SiC particulates reinforced Al matrix composites were fabricated by thermal spray process, and the dry sliding wear behavior against four different counterparts was investigated under a varying of the sliding speed and the applied load conditions. Al/SiC composites were fabricated by flame spraying, and the dry sliding wear tests were performed using the sliding speed of 0.4 m/s and 0.8 m/s at the applied load of 3 N. Sliding distance was kept at 1000 m for all the tests. Al2O3, ZrO2, Si3N4 and AISI 52100 balls were used as the counterparts. Wear tracks on the Al/SiC composites were investigated using scanning electron microscope (SEM) and energy dispersive X-ray spectroscopy (EDX). It was revealed that wear behavior of Al/SiC composites was much influenced by counterpart materials.

Al Matrix Composites

SiC particulates reinforced with Al matrix composites were fabricated using a thermal spray process. In addition, the dry sliding wear behavior was investigated using various sliding speeds and applied loads. Premixed Al and SiC powder was sprayed onto an Al6061 substrate by flame spraying, and dry sliding wear tests were performed under varying sliding speed and applied load conditions. Wear behavior of the composites were studied using a scanning electron microscope(SEM), X-ray diffraction(XRD) and a surface roughness tester.

Thermally Sprayed

This study aims at investigating the effect of the sliding speed and the applied load on the dry sliding wear behavior of thermally sprayed Ni-based self-flux alloy coating. Ni-based self-flux alloy powders were flame-sprayed onto a carbon steel substrate and then these coatings were heat-treated at temperature of 1000 oC. Dry sliding wear tests were performed using the sliding speeds of 0.2, 0.4, 0.6 and 0.8 m/s and the applied loads of 5, 10, 15 and 20 N. AISI 52100 ball (diameter 8 mm) was used as counterpart material. Wear behavior of Ni-based self-flux alloy coatings was studied using a scanning electron microscope (SEM) and energy dispersive X-ray spectroscopy (EDX). It was revealed that microstructure and wear behavior of the Ni-based self-flux alloy coatings were much influenced by the sliding speed and the applied load.

Wear Tests

The correlation between applied load and sliding speed on the wear behavior of tamarind wood was analyzed using statistical analysis. Dry sliding wear tests were conducted using the block-on-roller technique while mass loss was measured by using a micro balancer. The test specimens measured 20 mm by 20 mm by 10 mm and were made of tamarind wood. The roller which acted as the counter surface material was made of mild steel (120 HV), cut from a commercial mild steel bar (50 mm in diameter) measuring 300 mm in length. Dry sliding wear tests on tamarind wood was conducted using different sliding velocities (60 rpm, 95 rpm and 145 rpm) and applied using different loads (10 N, 20 N and 30 N). The test results were analyzed and inferred using linear correlation and regression. The results suggest that sliding speed and applied load have a significant and positive influence on mass loss. A direct correlation between applied load and sliding speed on the mass loss of tamarind wood was evident. Regression analysis indicated that the contribution of applied load and sliding speed on the mass loss of tamarind wood under dry sliding was at 82.6%.

Rubber Content

The effect of crump rubber on the dry sliding wear behavior of epoxy composites is investigated in the present study. Wear tests are carried out for three levels of crump rubber (10, 20, and 30 vol.%), normal applied load (30, 40, and 50 N), and sliding distance (1, 3, and 5 km). The wear behavior of crump rubber–epoxy composites is investigated against EN31 steel discs. The hybrid mathematical approach of Taguchi-coupled Grey Relational Analysis (GRA)—Principal Component Analysis (PCA) is used to examine the influence of crump rubber on the tribological response of composites. Mathematical and experimental results reveal that increasing crump rubber content reduces the wear rate of composites. Composites also show a significant decrease in specific wear values at higher applied loads. Furthermore, the coefficient of friction also shows a decreasing trend with an increase in crump rubber content, indicating the effectiveness of reinforcing crump rubber in a widely used epoxy matrix. Analysis of Variance (ANOVA) results also reveal that the crump rubber content in the composite is a significant parameter to influence the wear characteristic. The post-test temperature of discs increases with an increase in the applied load, while decreasing with an increase in filler loading. Worn surfaces are analyzed using scanning electron microscopy to understand structure–property correlations. Finally, existing studies available in the literature are compared with the wear data of the present study in the form of a property map.

Pin On Disk

In the present work, an experimental investigation has been made of a dry sliding wear rate for aluminum, aluminum alloy (Al-Fe-V-Si), bronze, stainless steel 304 and structural steel ASTM A36, using a pin-on-disk apparatus under the effect of sliding speed and time at constant load. The materials were tested on two types of abrasive surfaces with a grit surface of 24 and 36. The applied load was equal to 2500 grams and the same load was used for all of the pins that were tested. The relative wear was indicated by the loss in length and loss in mass. The results show that the wear rate will directly proportional with sliding speed and time, and the stainless steel has less wear rate than the other materials.
