Tough-Coated Hard Powders (TCHP)

Allomet designs & produces nano-engineered Tough-Coated Hard Powders (TCHP) consisting of extremely hard core particles encapsulated in a very tough protective shell, utilizing globally-patented particle coating technology. This unique technology creates an entirely new class of micro-structure materials. Whether pressed and sintered into a solid shape or applied as a surface coating, TCHP provides exceptional wear-resistance performance beyond other superhard, ceramic, or carbide materials.

HNT Superhards

Diamond & cBN Based Powders

TCHP Superhard Materials are made of high quality diamond, cBN "core" particles and coated with either nanolayers of tungsten carbide or titanium carbonitride—and an optional cobalt or nickel binder. These materials offer many of the conventional properties of superhards, with the addition of fracture toughness. The precise design of these materials allow for mechanical, chemical, and thermal properties to be customized to match demanding, high-value application needs.

Diamond is hardest material known to man but it does have one inherent flaw. Standard diamond materials are suseptible to fracture to to their low fracture toughness. Diamond TCHP has overcome this hurdle by individually coating each diamond particle with layers of tungsten carbide and cobalt/nickel. When consolidated, this coating creates a high toughness matrix that provides both extreme wear resistance and toughness.


Available sizes and configurations:

​

  • Fine (3-6 micron)

  • Standard (8-16 micron)

  • Available with Tungsten Carbide, Ti(C,N), Co and/or Nickel coating

With about half the hardness of diamond, cBN is the second hardest material known to man but it shares the same property flaw as diamond (low toughness). cBN TCHP overcomes this flaw by individually coating each cBN particle with layers of tungsten carbide and a very thin layer of cobalt or nickel, forming a protective shell. When consolidated, this shell allows for the formation of a high toughness matrix, providing both extreme wear resistance and toughness.


Available sizes and configurations:

​

  • Fine (3-6 micron)

  • Standard (8-16 micron)

  • Available with Tungsten Carbide, Ti(C,N), Co and/or Nickel coating

HNT Ceramics

Ti(C,N) Alumina & SiC Based Powders

TCHP Ceramic materials are comprised of high quality ceramic "core" particles which are coated with nanolayers of tungsten carbide and a cobalt or nickel binder layer.  When consolidated, these materials create a matrix of uniformly dispersed hard "core" particles spread throughout a tough WC-Co or WC-Ni matrix.  The result is an unsurpassed combination of combined hardness and toughness which provides significantly increased wear resistance over conventional cemented carbide materials.

Alumina TCHP offers extreme wear resistance as well as high hardness at elevated working temperatures which makes it ideal for surface coatings and temperature sensitive applications.


Available sizes and configurations:

​

  • Fine (2 micron)

  • Standard (5 micron)

  • Available with tungsten carbide and cobalt or nickel binder

Available sizes and configurations:

​

 

  • Coarse (40-60 micron)

  • Standard (8-16 micron)

  • Available with Tungsten Carbide, Ti(C,N), Co and/or Nickel coating
