Use the HIP process for cladding and joining parts - expect stronger bonding, improved density of sprayed coatings and welds, plus reductions in net component costs



 
 
 
In today’s market, re-casting components is not financially viable. HIP’ing may be used to recover castings with microporosity and voids.

 
 
 
HIP achieves zero porosity in PM parts and leads to enhanced mechanical properties, cost reductions and enhanced design possibilities.

 
 
 
Powder Metallurgy

Billets and Near Net Shape parts:
High purity and homogeneous billets or near net shape parts with 100% density are produced by HIPing encapsualted metal powders. Typically a container is manufactured (mild or stainless steel), filled with the powder, sealed, evacuated and HIPed. The process takes place well below the melting point of the material and results in a very fine grained molecular solid structure. HIPed PM parts represent a significant saving in lead time and material/machining costs when compared with parts machined from solid billets. Parts and billets with difficult material composition can be achieved using the PM approach.

Metal Matrix:
The wear resistance/part life can be improved by mixing the steel powders with hard particles like diamonds, carbides, nitrides, oxides, borides or silicides. Low density, high stiffness, light alloy based materials with ceramic fibre particles can also be produced. The process allows freedom in chemical composition, particle size, particle distribution and form. Solid/solid, powder/solid or powder/powder composite products can easily be produced with perfect bonds between the particles and the material that surrounds them. Theoretical (100%) density is achievable along with uniform particle distribution, strength and low grain growth.

Ceramics and Glass:
The combination of pre-sintering or glass encapsulation and HIPing offers the possibility of producing high quality ceramic components. Hot Isostatic Pressing significantly improves the long term strength retention of refractory materials at sustained high temperatures.
