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 ...
