The wear failure of traction wheels in orchard transport severely restricts the stability conveyors and impedes mechanization work. In this study, thermal-diffusion chromizing method was employed to increase hardness a wheel for enhancement resistance. results show that uniform dense chrome coating with thickness 16 μm formed on surface. revealed have 1752.7 HV benefited from formation Cr-C com...

This paper investigates the effect of ground and fumed silica fillers on suppressing DC erosion in silicone rubber. Fumed are incorporated rubber at different loading levels comparatively analyzed this study. Outcomes +DC inclined plane tracking test indicate a better performance for filled composite despite having lower thermal conductivity compared to composite. Results simultaneous thermogra...

Single and multipass two-body and three-body abrasive wear behaviour of various polyaryletherketone composites have been carried out by using a pin-on-disc machine and a rubber wheel abrasion test (RWAT) rig. Abrasive wear studies were conducted under different loads and sliding distances. Comparative wear performance of all the composites at different loads shows that specific wear rate (Ko) o...

Ethylene is a stimulant to increase natural rubber latex. After ethylene application, both fresh yield and dry matter of latex are substantially improved. Moreover, we found that ethylene improves the generation of small rubber particles. However, most genes involved in rubber biosynthesis are inhibited by exogenous ethylene. Therefore, we conducted a proteomics analysis of ethylene-stimulated ...

in this study, in order to investigate the effect of increasing the manganese content on microstructure and mechanical properties of high manganese austenitic steels, three alloys with successive increases in weight percentages of manganese (7.55, 13.1, and 16.5) and carbon (0.8 and 1.2) were cast in the presence of a constant amount of chromium (1.5 wt.%) and silica (0.6 wt.%). the samples exp...

Abstract The mining industry needs a low-cost and reliable breakage characterization test which can rapidly process large number of samples for geometallurgical modelling. more are tested, the better is understanding ore hardness variability lower design or production risks. proposed solution new testing device, herein named Geopyora, variation roll crusher with an adjustable gap instrumentatio...

Abstract In this investigation, atmospheric plasma spray (APS) and high-velocity oxy-fuel (HVOF) techniques were used to produce AlCoCrFeNi coatings. High-entropy alloys (HEAs), due their mechanical, chemical, physical properties are capturing the attention of international scientific community. Starting feedstock powders characterized in terms size, phase, corrosion test NaCl, ball on disk, ru...

Rubber tree production is reduced by weeds that compete for environmental resources; therefore, the timing and duration of weed control influences weed interference. The objectives of this study were to evaluate the growth of rubber tree (Hevea brasiliensis) plants, to determine the critical period for weed control, and to evaluate the growth recovery of rubber trees that coexisted with weeds f...

Heavy aircraft main landing gear tyres skid immediately after touchdown as result of the high slip ratio between the tyres and runway, which lead to tyre wear and smoke. In this paper, the tyre wear is modelled on the Archard theory using ANSYS mechanical transient, to reveal the wheel’s dynamic and the tyre tread wear. The wheel’s dynamic and the amount of wear are calculated for initially sta...
