Microindentation of Polymethyl Methacrylate (PMMA) Based Bone Cement
Journal Title: Tribology in Industry - Year 2011, Vol 33, Issue 4
Abstract
Characterization of polymethyl methacrylate (PMMA) based bone cement subjected to cyclical loading using microindentation technique is presented in this paper. Indentation technique represents flexible mechanical testing due to its simplicity, minimal specimen preparation and short time needed for tests. The mechanical response of bone cement samples was studied. Realised microindentation enabled determination of the indentation testing hardness HIT and indentation modulus EIT of the observed bone cement. Analysis of optical photographs of the imprints showed that this technique can be effectively used for characterization of bone cements.

Dependence of Wear Intensity on Parameters of Tribo Units
The degree of dispersion of particles of pollution and their amount in the lubricating medium substantially affects the anti-wear properties of the latter. At the same time, if the particle size of the contaminants is 5...
Thermal and Dry Sliding Wear Behavior of Plasma Sprayed Red Mud-Fly Ash Coatings on Mild Steel
The present work focuses to understand the limitations towards high temperature applications of plasma sprayed coatings like pure red mud, composited with varying weight % (10, 20 and 50) of fly ash on mild steel. Sprayi...
The Factor of Structure and Mechanical Properties in the Production of Critical Fixing Hardware 38XA
Fixing hardware made of carbon, high-carbon, and alloyed wires is one of the widespread critical parts in mechanical engineering. The characteristics of fixtures and fasteners and their performance figures are assessed a...
Wear Behavior of PVD-Coatings
In cold forging high tribological loads often lead to premature tool failure. If the cause of failure is wear, an extension of tool life can be achieved by applying PVD coatings. According to the different load cases ap...
Effect of Surface Roughness and Temperature on EHL for Parallel Surfaces Subjected to High Acceleration
Frictional wear is one of the most common causes of material failure. One of the most common techniques to overcome this is to lubricate the surfaces in contact using an optimum amount of appropriate lubricant. Same tech...
