INVESTIGATION OF CHANGES OF FERROMAGNETIC FLUIDS VISCOSITY ACTIVATED BY STEADY MAGNETIC FIELDS
This paper presents the results of viscosity measurements for selected ferromagnetic fluids subjected to a DC magnetic field at various values of magnetic flux density. The research takes into consideration the dependenc...
TRIBOLOGICAL PROPERTIES OF TI/A-C:H NANOCOMPOSITE CARBON BASED COATINGS
The paper presents the results of mechanical and tribological tests of Ti/a-C:H nanocomposite carbon coatings and a-C:H hydrogenated carbon coating. All coatings were deposited by magnetron sputtering technique at variou...
ANALYSIS OF FRICTION JOINING OF PRESSED GRATING FLATS
The aim of the paper is to analyse the friction forces in joints of pressed platform flat and transverse bars. Actual friction forces could have been determined based on the diagrams of force changes in the process of re...
BUILDING A FORMULA FOR A COMPOSITE FRICTION MATERIAL FOR BRAKES
Composite friction materials used today contain over 20 components. Asbestos and lead has been eliminated from their contents. New formulas contain no mercury, cadmium, antimony, and chrome VI. Friction materials are des...
THEORETICAL AND EXPERIMENTAL ANALYSES OF THE INFLUENCE OF NORMAL VIBRATIONS ON FRICTION FORCE IN SLIDING MOTION
The computational model as well as the test stand and results of some simulation and experimental tests on the influence of normal vibration on friction and driving forces in sliding motion are presented in this paper. I...
