hardfacing cords Technodur and Technosphere provide anti-abrasion protection with an exceptional performance and exhibit an excellent resistance to accidental shock.

US company said it is the first to to use the latest diode laser technology - 4kW - with an NC machine to deposit anti-abrasive coatings on parts up to 12m long.
Technique simplifies production leak testing
Leak test technique simplifies and increases production leak test repeatability and selects the ideal fill and stabilization times based on the volume and temperature of the product.
Tungsten-carbide hardfacing forms a metallurgical bond with the base metal on the part to protect against wear and impact.
The Spherotene powders consist of spherical particles of monocrystaline tungsten carbide that are extremely hard, between 1800 and 4000 HV (Vickers Hardness).
The applicable cords, Technosphere and Technodur, are reels of flexible, nickel-core wire coated with Spherotene and provide unequalled performance for all types of scrapers, feeder heads, cutter blades, corner pieces, mold drills, etc These two types differ in carbide hardness and are available in diameters ranging from 0.1 to 0.5in to be welded to parts with an oxy torch for achieving the desired degree of anti-abrasion and impact protection.
The spherotene-based coatings provide outstanding protection for many wear parts used in sand regeneration and in preparing molds in foundry works.
The compactness and the anti-abrasion and anti-erosion features of the cords provide unequalled performance for all types of scrapers, feeder heads, cutter blades, corner pieces, mold drills, etc The company's Technocasting process is also well suited for the foundry industry as it produces hard-facing for complex, angular shapes for mold drills.
These solutions are currently used by all large foundries for the automobile industry in Europe.
