Laser cladding\u00a0technology is an interdisciplinary advanced surface modification technique that involves the use of a laser beam to rapidly heat and melt alloy or ceramic powders on the surface of a substrate. After the laser beam is moved away, the material self-cools, forming a low-dilution metallurgically bonded surface layer. This process significantly improves the substrate\u2019s […]<\/p>\n","protected":false},"author":1,"featured_media":5007,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[4,3],"tags":[103],"table_tags":[],"class_list":["post-5006","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news-release","category-blog","tag-lydia-liu"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/posts\/5006","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=5006"}],"version-history":[{"count":2,"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/posts\/5006\/revisions"}],"predecessor-version":[{"id":5069,"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/posts\/5006\/revisions\/5069"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/media\/5007"}],"wp:attachment":[{"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/media?parent=5006"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/categories?post=5006"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/tags?post=5006"},{"taxonomy":"table_tags","embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/cs\/wp-json\/wp\/v2\/table_tags?post=5006"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
