The invention relates to a flexible electrode () made of a metal base material () with a coating () made of polycrystalline doped electrically conductive diamond and an intermediate layer () between the base material () and the coating (), wherein the base material () is in the form of a needle or wire, wherein at least one circumferential, circular or spiral groove () is formed in the base material () about a longitudinal axis () of the base material ().

Flexible electrode made of a metal base material

The invention relates to an implant or medical tool made of a metal or having a surface made of a metal for use in a therapeutic treatment, wherein the implant or the tool has, on its/the surface, a coating with polycrystalline doped electrically conductive diamond, wherein the therapeutic therapy is a treatment of a microbial infection of a human or animal body,

Implant or medical tool made of a metal

The cutting plateincludes a base bodymade of a sintered hard metal. On a top sideof the base bodythere are one or multiple intermediate layersthat include an adhesion-promoting layer. The adhesion-promoting layeris made of a boron-containing nitride of a transition metal of group IV, group V, and group VI, and contains a plurality of small platesoriented at an angle relative to the top side. A diamond layer that is grown on the adhesion-promoting layerincludes stalk-shaped crystals, oriented vertically relative to the top side, having an aspect ratio greater than three.

Cutting plate and manufacturing method

The invention relates to a device for coating a substrate using CVD, in particular for coating with diamond or silicon, wherein a neat conductor array composed of a plurality of elongated heat conductors () is provided in a housing (), said heat conductors extending between a first () and a second electrode (), wherein the heat conductors are held individually tensioned by a weight () attached to one end thereof. To increase the life of the neat conductors (), the invention proposes that the weight () or the heat conductor () be guided at the second electrode (), forming an electrical loop contact, in such a way that a vector of the weight force (G) produced by the weight () makes an angle (&#x3b1;) of no more than 45&#xb0; with a direction of the longitudinal extension of the heat conductor ().

Device and method for coating a substrate using CVD

The invention relates to a device for coating a substrate () using CVD, in particular for coating with diamond or silicon, wherein a heat conductor array comprising a plurality of elongated heat conductors () is provided in a housing (), said heat conductors extending between a first () and a second electrode (), wherein the heat conductors () are held individually tensioned by a tensioning device attached to one end thereof. For the purposes of improving the life of the heat conductors (), the invention proposes that the tensioning device comprises a tilt arm () having a tensioning weight (G), the heat conductor () being attached to the first end (E) of said tilt arm, and the second end thereof substantially being mounted pivotably about a horizontal axis (H).
