Abstract Scope |
Acting as a novel technology, the application of high pressure deposited (HPD) coatings has attracted to attention of many due to its solid-state deposition-like features. From an industrial perspective, the application of HPD coatings is fundamental to preserving the working lifespans of various machining components. This is especially true in chloride-rich environments that are continuously exposed to oscillatory contacting tangential movements. However, due to the porous nature of HPD coatings, they suffer from rapid material degradation due to severe pitting and premature brittle fracture. In this work, we investigated the influence of FSP on the fretting-corrosion mechanisms of HPD steel. It was found that the effect of FSP enhanced the metallurgical bonding and intrinsic hardness of the HPD coating. As such, their fretting-corrosion performance was also improved, concluding that FSP is a viable method to enhance the surface quality of HPD coatings. |
