چکیده
This article presents the results of an experimental study which aimed to evaluate the effect of surface wear on the friction properties of geosynthetic interfaces constituted of geomembranes and geospacers. The tests were performed in ramp test device, and the results showed the different sensitivities of the interfaces to the wear process. For the particular types of interfaces considered in the experiment, the surface wear can increase, decrease or maintain the original friction properties of the geosynthetic interface, with direct effects on the stability under service condition.

متن کاملEffect of SiC nanoparticles addition on mechanical properties and wear resistance of cemented carbides fabricated by spark plasma sintering
WC-10Co cemented carbides containing 1 to 4 wt% SiC nanoparticles were prepared by spark plasma sintering. The effects of SiC content on microstructure, mechanical properties and wear resistance of the sintered materials were studied. Microstructural studies showed that SiC addition resulted in WC grain coarsening. In addition, the hardness decreased with increasing SiC content. However, the fr...

متن کاملThe effect of TiO2 concentration on microstructure, corrosion behavior and wear behavior of Ni-P-W-TiO2 coating
Nickel-phosphorus coatings (Ni-P) are widely used in industry due to their high hardness, corrosion resistance and very good mechanical and chemical properties. Oxide particles such as TiO2 can be used to increase the wear resistance of these coatings. In this study, the Ni-P-W-TiO2 composite coating was deposited on the AISI 304L steel substrate using the electroplating method. Electroplating ...
