Analysis of the PM Bearing – Spindle Contact Using Finite Element Method
(UDJG, 2011)Using PM (Powder Metallurgy) technologies, new antifriction materials based on iron-copper powders with different addition elements were developed. The elemental powder mixtures were compacted at different pressures and ... -
Modelling of some Degradation Processes by Corrosion Fatigue of Metallic Surfaces
(UDJG, 2011)Based on the well known fatigue corrosion effects, the mechanical stress and the corrosive environment have a significant effect on the prediction of the lifespan of the equipments that work in corrosive environment, two ... -
Experimental Determination of Contact Area Between a Sphere and a Circular Plate Using a Technique Based on Laser Profilometry
(UDJG, 2011)This paper presents the experimental determination of contact area between a steel sphere and a sapphire circular plate, using a technique based on laser profilometry. The reflectivity value is smaller inside contact area ...
