behaviour of the alloys was also substantiated further through the characteristics of their affected surface and subsurface regions. Key words: zinc-based alloys; slurry wear behaviour; material... during the tests. The role of a reaction/corrosion product in controlling the wear behaviour of materials in slurry depends on its compactness (inverse of permeability) and adhesiveness......
°. However, increasing rotation speed of the samples results in exponential increase in wear rate. The findings are substantiated with the metallographic study of worn surface. Key words: aluminum; slurry... on the erosive wear behavior of ductile material rotating in slurry tank. Erosion wear behavior of commercial grade aluminum has been studied by rotating the specimens in a slurry tank containing 40......
Microstructure and Sliding Wear Behaviour of Ni(Cr)-TiB2 Coatings Deposited by HVOF Spraying of SHS Powders Zohreh Sadeghian1,Behnam Lotfi2 (1.Department of MaterialsScience and Engineering... the microstructure and sliding wear behaviour of cermet coatings deposited by high velocity oxy-fuel (HVOF) spraying. Two cermets were prepared with the following target compositions namely, Ni (Cr)-65 wt.% TiB2......
Wear Behaviour of CTC/FeCrCSi Composite王华明,纪嘉林摘 要:<正> To bring the excellent abrasion-resistant po-tential of carbide into full play,composites... little effect on wear rate for composites basedon martensite white cast iron,but wear rate ofconventional wear-resistant materials increaseslinearly in a very steep slope as the nominal stressincreases......
. The sliding wear behavior of magnesium alloys is an important consideration. There are some works dealing on the wear behaviour of magnesium alloys such as Mg-Al-Zn [5,6], Mg-Zn-Y [3,7] and Mg-Zn-Ce [8,9... a better tribological property than AZ91 alloy under high load [3]. Mg-25Zn-2Y quasicrystal alloy exhibits low friction coefficient and good wear resistance [7]. Dry sliding wear behaviour of ZE41A alloy has......
), and the structure of hardfacing layer was analyzed by X-ray diffracto-metry(XRD) at room temperature. 2.4 Wear test Slurry erosive wear tests were carried out on a MSL-23 type water slag wear tester... for improving the bonding strength of the hardmetal and Cu-based alloy. Fig.4 SEM morphology and elemental distributions of interface of YT758/CuZnNi The variation of slurry wear......
