Basic Mechanisms and Predictive Testing of Tire-Road Abrasion

During Hertzian contact and sliding rubber friction over a road's periodical roughness, the framework of the paper is a very simple physical model. This results also shows that tire wear under moderate severity conditions cannot be explained by abrasive wear tests in the laboratory, e. g.

Tire-Abrasion Particles in the Environment

Driving a car on a highway is inevitably linked to the production of tire-abrasion particles. These tire-abrasion particles are then transported by wind and water to various environmental compartments, whereby road runoff plays a major role in the distribution. These particles are once in the atmosphere and water, which causes degradation and concomitant release of essential tire components, such as zinc and various organic tire additives.

Wear Behavior of Hot Rolled 400 HB Grade Martensite-Ferrite Duplex Steel under Abrasion-Adhesion Condition

Martensite-ferrite duplex steel, a new form of wear-resistant material used in the manufacture of heavy-haul carriages, is hot rolled 400 HB grade martensite-ferrite duplex steel. With the increase of air-cooling time, the amount fraction of ferrite and retained austenite rises during the step cooling process of TMCP. The experimental steel with the highest hardness has the worst wear resistance in this analysis. HR-3's wear mechanism is delamination, and HR-9 and HRT-9's wear mechanisms are plowing grooves and adhesion, as shown by a slurry groove.

Microbial community shifts induced by plastic and zinc as substitutes of tire abrasion

Plastic and zinc are two key components of tires, and may be used as substitutes for tire abrasion to investigate the effect on microbial life. Plastic and zinc concentrations on a freshwater microeukaryotic population in a 14-day exposure period are investigated by the 18S V9 region's high-throughput sequencing of the 18S V9 region. A change in community organization as a result of zinc and nanoplastics is evident, but not due to nanoplastics, despite generally unchanged diversity on exposure to zinc and nanoplastics. Nanoplastic particles hardly impact the community, arguably, but zinc exposure leads to dramatic functional abundance shifts in the trophic environment, indicating the trophic mode. Though phototrophic organisms are decreasing in the presence of zinc, the phenolic fraction initially benefited, and the heterotrophic fraction was also benefiting throughout the exposure period. Despite lasting shifts in taxon composition, the functional community of a nonprofit community is still highly divided following the introduction of zinc but returns to the original state.

Corrosion and impact–abrasion–corrosion behaviors of quenching–tempering martensitic Fe–Cr alloy steels

In the corrosive slurry of a copper mine compared to high manganese steel, the corrosion and impact of quenching u2013corrosion reactions of quenching Fe2013Cr martensitic steels for ball mill liner were investigated. Compared to the high manganese steel, particularly the alloy steel with a carbon content of 0. 3 percent, the quenching Feùu2013empering Feu2013Cr martensitic steel had better results in the corrosive slurry with reduced corrosion resistance in the corrosive slurry with 0. 3 percent. During the production of new materials for ball mill liner, the steel's impact and cracking resistance should also be given special attention.
