A Cr3C2-Al2O3-NiCr composite coating was prepared on an INCONEL600 alloy surface through high-velocity oxygen-fuel spraying followed by further processing high-energy shot peening to create the coating. The microhardness and friction properties of are analyzed a tester reciprocating tester. microscopic structure wear trace were scanning electron microscope (SEM). element distribution energy-dis...

The near-surface properties of maraging steels are key to controlling their mechanical properties. They can be tailored by surface treatments such as shot peening and also influenced prior machining. This study aims at determining the respective roles grinding processes on microstructure Custom 465 stainless steel. A combination experimental techniques, including X-ray diffraction (XRD), transm...

A theoretical study of the stress-strain state helical cylindrical compression springs used in suspension vehicles during shot peening is carried out. The front spring studied by mechanical-mathematical methods and deformation theory plasticity, particular, method small elastic-plastic deformations. It established that reduces pre-stressing 2.54% due to an increase torque cross section coil 4.3...

Aero engine compressor disks are typically life-limited parts and it is necessary to secure them through the implementation of an engineering plan a manufacturing plan. Specifically, recommends quantification safety on basis probabilistic risk assessment (PRA). However, direct correlation between plans limited, effect parameters remains be investigated. Shot peening, as typical method surface m...
