Product Description

Carbide powder has great erosion, sliding and fretting wear resistance for applications under 1000°F because its high hardness. It is good selection for wear resistant thermal spray coating application.

It can be used for aircraft flap tracks, expansion joints compressor stators, compressor air seals impeller, shafts exhaust fans agricultural cutting, parts pump housings etc.

Truer carbide powders include pure WC, WC-Co, WC-Ni, WC-Co-Cr, WC-Co-CrNi, WC-Ni-Cr, WC-CrC-Ni, WC-WB-Co, WC-Ni60(NiCrBSi), WC-Ni50, WC-Ni-Ni60, WC-Co-Ni60, Cr3C2-10NiCr, Cr3C2-WC-NiCr, TiC, SiC, AlN, WC-TiC-TaC etc.

 

Carbide powders can be produced by sintering & crushing or agglomeration sintering process, respectively for non-spherical or spherical shape powders.

 

When choosing a carbide powder, the particle size & shape and type of carbide selected are important in determining the correct material to combat various forms of erosion, abrasion and wear. Whereas the amount of metal matrix in the coating (nickel, cobalt, or alloy) will depend on the toughness and abrasion resistance required.

Below is Catalogue of common carbide powders of Truer.

Applications

How we play a role in the industry

HIP Technology

Hot Isostatic Pressing (HIP) technology works by placing the product in a closed container, filling it with inert gas and sintering or densifying the product at a very high temperature (usually close to the forging temperature of the material) and at a very high pressure (usually 100 – 140 MPa). This allows the product to be sintered or densified.

MIM Technology

MIM products can be complex in shape, precise in size, high in strength and produced automatically in large quantities, and can significantly reduce the complexity and cost of traditional metalworking

SLM Technology

SLM, also known as Selective Laser Melting, is similar in principle to SLS in that a laser is used to melt and solidify metal powder in a specified area, which is then moulded in a layer-by-layer stack.

EBM Technology

Electron beam melting refers to a vacuum melting method in which the kinetic energy of a high speed electron beam stream is converted to heat as a heat source for melting metals under high vacuum. The abbreviation is EBM.
