NiCoCrAlY alloys powders

NiCoCrAlY alloys are thermal spray coating materials that are known for their excellent resistance to oxidation and hot corrosion. Coatings of these materials are used as bond coats for ceramic top coats. The addition of yttrium acts to improve the adhesion of this oxide layer. The presence of cobalt in NiCoCrAlY alloys improves coating ductility and hot corrosion resistance.

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.
