On the specific wear rate of polymer composites

Advances in Polymer Technology, 1989
AbstractA numerical calculation of specific wear rate has been attempted for two kinds of sliding wear (abrasive and adhesive) using a phenomenological equation derived from the concepts of crack propagation, delamination physics, and bond rupture.

Differentiation of specific wear rates of AISI 304 austenitic and AISI 2205 duplex stainless steels at room and high temperatures

Heliyon, 2022
Austenitic and duplex stainless steels are used in numerous applications at room and high temperatures. However, their wear behaviour at high temperatures has not yet been sufficiently investigated. Therefore, in this work, wear tests were carried out on specimens of AISI 304 austenitic steels and AISI 2205 duplex stainless steels at temperatures (30 ...

Development of Mathematical Model to Predict Specific Wear Rates of Graphite Seal

Journal of the Korean Society of Propulsion Engineers, 2014
ABSTRACT The dry sliding wear behavior of graphite that is used as the sealing material to cut off hot gas was evaluated as a function of applied load, sliding speed and temperature. The reciprocating wear tests were carried out at room temperature and elevated tempera tures.

Effect of Reinforcements on Specific Wear Rate of Al 7075 / Tib2/ Cr2O3 Hybrid Composites

International Journal of Innovative Technology and Exploring Engineering, 2019
A composite material contains different reinforcing elements added to the major material that forms the base matrix. In this work Aluminium 7075 matrix was reinforced with 12% TiB2and 4%, 6% and 8% Cr2O3 and the wear behavior of this composite was studied. The composite material was prepared by the process of stir casting. The rate of specific wear was
