Corrigendum to “Research on the mechanism of DD6 single crystal superalloy wear resistance improvement by femtosecond laser modification” [Appl. Surf. Sci. 577 (2022) 151691] (Applied Surface Science (2022) 577, (S0169433221027355), (10.1016/j.apsusc.2021.151691))

The authors regret the writing mistakes. In “Section 3.2, Page 4”, “Fig. 7(d–f)” should be “Fig. 7”, “Besides, the slip dislocation occurs in the γ phase” should be “Besides, the slip dislocation occurs in the γ’ phase”. In “Section 4, Page 5”, “multiple dislocation tangles occur in γ phase and γ’/γ’ interface” should be “multiple dislocation tangles occur in γ phase and γ/γ’ interface”. In Figs. 11 and 12, the units of height and wear rate are wrong. So, we hope Figs. 11 and 12 in the article can be replaced by the following Figs. 11 and 12. Correspondingly, in “Section 3.3, Page 5”, “The wear rate of the sample decreases from 7.07 × 10⁻³ mm³/Nm to 3.69 × 10⁻³ mm³/Nm, 5.51 × 10⁻³ mm³/Nm and 4.33 × 10⁻³ mm³/Nm” should be “The wear rate of the sample decreases from 7.07 × 10³ μm³/Nm to 3.69 × 10³ μm³/Nm, 5.51 × 10³ μm³/Nm and 4.33 × 10³ μm³/Nm”. In addition, the postcode of affiliation b should be 710038 updated as above. These corrections do not affect the conclusion of this work.
