There is disclosed a method is set forth for producing diamond film, comprising the following steps: providing a graphite substrate having a surface over which diamond film is to be deposited; depositing diamond film over said surface of the substrate; and sawing through the substrate to saw off a layer thereof that includes the deposition surface and the diamond film.

On forme un revêtement de diamant en film mince, relativement lentement, en utilisant une concentration en méthane relativement faible, et ce revêtement est identifié par ses caractéristiques de spectrographie Raman. Le diamant en film mince dont l'épaisseur est de préférence de 5 à 40 microns, fournit une résistance à l'érosion et à la corrosion, dans un environnement corrosif, nettement supérieure à celle des revêtements usuels de diamant en film mince. Le Demandeur considère que ledit revêtement de diamant en film mince présente une résistance chimique améliorée en raison de sa pureté et de sa qualité. A thin film diamond coating is formed relatively slowly using a relatively low methane concentration, and this coating is identified by its Raman spectrographic characteristics. Thin film diamond, the thickness of which is preferably 5 to 40 microns, provides resistance to erosion and corrosion, in a corrosive environment, significantly greater than that of conventional thin film diamond coatings. The Applicant considers that said thin film diamond coating exhibits improved chemical resistance due to its purity and quality.

A system and method for depositing a CVD diamond coating on a non-planar surface of an object is provided. The system includes a deflector having a deflecting surface which resists diamond coating by the diamond forming reagents produced by the system and which is adapted to withstand the relatively high deposition temperatures is provided. The deflector is positioned, substantially axially with an axis of the distribution head of the CVD engine. The deflector is preferably generally wedge-shaped or conical and coupled to a motor which is adapted to rotate the deflector at a relatively high speed. A mandrel may be positioned about or to one side of the deflector. The deflector is oriented with respect to the distribution head and the mandrel such that a jet exiting the distribution head is deflected by the deflector onto a surface of an object positioned on the mandrel. The object surface may be non-planar.

An apparatus for depositing synthetic diamond on a surface of a substrate includes a deposition chamber and a cooling block having a surface in the deposition chamber that is cooled by heat exchange. The substrate is supported from the cooling block so that the bottom surface of the substrate is spaced from the cooling block surface by a gap, and a gas is provided in the deposition chamber and in the gap, the gas comprising at least 30 percent hydrogen gas. A plasma deposition system forms in the chamber a plasma containing hydrogen gas and a hydrocarbon gas for depositing synthetic diamond on the top surface of the substrate.
