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 ...

It is well known that fatigue behaviour is an important parameter to be considered in mechanical components subjected to constant and variable amplitude loadings. In combination with corrosion phenomenon, fatigue effects ...

The aim of the present work is to identify an environmentally clean coating process that will present lower influence in the Ti-6Al-4V fatigue strength. Axial fatigue tests of Ti-6Al-4V alloy TiN, CrN and WC:H (tungsten ...

In this paper the fatigue damage accumulation under block program loading is investigated. Alternative flexion bending fatigue tests with a single change in stress amplitude are performed at room temperature for step-down ...

Bending fatigue tests were carried out to clarify the effects of heat treatment parameters: temperature and time after cadmium electroplating on a high strength steel, to avoid hydrogen embrittlement. Temperatures heat of ...

This study compares the fatigue behavior of quenched/tempered and austempered super clean Cr–Si high strength steels (HSS). The microstructure of the quenched and tempered steel consisted of tempered martensite and that ...
