Title (EN) COMPOSITE MATERIAL WITH TWO OR A PLURALITY OF LAYERS
(FR) MATERIAU COMPOSITE A DEUX OU PLUSIEURS COUCHES
Abstract: front page image
(EN)Composite material with two or a plurality of layers with a coating layer (5) which is applied directly on the rough surface (2) of a substrate and which comprises a lake base of polyimid and at least one finely spread additive in said base. Upon forming the coating layer (5) as a friction or sliding layer, such layer may contain about 99 to 60% by volume, preferably 90 to 80% by volume of thermo-setting polyimid lake and about 1 to 40% by volume, preferably 10 to 20% by volume of self-lubrication additives, particularly low molecular weight PTFE, with a grain size comprised between 5 and 7 (Alpha). For manufacturing said composite material, the powder additive is intimately mixed with the polyimid lake and homogenized until it becomes slightly viscous or pasty, deposited on the metal substrate and fixed thereto by sintering.
(FR)Materiau composite a deux ou plusieurs couches avec une couche de recouvrement (5) qui est appliquee directement sur la surface rugueuse (2) d"un substrat et qui comporte une base de laque de polyimide et au moins un additif finement disperse dans cette base. Lors de la constitution de la couche de recouvrement (5) en couche de frottement ou de glissement, celle-ci peut contenir a peu pres de 99 a 60% en volume, de preference de 90 a 80% en volume de laque de polyimide thermo-durcissable et a peu pres de 1 a 40% en volume, de preference de 10 a 20% en volume d"additifs auto-lubrifiants (4), en particulier du PTFE a faible poids moleculaire, de dimension granulaire situee entre 5 et 7 (Alpha). Pour la fabrication du materiau composite, l"additif en poudre est intimement melange a la laque de polyimide puis homogeneise jusqu"a l"etat faiblement visqueux ou pateux, depose sur le substrat metallique et fixe a celui-ci par frittage.
