<p>A screw-threaded element, a gear or a cylinder of a piston and cylinder device is produced by diffusion bonding (typically by hot isostatic pressing) a cladding material to a suitably shaped body. The cladding material is shaped before, during or after the diffusion bonding step to define (a) screw threading in the case of a screw or a nut, (b) gear teeth in the case of a gear, or (c) an internal cylinder wall having good piston seal characteristics in the case of a cylinder of a piston and cylinder device.</p> |
