.... MACM was used to synthesize polymer nanocomposites with varied CNT volume fractions (5% and 10%). Mechanical properties, including hardness, tensile strength, elastic modulus and flexural strength, were assessed through shore D hardness, tensile test and flexural test. Pin-on-disc wear tests were...

... by Archimedian principle and theoretical density by rule of mixture and hardness test to investigate mechanical property. The dry sliding wear behaviour of the composites was investigated using pin-on-disc tribometer with various applied loads of 15 and 20 N, with constant sliding velocity and distance. The wear...

... conducted on each diamond coating using Berkovich nanoindenter for the measurement of their hardness and elastic modulus values. Also, the wear characteristics of all sliding bodies were studied under varying load conditions using cumulative weight loss and density method. Findings Depositing any type...

.... An impact-wear tester is used to validate the model results. Findings The measurements indicate an increase in surface hardness because of the several impacts. It is considered in the wear predictive model. Originality/value The model predictions compared with the experimental data, obtained from...

... of the joint. The rotation is stopped, and the maximum compacting pressure is introduced, which causes the intensive plastic deformation (Figure 1(a) – Position 4) and a wreath is formed (the “mushroom”). That is how the solid joint is formed. During the process of intensive friction, the hard-facing...

... sustainability by evaluating the relationship between the quality of material alloys and heat treatment as well as cultural aspects such as the treatment on the HSS hacksaw blade that will affect the material hardness. Design/methodology/approach The quality of HSS hacksaw blade samples was analyzed by using...

...BM Viswanatha; M Prasanna Kumar; S Basavarajappa; TS Kiran Purpose – This paper aims to investigate the microstructure, hardness and tribological properties of hypoeutectic (Al-7Si) matrix reinforced with fixed quantities of 3 Wt.% graphite (Gr) and x Wt.% SiCp (x = 3, 6 and 9) hybrid composites...

... the least yield strength, (UTS) and ductility. However, palm oil and olive oil have better load reduction than other lubricants. Furthermore, from the hardness results, though scattered, all of the points at the tensile strained side of the extrudate lie within a reasonably narrow band, suggesting a high...

... structure was clearer. Whenever applying higher temperature and longer boronizing time, wear decreased and hardness values increased. It was also determined that when boronizing was conducted at 900 and 1,000°C for at least four to six hours, better results were obtained. Furthermore, the increment...

...Ilyas Uygur Purpose To provide information about technical data; wear behaviour of worn rotor parts in mining industry and for the other application of ferrous alloys. Design/methodology/approach Wear behaviour of the various filler wires were tested (tensile, hardness, and wear) and compared...
