A system for cooling and holding a testpiece in an effective manner while the testpiece is subjected locally to high heat flux. The testpiece includes an inside face extended by parallel strips that leave between them channels for passing a cooling fluid, and parallel fins of an intermediate part are inserted between the strips.

Device evaluating thermomechanical fatigue of a material

The invention relates to a method of depositing a coating on a part having its surface made of silicon carbide. The method comprises the following steps: The invention also provides a device for measuring deformation, which device comprises a first alumina coating obtained by atmospheric thermal spraying onto the silicon carbide layer covering the substrate of the part after it has been treated by superposing laser impacts, a free filament strain gauge placed on the coating, and an additional alumina coating obtained by atmospheric thermal spraying onto the strain gauge.

Method of making a deposit on an SiC-covered substrate

A method of making a device for measuring deformation includes a step of depositing a silicon adhesion underlayer on a silicon carbide surface by chemical vapor spraying, and a step of depositing a coating on the silicon adhesion underlayer by atmospheric thermal spraying.

Method of making a device for measuring deformation

A powder material for forming an abradable coating, the material comprising a metal powder based for the most part on aluminum and containing manganese or calcium. The material is applicable to seals of a turbomachine.

Powder material for an abradable seal

The invention concerns a method which consists in maintaining the two ends ( ) of the bar ( ) on the end supports ( ) of a frame ( ), one of the ends ( ) being maintained fixed, and in driving the bar in rotation. The invention is characterised in that it consists further in drawing the bar ( ) while spraying a coat on the bar, the drawing of the bar corresponding to an elongation of about 0.2 to 0.001%.

Device for producing a coating rod for use in the paper industry

The invention concerns a non-stick coating ( ) for cooking utensils ( ) characterized in that it is selected among the group comprising (a) ceramics alone selected among titanium oxynitride, titanium suboxides, titanium subnitrides, spinels, mixed spinels; and (b) ceramo-metallic mixtures wherein the ceramics are selected among titanium oxynitrides, titanium suboxides, titanium subnitrides, spinels, cerium fluoride, silicon carbide, pyrolitic carbon, boron carbide, and the metal is titanium.
