Shot peen surface roughness
SpletThe effects of shot peening on the corrosion and wear resistance of 2205 duplex stainless steel were studied. The results indicated that there were mainly two factors caused by shot peening that affected the corrosion and wear resistance of the steel: structural refinement and roughness. Structural refinement provides diffusion channels to form a passive film … SpletShot peening is a cold working process in which the surface of a component is peened with small spherical balls called shots. The process induces plastic deformation on the surface, relieves surface tensile stresses and introduces beneficial compressive residual stresses.

SpletShot peening treatment was conducted to the surface of HQ 805 material by using steel ball with 0.6 mm diameter and 40-50 HRC roughness. It was conducted with 7 bar compressor pressure, 100 mm shot distance from the nozzle to the sample surface in 10, 20 and 30 minutes shot duration. The effects of shot peening duration were investigated. SpletIf the ball diameter is increased, the component surface roughness will become greater and there are certain machine operating restrictions. A ball size of 0.05 to 1 mm diameter is commonly used. ... surface of the parts to be shot peened. The sample parts are shot peened until the necessary intensity and coverage is achieved. Another
