ball mills are common grinding equipment in mineral processing industries. ball wear results from three mechanisms namely impact, abrasion and corrosion. of these, the corrosion mechanism is the least investigated, due to its chemical-electrochemical nature. therefore, the aims of this research were to investigate the grinding chemistry influence (slurry ph, solid percentage, water chemistry an...

the aim of the present study was to investigate the effect of quenching and tempering temperatures on themicrostructure, mechanical properties and the wear characteristics of medium carbon-high chromium wear resistantsteel. in addition, the dominant wear mechanisms were studied. for this purpose, austenitizing and temperingtemperatures were selected in the ranges of 900- 1000 °c and 300- 500 °c...

the aim of this research was to study the wear behavior of 42crmo4 steel/zro2 composite with 10 and 30 ppi performed ceramic and compare it with the un-reinforced steel under different applied loads. the composite specimens were obtained by pressureless infiltration of the melt into a preformed ceramic of zirconium oxide. the effect of applied load on the specimens wear behavior was studied by ...

The wear mechanism of plasma electrolytic nitrocarburised (PEN/C) 316L stainless steel samples was studied after a pin on disc wear test. The surface morphology of samples after application of PEN/C process was studied using scanning electron microscope technique. The sliding tracks resulting from the wear tests on the treated specimens indicated no signs of plastic deformation and adhesive wea...

in this research, our attempt is to monitor tool wear through the chip formations, forces, and temperature of edge of drill while drilling in superalloy plate to optimizes effective parameters, which lead to facilitate machining process to, improved tool life, and enhance the productivity. in this study, inconel718 superalloy material, and cemented coated carbide tool was selected for investiga...

in the present work, the aa2124/25vol.%mosi2 composite was produced by powder metallurgy technique. the aluminum alloy 2124 powder was produced by gas atomization method and the mosi2 intermetallic particles were produced through combustion synthesis. the aa2124 matrix powder was mechanically blended with 25vol.%mosi2 using a ball milling mixer. the blended powder mixture was encapsulated and t...

The effects of applied load, sliding speed and sliding distance on the dry sliding wear behavior of aged Al-SiCp-Gr composites were investigated. The specimen were fabricated by stir-casting technique. The pin-on-disc wear testing machine was used to investigate the wear rate by design of experiments based on L27 using Taguchi technique. Sliding distance was the most important variable that inf...
