at Batu Gajah-Ipoh, Malaysia. In-situ testing results show that the subsurface soil comprises mainly of sand and silty sand through the investigated depth extended to 10 m. Groundwater is approximately... with depth.Key words:cone penetration test; granular soil; compaction; rapid impact compaction; relative density; settlement; improvement depth; in-situ testing......
Thickness effects on corrosion and wear resistance properties of micro-arc discharge oxide coatings on AZ91D magnesium alloys HUANG Wei-jiu(黄伟九), LIU Ming(刘 明), LI Zhao-feng(李兆峰), ZENG Rong... of the MAO coatings is four to six times higher than that of the magnesium alloy substrate. The MAO coatings have much better wear-resistance and corrosion resistance abilities than those of magnesium......

of 4.9 N. Sliding wear tests were carried out on a vertical pin-on-disc wear testing machine with loads of 29.4 and 49 N and speeds of 400 and 640 r/min corresponding to 2.512 and 4.019 m/s, respectively.... The properties were characterized in terms of microstructure, hardness and sliding wear behaviour and then compared between the extruded and cast alloys and composites, in order to understand......
) Abstract: The effects of silicon particle(Sip) content and testing temperature on wear properties of in-situ Sip/ZA27 composites were investigated. The results indicate that the wear resistance increases firstly, then decreases, while finally increases again. The wear resistance decreases with the increase of testing temperature. But the decrease ranges of wear resistance of the composites......

at high temperatures under dry sliding conditions using a pin-on-disc wear testing machine. The results indicate that the wear rate increases with the increase of applied load and sliding distance... wear mechanism is abrasion at low applied loads. The mild delamination wear accompanying with adhesion wear is the predominant wear mechanism under high applied loads at 150 ℃, whereas the severe......
