Abstract Laser cladding technology has emerged as an effective method for enhancing the performance of papermaking refiner blades. This study investigates the fabrication of a WC particle-reinforced Ni-based ceramic composite coating on a 65Mn steel substrate using laser cladding. The mechanical properties, wear resistance, and corrosion resistance of the coating are examined, revealing that laser […]<\/p>\n","protected":false},"author":1,"featured_media":4283,"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-4284","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\/vi\/wp-json\/wp\/v2\/posts\/4284","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=4284"}],"version-history":[{"count":3,"href":"https:\/\/www.greenstone-tech.com\/vi\/wp-json\/wp\/v2\/posts\/4284\/revisions"}],"predecessor-version":[{"id":5157,"href":"https:\/\/www.greenstone-tech.com\/vi\/wp-json\/wp\/v2\/posts\/4284\/revisions\/5157"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/vi\/wp-json\/wp\/v2\/media\/4283"}],"wp:attachment":[{"href":"https:\/\/www.greenstone-tech.com\/vi\/wp-json\/wp\/v2\/media?parent=4284"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/vi\/wp-json\/wp\/v2\/categories?post=4284"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/vi\/wp-json\/wp\/v2\/tags?post=4284"},{"taxonomy":"table_tags","embeddable":true,"href":"https:\/\/www.greenstone-tech.com\/vi\/wp-json\/wp\/v2\/table_tags?post=4284"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
