Aircraft engine blades operate in extreme environments, facing high temperatures, centrifugal forces, corrosion, vibration, and complex stress conditions. Because blade replacement is extremely costly, developing reliable blade repair and remanufacturing technologies has become a crucial industrial priority. Among all repair technologies, laser cladding\u00a0has emerged as one of the most effective, offering precise material deposition, minimal […]<\/p>\n","protected":false},"author":1,"featured_media":5664,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[6,3],"tags":[102],"table_tags":[],"class_list":["post-5666","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-application-cases","category-blog","tag-sheldon-li"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/posts\/5666","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/comments?post=5666"}],"version-history":[{"count":2,"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/posts\/5666\/revisions"}],"predecessor-version":[{"id":5669,"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/posts\/5666\/revisions\/5669"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/media\/5664"}],"wp:attachment":[{"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/media?parent=5666"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/categories?post=5666"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/tags?post=5666"},{"taxonomy":"table_tags","embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/table_tags?post=5666"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
