...Chunhua Hu; Quanqiang Guo; Xinghao Ji; Yu Liu MoSi 2 coatings were prepared on a 45CrNi substrate by supersonic plasma spraying (SAPS). The tribocorrosion resistance of MoSi 2 coating and posttreated MoSi 2 coating (P-MoSi 2 ) in the seawater environment was analyzed. After posttreatment, some new...

...Alessandro M. Ralls; Jacob Frizell; Pradeep L. Menezes In this work, laser shock peening (LSP) was utilized as a surface-processing technique to modify the tribocorrosion characteristics of cold-spray (CS) 316L SS. Results indicate that with the influence of LSP, the degree of wear–corrosion...

... by abrasion, delamination, and oxidation. In particular, the wear-rate of Cu-based BMG is about 22 times lower than that of conventional NAB when sliding in the air under a load of 5 N. When sliding in 3.5 wt% NaCl solution, Cu-based BMG demonstrates better static-corrosion resistance but worse tribocorrosion...

...Ali Ghanbarzadeh; Farnaz Motamen Salehi; Michael Bryant; Anne Neville A corrosive wear model is considered at the asperity-scale of a tribocorrosive wear system as well as the traditional Archard-type mechanical wear model. The geometry of the surface asperities is modified in a contact mechanics...
