              1. Technology Overview Laser cladding technology is an advanced surface engineering technique that uses a high-energy laser beam to simultaneously melt both the coating material (powder or wire) and a thin layer of the substrate. The rapid solidification process forms a metallurgical bond between the coating and the substrate. The coatings created by this method […]<\/p>\n","protected":false},"author":1,"featured_media":4621,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[5,3],"tags":[102],"table_tags":[],"class_list":["post-4622","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-professional-knowledge","category-blog","tag-sheldon-li"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/posts\/4622","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=4622"}],"version-history":[{"count":3,"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/posts\/4622\/revisions"}],"predecessor-version":[{"id":5184,"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/posts\/4622\/revisions\/5184"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/media\/4621"}],"wp:attachment":[{"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/media?parent=4622"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/categories?post=4622"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/tags?post=4622"},{"taxonomy":"table_tags","embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/table_tags?post=4622"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
