The coating comprises <i>γ</i>-Ni, M<sub>23</sub>C<sub>6</sub>, MoNi, MoNi<sub>4</sub>, Ni<sub>3</sub>B, WC and W<sub>2</sub>C. The interface layer removes pores and inclusions in the substrate, thereby creating a strong metallurgical bond and fortified coating-substrate adhesion.

Moreover, tungsten carbide (WC) nanoparticles refine the grain structure, strengthen grain boundaries, limit dislocation slip and improve impact resistance. The toughened layer absorbs energy via plastic deformation, further augmenting impact resistance. As a result, the composite coating exhibits better impact toughness than high-frequency quenched specimens. Impact tests and finite element analysis demonstrate that the composite coating’s maximum compressive stress is 253.11 MPa, compared to 288.63 MPa for the high-frequency quenched layer. Due to its high hardness and brittleness, the high-frequency quenched layer endures restricted plastic deformation under the impact, developing stress concentration zones that lead to cracks and fracture and lowered impact resistance. Alternatively, the <i>γ</i>-Ni solid solution in the composite coating provides good toughness, allowing more plastic deformation, decreased stress, alleviated stress concentration and significantly improved impact resistance.</p></div>","PeriodicalId":679,"journal":{"name":"Journal of Thermal Spray Technology","volume":"34 5","pages":"1873 - 1892"},"PeriodicalIF":3.3,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145142394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
