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 ...
Effects of tungsten carbide thermal spray coating by HP/HVOF and hard chromium electroplating on AISI 4340 high strength steel
In cases of decorative and functional applications, chromium results in protection against wear and corrosion combined with chemical resistance and good lubricity. However, pressure to identify alternatives or to improve ...
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 ...
The significance and determination by image analysis of microcrack density in hard chromium plating
It is well known that the microcrack density is a fundamental parameter in hard chromium electroplating. The chemical and mechanical properties of this coating are widely dependent on its microcrack density. In this paper ...
The effect of WC-17Co thermal spray coating by HVOF and hard chromium electroplating on the fatigue life and abrasive wear resistance of AISI 4340 high strength steel
(Freund Publishing House Ltd, 2003-01-01)
One of the most interesting alternatives for replacement of hard chrome plating is tungsten carbide thermal spray coating applied by the high velocity oxy-fuel (HVOF) process which presents a safer, cleaner and less expensive ...
Effect of electroless nickel interlayer on the fatigue strength of chromium electroplated AISI 4340 steel
(Elsevier B.V., 2007-04-01)
Deposition of wear-resistant hard chromium plating leads to a decrease in the fatigue strength of the base material. Despite the effective protection against wear and corrosion, fatigue life and environmental requirements ...
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 ...
STUDY OF THE EFFECT OF TEMPERATURE ON THE HARDNESS, GRAIN SIZE, AND YIELD IN ELECTRODEPOSITION OF CHROMIUM ON 1045 STEEL
(Sociedad Chilena de Química, 2008)
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, ...
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 ...
