High-velocity oxy-fuel (HVOF) and atmospheric plasma spraying (APS) are the most mature deposition techniques; however, this work evaluates cold spray (CS) to deposit a nanosized WC-17Co powder. Due to its principles, CS prevents degradation of the WC grains when exposed to high temperatures during the deposition by HVOF or APS, producing a hard and dense coating with unaltered WC grains. This study evaluates the performance of CS WC-17Co coatings under erosion by solid particles and abrasion by third body testing, as well as sliding wear behavior. For water-flow exposed surfaces, e.g., piping or hydro turbines, measuring the cavitation and water jet erosion is essential, and minimizing the cavitation phenomena has been a challenge for scholars and design teams. This work presents the effect of different water characteristics (surface tension) on the CS WC-17Co coatings performance. It is noted that reducing this liquid property improves the coating life.

The microstructure of the samples was studied using a field emission scanning electron microscope (FESEM), and their mechanical properties, including density, Vickers hardness, and fracture toughness, were characterized. A wear test was conducted to measure the wear of the 3YSZ antagonist. FESEM results showed that the 3YSZ microstructure sintered at 1600°C was homogeneous, densely packed, and had fewer pores. Furthermore, it also displayed higher relative density, Vickers hardness, and fracture toughness. However, the group of 3YSZ sintered at 1600 °C exhibited the highest antagonist wear.

However, Persson’s theory suffers from the fact that initial size of defects is unknown and fatigue life is not entirely due to propagation, so we investigate a different formulation, where a law for initiation of cracks is used for a specimen with initial roughness of engineering interest. We find that results (in particular dependence on amplitude of roughness, and on friction coefficient) are qualitatively similar to the original Persson and coworkers’ theory, but may differ substantially quantitatively. As the assumption of a constant fatigue threshold may be incorrect for short cracks, both fatigue limit and fatigue threshold are made dependent of crack size, using the Murakami formulation as one of the possible alternatives. This makes wear rate be sensitive to the fine scale details of the roughness spectrum, which has an effect on increasing wear rate and small particles emission. The model seems to have qualitative trends in agreement with experiments, but obviously wear is a very complex phenomenon and many factors may be not captured.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"207 ","pages":"Article 110592"},"PeriodicalIF":6.1,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143474343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
