Title (EN) CHEMICALLY BONDED COATED METAL-TO-METAL SEALS
(FR) JOINTS MÉTALLIQUES REVÊTUS COLLÉS CHIMIQUEMENT
Abstract:
(EN) Oilfield tools having a metal-to-metal seal formed between a first metal surface and a second metal surface, wherein at least one of the first and second metal surfaces are at least partially coated by chemical bonding or physical deposition of a coating material that is more durable and has a lower coefficient of friction than either or both of the first and/or second metal surfaces to which the coating material is applied.
(FR) L'invention concerne des outils de champ pétrolifère comprenant un joint métallique formé entre une première surface métallique et une seconde surface métallique, la première et/ou la seconde surface métallique étant au moins partiellement revêtue(s) par collage chimique ou dépôt physique d'un matériau de revêtement qui est plus durable et possède un coefficient de frottement inférieur à celui de l'une ou l'autre des première et seconde surfaces, ou des deux, sur lesquelles le matériau de revêtement est appliqué.
