Abstract Scope |
Inconel 625 is a nickel-based superalloy with excellent mechanical properties and corrosion resistance at high temperatures used in harsh environments as joints, seals, valves, etc; which are subjected to fretting loads. This study evaluates the fretting wear properties of AM Inconel 625 with its wrought (WR) counterpart at high temperatures up to 700οC. The samples were manufactured by metal powder bed fusion technology using different process parameters. AM samples showed better friction and wear properties at high temperatures than WR samples whereas WR samples fared slightly better at room temperature. In addition, samples are treated using shot peening (SP), and laser peening (LP). SP and LP samples show improved tribological properties at room temperature whereas, at higher temperatures, no improvement was observed. Surface oxide composition and microstructure characterization was done to understand changes in deformation mechanisms affecting friction and wear for AM and WR samples with SP and LP processes. |
