Hot Isostatic Pressing Core technologies Thermal Processing Heat Treatments Metal Joining Hot Isostatic Pressing Surface Technology

Heat treatments Used to alter microstructure of materials to impart specific properties Extensive range of controlled processes Used by virtually every market sector Bodycote is the world’s largest heat treater

Metal joining Specialist processes Vacuum brazing – Complex Engineering Electron beam welding (EBW) uses only parent metal Bodycote has the largest EBW capacity in Europe

Hot isostatic pressing Advanced materials technology Combines very high temperature and pressure Used to eliminate porosity in castings Used to join by diffusion bonding Enables manufacture of complex shapes via powder metallurgy Bodycote has, by far, the largest HIP capacity in the world

Surface technology Thermally sprayed and thermally formed coatings are used to prolong component life Protection from environmental factors such as corrosion, abrasion and temperature Includes specialised ceramic and metal powder coatings Focus on high added value applications for aerospace, power generation and oil & gas sectors

Brazing for the CLIC Capabilities

A large capability in brazing From mass production parts brazed in continuous furnace To single and complex parts brazed in vacuum furnace

Brazing for the CLIC Know-how and brazed assemblies

1st step: Development of vacuum brazing and diffusion bonding of copper disks

Vacuum brazing in several cycles Multi – step brazing

Vacuum brazing of parts with complex shapes

Super-accelerating structures assemblied by brazing and EBW Cooling circuit Vacuum flange RF flange Manifold Interconnection flange RF waveguide Accelerating structure Super-accelerating structure Target sphere

Accelerating structure A lot of parts brazed step by step

Super-accelerating structures The first brazed meter

The begining of the great adventure for the Cern

Conclusion Heat treatment, Metal joining, HIP and Surface Technology are a vital link of CLIC components manufacturing.
