Abstract

The manufacture of solid and hollow diamond fibres and of fibre arrays is described. The effective diamond deposition rate, when defined as mass per unit volume rather than in µm.h^-1, can be substantially greater for fibre arrays and this could lead to lower cost CVD diamond. Monofilament diamond fibres have been coated with a metallic matrix by physical vapour deposition and consolidated by hot pressing to produce metal matrix composites. Examples of diamond fibres embedded in a Ti-alloy matrix are presented.
