Laser Cladding, also known as laser overlay or laser coating, is an advanced surface modification technology. This technique uses high-energy lasers as a heat source and alloy powders as welding materials. The laser and alloy powders are applied simultaneously to the metal surface, rapidly melting it to form a molten pool, which then quickly solidifies […]<\/p>\n","protected":false},"author":1,"featured_media":4813,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[5,3],"tags":[101],"table_tags":[],"class_list":["post-4837","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-professional-knowledge","category-blog","tag-graham-luo"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.greenstone-tech.com\/vi\/wp-json\/wp\/v2\/posts\/4837","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.greenstone-tech.com\/vi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.greenstone-tech.com\/vi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/vi\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/vi\/wp-json\/wp\/v2\/comments?post=4837"}],"version-history":[{"count":2,"href":"https:\/\/www.greenstone-tech.com\/vi\/wp-json\/wp\/v2\/posts\/4837\/revisions"}],"predecessor-version":[{"id":5278,"href":"https:\/\/www.greenstone-tech.com\/vi\/wp-json\/wp\/v2\/posts\/4837\/revisions\/5278"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/vi\/wp-json\/wp\/v2\/media\/4813"}],"wp:attachment":[{"href":"https:\/\/www.greenstone-tech.com\/vi\/wp-json\/wp\/v2\/media?parent=4837"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/vi\/wp-json\/wp\/v2\/categories?post=4837"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/vi\/wp-json\/wp\/v2\/tags?post=4837"},{"taxonomy":"table_tags","embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/vi\/wp-json\/wp\/v2\/table_tags?post=4837"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
