Influence of anodization on the fatigue strength of 7050-T7451 aluminium alloy
(Blackwell Publishing, 2007-11-01)
In recent years, with higher demand for improved quality and corrosion resistance, recovered substrates have been extensively used. Consequently residual stresses originated from these coatings reduce the fatigue strength ...
Plasma immersion ion implantation and shot peening influence on the fatigue strength of AA 7050-T7451 aluminum alloy
(2020-03-01)
The 7xxx aluminum alloy series is applied in aircraft components that demand high specific mechanical strength and fatigue resistance. The corrosive environment and friction forces imposed on those components reduce the ...
Effect of WC-10%Co-4%Cr coating on the Ti-6Al-4V alloy fatigue strength
(Elsevier B.V. Sa, 2009-05-15)
High strength/weight ratio and effective corrosion resistance are primary reasons to use titanium alloys replacing steel and aluminum in some aeronautical components. However, titanium alloys have poor tribological properties, ...
Evaluation of WC-10Ni thermal spraying coating by HVOF on the fatigue and corrosion AISI 4340 steel
(Elsevier B.V., 2010-01-01)
Shot peening is a surface process widely used to improve the fatigue strength of materials, through compressive residual stresses induced in their surface layers. Considering mechanical components for high responsible ...
Residual stress influence on fatigue lifetimes of electroplated AISI 4340 high strength steel
(Blackwell Publishing, 2007-11-01)
Residual stresses play an important role in the fatigue lives of structural engineering components. In the case of near surface tensile residual stresses, the initiation and propagation phases of fatigue process are ...
Fatigue in AISI 4340 steel thermal spray coating by HVOF for aeronautic application
(Elsevier B.V., 2010-01-01)
Currently, high-strength materials, particularly AISI 4340 steel, are used in several landing gear components. Due to the high resistance to wear and corrosion required, the components are usually coating by hard chromium. ...
Surface Microstructure Modification in Square Extruded Al-Nb Powder Composites by Shot Peening
(IOP Publishing, 2014-10)
75%Al-25%Nb powder composites, fabricated by square shape cold extrusion, were subject to shot peening treatment with full coverage. Shot peening results in a high number of intense local deformations, with a surface ...
Effects of surface treatments on the fatigue strength of AISI 4340 aeronautical steel
(Elsevier B.V., 2001-08-01)
Internal residual stresses significantly influence the fatigue strength of coated materials. It is well known that chromium plating is the most used electrodeposited coating for important industrial applications. However, ...
Coating residual stress effects on fatigue performance of 7050-T7451 aluminum alloy
(Elsevier B.V., 2007-10-15)
The tendency of the aircraft industry is to enhance customer value by improving performance and reducing environmental impact. In view of availability, aluminum alloys have a historically tendency to faster insertion due ...
Carbon fiber non-crimp multi-axial reinforcement and epoxy mono-component system composite: fatigue behavior
(Elsevier B.V., 2010-01-01)
Fiber reinforced polymer composites have been widely applied in the aeronautical field. However, composite processing, which uses unlocked molds, should be avoided in view of the tight requirements and also due to possible ...
