Influence of shot peening and hard chromium electroplating on the fatigue strength of 7050-T7451 aluminum alloy
(Elsevier B.V., 2007-07-01)
Chromium electrodeposition is a technique for the production of functional coatings on engineering components. These coatings are extensively micro-cracked and present high level of hardness, resistance to corrosion and ...
An evaluation of shot peening, residual stress and stress relaxation on the fatigue life of AISI 4340 steel
(Elsevier B.V., 2002-08-01)
Shot peening is a method widely used to improve the fatigue strength of materials. through the creation of a compressive residual stress field (CRSF) in their surface layers. In the present research the gain in fatigue ...
Effect of a Shot Peening Pre Treatment on the Fatigue Behaviour of Hard Chromium on Electroless Nickel Interlayer Coated AISI 4340 Aeronautical Steel
(ABM, ABC, ABPol, 2002-06)
Multiple layer systems of coatings are considered to have larger resistance to crack propagation in comparison to coatings with simple layer. With regard to fatigue, it is possible to improve the resistance of a component ...
Importance of considering a material micro-failure criterion in the numerical modelling of the shot peening process applied to parabolic leaf springs
(LATIN AMER J SOLIDS STRUCTURES, 2010)
Shot peening is a cold-working mechanical process in which a shot stream is propelled against a component surface. Its purpose is to introduce compressive residual stresses on component surfaces for increasing the fatigue ...
Investigation of residual stress, stress relaxation and work hardening effects induced by shot peening on the fatigue life of AA 6005-T6 aluminum alloy
(2019-01-01)
Fatigue strength improvement of mechanical components is one of the most challenging problems in engineering. One of the known ways to improve fatigue life is by using the shot peening process. However, it is complex to ...
Evaluation of WC-10Ni thermal spray coating with shot peening on the fatigue strength of AISI 4340 steel
(Elsevier B.V., 2010-01-01)
Fatigue failure is a result of a crack initiation and propagation, in consequence of a cyclical load. In aeronautical components as landing gear the fatigue strength is an important parameter to be considered in project, ...
Evaluation of shot peening on the fatigue strength of anodized Ti-6Al-4V alloy
(ABM, ABC, ABPol, 2006-03-01)
The increasingly design requirements for modern engineering applications resulted in the development of new materials with improved mechanical properties. Low density, combined with excellent weight/strength ratio as well ...
The surface treatment influence on the fatigue crack propagation of Al 7050-T7451 alloy
(Elsevier B.V. Sa, 2009-04-15)
The objective of this research is to evaluate 100 mu m, thickness hard chromium electroplated coating on the fatigue crack propagation of Al 7050-T7451 alloy. The shot peening process was carried out to create residual ...
Effect of the shot peening process on the fatigue strength of SAE 5160 steel
(2019-06-01)
The fatigue behaviour of SAE 5160 steel was evaluated before and after applying a shot peening process by using different Almen intensities and surface coverings (uncovered, partial coverage and total coverage). In the ...
Improvement in the fatigue strength of chromium electroplated AISI 4340 steel by shot peening
(Wiley-Blackwell Publishing, Inc, 2009-02-01)
In landing gear, an important mechanical component for high responsible applications, wear and corrosion control is currently accomplished by chrome plating or hard anodising. However, some problems are associated with ...
