Effect of shot peening coverage on residual stress and surface roughness of 18CrNiMo7-6 steel

TL;DR: In this article, the residual stress and surface topography obtained by various shot peening treatments were experimentally and theoretically examined, and it was found that the ratio between the layer thickness of compressive stress and the critical depth of maximum stress generally lies in the regime of 3.6-4.3 after shot-peening.

Effect of shot peening coverage on hardness, residual stress and surface morphology of carburized rollers

TL;DR: In this article, the effect of shot peening coverage on residual stress, surface roughness, microhardness and microstructure of rollers is investigated, and it is shown that the shot-peening leads to a slight increase of surface and near-surface hardness from 690 HV to 740 HV, and an appreciably increasing of the subsurface maximum compressive residual stress.

Investigation on the effect of shot peening coverage on the surface integrity

TL;DR: In this article, a multiple-shot model was used to estimate the evolution of shot peening coverage and the influences of coverage on residual stress, plastic strain and surface topography, and the predicted results reveal that as the shot-peening coverage increases from 100% to 400% under the given processing condition, the maximum residual stress and plastic strain will increase gradually.

Effects of different shot peening parameters on residual stress, surface roughness and cell size

TL;DR: In this article, a random multi-shot model which incorporated dislocation density-based constitutive equations was established, and the effects of peening velocity, peening coverage and double peening on the surface integrity in terms of the residual stress, surface roughness and dislocation cell size were analyzed.

Effect of surface properties on high cycle fatigue behaviour of shot peened ductile steel

TL;DR: In this paper, a phenomenological approach is proposed to characterise and to correlate qualitatively and quantitatively the influence of local shot peened surface properties on fatigue limit of treated specimens.

Effect of shot peening on surface fatigue life of carburized and hardened AISI 9310 spur gears

TL;DR: In this article, surface fatigue tests were conducted on two groups of AISI 9310 spur gears with standard ground tooth surfaces, with the second group subjected to an additional shot peening process on the gear tooth flanks.

Pitting of Gears and Discs

TL;DR: Pitting tests using 127 mm (5 in) centres distance gear rig under controlled conditions are described in this paper, which confirm Dawson's conclusion that an important factor influencing pitting life is the ratio of surface roughness to the calculated lubricant film thickness.

Bending Strength of Carburized SCM420H Spur Gear Teeth

TL;DR: In this article, the residual stress at the root surface, the surface hardness and the core hardness on the fatigue limit were quantitatively determined from the results of fatigue test and a formula was finally proposed as a function of these factors.
Journal ArticleDOI

The Effect of Shot Peening on the Bending Strength of Carburized Gear Teeth

TL;DR: In this article, the effects of shot peening on the bending strength of carburized spur gears of m = 5 were investigated and the residual stress of every test tooth was measured by an X-ray diffraction method.
