An investigation of electrolytic surface damages and electroplated crhomium effects on fatigue behavior of high strength steel
(2001-12-01)
Fatigue crack initiation occurs at the surface, although sub surface nucleation has also been reported. Localized imperfections like inclusions close to surface and surface small pits can result in crack sources. Coatings ...
EVALUATION OF HVOF SPRAYED WC-13Co-4Cr AND HARD CHROMIUM ELECTROPLATED ON STAINLESS STEEL 15-5PH FATIGUE STRENGTH
(Inegi-feup, 2017-01-01)
Fatigue failure is the result of a crack initiation and propagation as a consequence of cyclic loading. In the aeronautical industry, for components like landing gear, fatigue strength is an important parameter to be ...
Plasma immersion ion implantation on 15-5PH stainless steel: Influence on fatigue strength and wear resistance
(2017-05-31)
Surface improvement in steels is of great interest for applications in industry. The aim of this investigation is to study the effect of nitrogen ion implantation on the axial fatigue strength and wear resistance of 15-5 ...
A study of the influence of WC-10Co-4Cr HVOF coating on mechanical properties of AISI 4340 steel
(2001-01-01)
Aircraft landing gear manufacturers are considering WC thermal spray coatings applied by the high-velocity oxygen-fuel (HVOF) process as an alternative to hard chrome plating. The question to be answered is if the performance ...
Influence of shot peening on the fatigue strength of Custom 465 stainless steel for aeronautic application
(Trans Tech Publications Ltd, 2014-01-01)
This project was originated from the national aircraft industry requirements to reduce the use of coated materials with electroplated chromium or cadmium that produce waste, which is harmful to health or the environment. ...
FATIGUE IN CUSTOM 465 STAINLESS STEEL FOR AERONAUTIC APPLICATION
(Inegi-inst Engenharia Mecanica E Gestao Industrial, 2012-01-01)
This project was originated from the national aircraft industry requirements to reduce the use of coated materials with electroplated chromium or cadmium that produce waste, which is harmful to health or the environment. ...
Fatigue Performance of AISI 4340 Steel Ni-Cr-B-Si-Fe HVOF Thermal Spray Coated
(2015-01-01)
Coatings are deposited on high strength materials to improve the surface degradation resistance of several elements. As a consequence, the fatigue strength of coated materials is significantly influenced by internal residual ...
