Regardez Jim Shipley expliquer comment la fabrication additive (AM) et le pressage isostatique \u00e0 chaud (HIP) permettent de produire des \u00e9changeurs de chaleur l\u00e9gers et performants pour l’a\u00e9rospatiale, d’une durabilit\u00e9 et d’une efficacit\u00e9 sup\u00e9rieures.<\/p>\n
Gr\u00e2ce \u00e0 la fusion sur lit de poudre (PBF), les fabricants peuvent cr\u00e9er des structures complexes et l\u00e9g\u00e8res avec des surfaces \u00e9lev\u00e9es pour am\u00e9liorer le transfert de chaleur, ce qui permet d’\u00e9conomiser du carburant ou d’augmenter la capacit\u00e9 de la charge utile. Toutefois, les composants AM \u00e0 parois minces sont souvent confront\u00e9s \u00e0 des probl\u00e8mes tels que la porosit\u00e9, les fissures, la poudre pi\u00e9g\u00e9e et la distorsion, qui peuvent avoir un impact sur les performances. <\/p>\n
D\u00e9couvrez comment le HIP et le traitement thermique \u00e0 haute pression (HPHT\u2122) rel\u00e8vent ces d\u00e9fis en \u00e9liminant les d\u00e9fauts, en augmentant la dur\u00e9e de vie en fatigue, en am\u00e9liorant les propri\u00e9t\u00e9s m\u00e9caniques et en garantissant des tol\u00e9rances dimensionnelles sup\u00e9rieures.<\/p>\n
Enfin, voyez comment le traitement de surface post-HIP am\u00e9liore encore la r\u00e9sistance \u00e0 la fatigue et la robustesse globale, faisant de PBF + HIP + traitements de surface une solution puissante et industrialis\u00e9e pour la fabrication d’\u00e9changeurs de chaleur durables et \u00e0 haut rendement pour l’a\u00e9rospatiale.<\/p>\n","protected":false},"featured_media":34958,"menu_order":0,"template":"","knowledge-center_materials":[547,529,517,523,553],"knowledge-center_processes":[363,580],"knowledge-center_language":[135],"knowledge-center_type":[586],"knowledge-center_industry":[347,350,244],"knowledge-center_topic":[235],"class_list":["post-38536","knowledge-center","type-knowledge-center","status-publish","has-post-thumbnail","hentry","knowledge-center_materials-aluminium-alloy-fr","knowledge-center_materials-intermetallics-fr","knowledge-center_materials-stainless-steel-fr","knowledge-center_materials-super-alloy-fr","knowledge-center_materials-titanium-alloy-fr","knowledge-center_processes-fabrication-additive","knowledge-center_processes-hip-et-traitement-thermique","knowledge-center_language-english","knowledge-center_type-webinaire","knowledge-center_industry-aeronautique","knowledge-center_industry-defense","knowledge-center_industry-space-fr","knowledge-center_topic-material-densification-fr"],"acf":[],"_links":{"self":[{"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/knowledge-center\/38536","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/knowledge-center"}],"about":[{"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/types\/knowledge-center"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/media\/34958"}],"wp:attachment":[{"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/media?parent=38536"}],"wp:term":[{"taxonomy":"knowledge-center_materials","embeddable":true,"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/knowledge-center_materials?post=38536"},{"taxonomy":"knowledge-center_processes","embeddable":true,"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/knowledge-center_processes?post=38536"},{"taxonomy":"knowledge-center_language","embeddable":true,"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/knowledge-center_language?post=38536"},{"taxonomy":"knowledge-center_type","embeddable":true,"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/knowledge-center_type?post=38536"},{"taxonomy":"knowledge-center_industry","embeddable":true,"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/knowledge-center_industry?post=38536"},{"taxonomy":"knowledge-center_topic","embeddable":true,"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/knowledge-center_topic?post=38536"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
