HIP Cladding

HIP Cladding

Diffusion bonding of solid to solid or solid to powder metallurgy material, to produce a bi-metallic component with premium material properties on selected surfaces by encapsulation and hot isostatic pressing.


  • Cladding thickness is not limited in comparison to other coatings
  • Ability to join metals/composites that cannot be bonded by conventional techniques
  • Allows a more economical substrate to be utilised for the majority of the part thereby saving material costs
  • Strength of the joint can match that of the substrate
  • Production of bi-metallic components without the need for welding or fastening techniques, reducing the risk of failure during manufacture
  • Improves life and performance compared to components fabricated solely by the substrate alloy
  • Allows manufacture of components with dimensions near to finish form, with limited machining or finishing operations which reduces the number of processing steps and significantly shortens lead time compared to wrought and coated components.

Application & materials:

HIP cladding applications are found in oil and gas exploration, production and processing; power generation; and the marine, nuclear, chemical, heavy truck, tooling for food manufacture, automotive and electronic industries.

Typical products include valves, seals, subsea manifolds, pipe and forging extrusion rolls and dies.

Materials utilised include most metals and alloys such as stainless steels, tool steels, cobalt-based superalloys, Monels, Inconels, and cermets.

Process details:

Cladding allows the coating of selective surfaces by diffusion bonding; cladding a premium material in powder or solid form to a solid substrate to produce a surface with enhanced resistance to wear and/or corrosion via the fabrication technique of encapsulation and HIP.
