contact fatigue - asm international

A Standing Contact Fatigue (SCF) test set up has been developed in order to facilitate quick testing of contact fatigue resistance of material surfaces In this method the sample is pressed against a hard ball rapidly and the resulting crack formation is studied in order to evaluate the SCF resistance Induction hardened surfaces of cam-ring steel and steels with pearlitic martensitic 2004-2-5SF2M-ASM International - The Materials Information Society (US) members an important point of contact with the North American materials community while providing useful benefits from a respected Le CETIM a l'intention d'organiser un congrs international sur la fatigue

Experimental Research of Gear Contact Fatigue

This paper deals with experimental research of gear contact fatigue strength This research is realized on the universal experimental machine with gear samples from non-alloy stainless steel for through hardened C45 In particular it deals with testing methodology and evaluation method of allowable number in contact (fatigue limit)

ASM Handbook Volume 19: Fatigue and Fracture is the first comprehensive reference book to put critical information on both fatigue and fracture mechanics in one convenient volume It provides comprehensive data on a broad spectrum of engineering structural materials and alloys

The mechanism of contact fatigue can be understood in terms of several sources of stress concentration or stress raisers within the macroscopic Hertzian stress field This article focuses primarily on rolling contact fatigue of hardened bearing steels

A fracture mechanics model has been developed to estimate the fretting fatigue strength and the service life of structural components Integrated in this model is a contact problem solver that is automated to deal with the geometric and material nonlinearities of the problem

Contact Fatigue Crack Growth in PVD

The aim of this work is to investigate the (rolling) contact fatigue behaviour of transmission spur gears coated with PVD (Physical Vapour deposition) thin hard films Numerical models of coated steel and titanium spur gears were developed The effect of the residual stress gradient induced by the coating deposition process was considered in the calculations

Rolling-contact fatigue (RCF) is a surface damage process due to the repeated application of stresses when the surfaces of two bodies roll on each other This article briefly describes the various surface cracks caused by manufacturing processing faults or blunt impact loads on ceramic balls surfaces

2019-11-15In this work an experimental-numerical evaluation of the standing contact fatigue testing of a nitrided AISI 316L steel was developed The nitride layers were formed at the surface of an AISI 316L steel by a salt bath nitriding process at a temperature of 580 C for 1 3 and 5 h of exposure time obtaining three different layer thicknesses
