A process and apparatus of producing a product having a wrought structure. The process comprises the step of: applying heat and a compressive load simultaneously to an application area of a cold spray deposition preform to transform the comprising consolidated particle structure into a wrought structure, the compressive load being applied laterally to the application area. The application of compressive load and heat to the application area raises the temperature of the material of the preform in the application area to between the recrystallisation temperature and the melting point of the material.

Process for forming wrought structures using cold spray

The present invention relates to a method of manufacturing a pipe, which method comprises cold-gas dynamic spraying of particles onto a suitable support member thereby producing a pipe, and separating the pipe from the support member.

Manufacture of pipes

A process for producing a titanium load-bearing structure, which comprises cold-gas dynamic spraying of titanium particles on to a suitably shaped support member, and a titanium load bearing structure so-produced.

Process for producing a titanium load-bearing structure

This invention relates to a method of forming sections of seamless titanium or titanium alloy pipe. The method involves providing a substrate for forming pipe and a sleeve of a section of pipe on the substrate. The pipe section has an end from which the substrate projects. The pipe is formed by spraying particles of titanium or titanium alloy generally parallel to a longitudinal axis of the substrate to impact a face of the end and to cause particles to bond to and to accumulate on the pipe end to form pipe. The method further involves moving formed pipe longitudinally relative to the substrate to remove formed pipe from the pipe-forming substrate and continuing to spray titanium or titanium alloy particles onto the end face to cause further pipe to form continuously and integrally with the formed pipe. This enables a seamless titanium or titanium alloy pipe to be formed of any desired length.
