Aircraft engine blades operate under extreme conditions of high temperature, high pressure, and high rotational speed. As core components of the engine, they are vulnerable to fatigue cracks, corrosion, wear, erosion, impact damage, and tip abrasion throughout long service cycles. If not identified and repaired in time, these defects may severely reduce aerodynamic efficiency and […]<\/p>\n","protected":false},"author":1,"featured_media":5681,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[6,3],"tags":[103],"table_tags":[],"class_list":["post-5682","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-application-cases","category-blog","tag-lydia-liu"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/posts\/5682","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=5682"}],"version-history":[{"count":1,"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/posts\/5682\/revisions"}],"predecessor-version":[{"id":5683,"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/posts\/5682\/revisions\/5683"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/media\/5681"}],"wp:attachment":[{"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/media?parent=5682"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/categories?post=5682"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/tags?post=5682"},{"taxonomy":"table_tags","embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/table_tags?post=5682"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
