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...

Abstract This study investigated the stress relaxation and fatigue life strength of laser-peened single-crystal nickel superalloy specimens compared to unpeened shot-peened following hot corrosion exposure then testing. The were treated by conventional laser peening a new cyclic plus thermal microstructure engineering process. latter treatment supports benefit unique process involving applicati...

The FeCoNiCrMo0.2 high entropy alloy coatings were deposited on BS960 strength steel by plasma spraying method with four different current intensities (250 A, 350 450 550 A). These then subjected to a subsequent micro-shot peening treatment. Surface characteristics including surface morphology, microhardness and phase composition characterized, the wear resistance of was assessed reciprocal fri...
