Abrasive wear resistance of white cast iron can be improved by adding transition metals due to carbide formation and matrix stabilization. However, it must also affected carbon content which has received little attention from researchers. Therefore, this study would investigate the influence (1.4 2.8 wt.%) C on three body abrasive characteristics 28Cr-3Ni alloys. High Cr-based multi-component i...

High densities in bunker silos minimize losses and reduce storage costs; however, the guidelines to attain high densities are based on relatively little research. The objective of this study was to determine those practices or factors most correlated with bunker silo density. Density was measured in 175 bunker silos across Wisconsin using core samples collected at chest height (1.13 m, 3.70 ft,...

Abrasion-resistant materials have attracted great attention for their broad applications in industry, biomedicine and military. However, the development of abrasion-resistant materials that have with unique features such as being lightweight and flexible remains a great challenge in order to satisfy unmet demands. The outstanding performance of natural abrasion-resistant materials motivates the...

BACKGROUND Excessive shoe heel abrasion is of concern to patients and shoe manufacturers, but little scientific information is available about this feature and its possible causes. The purpose of this study was to relate this phenomenon with biomechanical factors that could predispose to shoe heel abrasion. METHODS Ninety-seven recruits (median age 25) were enrolled in this study. Shoe abrasi...

this research explores the possible benefits to be derived from interactions between wheels, for supporting a greater proportion of applied loads in the shallower soil layers. this creates possibilities for reducing the risk of deep soil compaction. previous research indicated that different interaction modes occurred under simulated wheel arrangements, being mostly dependent upon the spacing b...
